Trap–neuter–return (TNR) is a type of program through which free-roaming cats are trapped, spayed and neutered, then returned to the outdoor locations where they were found. If those locations are deemed unsafe or otherwise inappropriate, the cats may be relocated (barn/farmyard homes are often considered ideal[1]). Kittens young enough to be socialized and friendly adult cats may be placed in shelters or foster care for eventual adoption into homes as companion animals rather than returned to the outdoors.[2]:133 Cats found suffering with terminal, contagious, or untreatable illnesses or injuries are often euthanized.[2]:124

TNR is the most widely implemented method of managing cat populations. The main goal of a TNR program is the reduction of the feral cat population; other goals may include increased adoption rates, better cat health and quality of life, and improved human-cat interactions.[3] The earliest documented practice of trap–neuter–return was in the 1950s, led by animal activist Ruth Plant in the United Kingdom.[4]:2

Terminology[edit]

TNR usually stands for trap–neuter–return. It is sometimes described as trap–neuter–release.[5] This wording appears to have been the first version of the TNR acronym.[6] The word "return" emphasizes that most feral cats are returned to their original locations under such a program. Variant acronyms and terms include TNSR (for trap–neuter/spay–return);[7] Other variations of TNVR (trap–neuter–vaccinate–return),[8] TNRM (trap–neuter–release–maintain) where "maintain" generally means caregivers feed and monitor the feral cats after they are returned to their territories;[9] and TTVAR (trap–test–vaccinate–alter–release).[10] TVHR (trap–vasectomize/hysterectomize–release) refers to a different method of cat population management, despite its similar name.[clarification needed][11]

Controversy[edit]

TNR is endorsed by the American Society for the Prevention of Cruelty to Animals (ASPCA) as "the most humane, effective and financially sustainable strategy for controlling free-roaming cat populations"[12] and "the only proven humane and effective method to manage feral cat colonies".[13] The Humane Society of the United States has also endorsed community-based TNR programs with "on-going responsible management as the most viable, long-term approach available at this time to reduce feral cat populations".[14] The American Humane Association is another supporter of TNR.[15] In Canada, the Canadian Federation of Humane Societies supports TNR, stating that the care of feral cats "is society's responsibility" as their wild nature is the result of human neglect.[16] The UK's Royal Society for the Prevention of Cruelty to Animals (RSPCA) supports "trapping and neutering of feral cats where local charities have the capacity to do so".[17] Worldwide supporters include the World Animal Foundation, based in Oneida, Kentucky,[18] and the International Companion Animal Management Coalition.[19]

Some North American wildlife organizations including the American Bird Conservancy[20] and The Wildlife Society[21] oppose TNR, disputing its effectiveness at reducing feral cat populations,[22] and claiming that free-roaming cats are responsible for much of the decline in bird populations over the last number of years, killing 1.4 to 3.7 billion birds annually in the US.[23][24][25] Rather than TNR, they recommend that free-roaming cats be taken to local animal shelters.[26][27] The Wildlife Society "support[s] and encourage[s] the humane elimination of feral cat populations, including feral cat colonies, through adoption into indoor-only homes of eligible cats and humane euthanasia of unadoptable cats".[28]

The counter-claim by TNR advocates is that cat predation is inflated.[29] They have argued that removing feral cats en masse can harm the environment and even endangered species. For example, Alley Cat Allies' "Why Removing Cats is Worse for Everyone" (2016) suggests that cats primarily prey on weak animals that would have died of disease or hunger anyway, that modern human-geographical environments include cats as part of their ecosystems and are not comparable to wilderness, and that a mass-killing of cats would create a vacuum rapidly filled by cats from other areas and the offspring of local survivors – essentially the same criticism that is leveled against TNR's own effectiveness.[30] Similarly, a 2013 Sydney Morning Herald article[31] reported on research published in the journal Global Ecology and Biogeoraph, showing that some endangered insular species of mammals in Australia were more at risk from human-introduced rats than from introduced cats, foxes, or dingoes, who keep the rat population down if these predators are not eradicated.[32] These special-case arguments do not address the broader statistics of cat predation on wildlife; in the United States alone, cats are believed to kill billions of birds and small mammals annually, though estimates vary widely, from 7.6 to 26.3 billion total.[25] TNR advocates have, in turn, criticized "anti-cat" studies as arriving at dubious predation figures based on methodological flaws.[29][33] In the United Kingdom, the Royal Society for the Protection of Birds stated that there is no evidence that cat predation "is having any impact on bird populations UK-wide".[34], in sharp contrast to American Bird Conservancy's position on the question in the US. However, the 2013 systematic review by Loss, et al., strongly supports the idea that cats have a major negative impact on small wildlife populations overall.[25]

TNR advocates also say euthanizing healthy cats is inhumane,[35] and even more expensive for public officials than TNR, because the latter "saves taxpayers money by reducing wild, free-roaming cat populations which in most cases end up in municipal shelters and have to be euthanized".[36] The No Kill Advocacy Center estimated a cost of around US$100 per cat to capture, house, and eventually euthanize the animals, and also showed significant revenue generation from adoption and licensing fees at no-kill shelters;[37] however, these revenues for are for adoptable cats, and many (perhaps most) feral animals would not qualify, and are generally returned to the urban "wild" anyway.

Research (and research criticism),[38][29][33] along with reported experience of TNR programs, are claimed by advocates to show that community cat populations indeed decline through TNR, including some colonies eventually reduced to zero.[39] However, such case-study material excludes TNR programs that failed, and it provides no data on the failure rate.

Rationales for and effectiveness of TNR[edit]

Various arguments are offered in support of TNR, and some of them have been subjected to study, with often controversial counter-claims.

Reduced population over time[edit]

TNR is often presented to policymakers as a viable alternative to capture and euthanasia.[25][40] Some long-term studies have claimed to show that TNR is effective in stopping reproduction and reducing the population over time, but scientific support for the belief that TNR is an effective means of reducing feral cat has been questioned. For example, an eleven-year study of a TNR program at the University of Central Florida achieved a population decrease of 66%, from 68 cats in 1996 (when the census was first completed after some trapping); to 23 cats in 2002.[38] No new kittens were born after 1995, and newly arrived stray or abandoned cats were neutered or adopted to homes.[38] However, this population reduction was primarily from adoption (47%) and euthanasia (11%), or simply the cats no longer living on site with their whereabouts unknown (15%),[38] and not from "releasing" the cats back to the situation they were found in.

A ten-year study of 103 colonies in Rome, Italy showed decreases within the colonies from 16% to 32%, with the highest number for colonies neutered 6 years before the study began.[41]:5 However, Natoli concluded that "This suggests that all these efforts without an effective education of people to control the reproduction of house cats (as a prevention for abandonment) are a waste of money, time and energy."[42] Population decreases are expected when at least 71% to 94% of the cats are neutered.[43]:1779 TNR advocates also frequently cite a large-scale program on 103 cat colonies in Rome. Trapping and neutering decreased the populations of 55 cat colonies there, while the other 48 colonies either gained population or stayed the same.

In many cases, TNR has resulted in colonies closing when the last remaining cat died or was adopted.[citation needed] In the United Kingdom, a TNR program at Stoke Mandeville Hospital ended with all the neutered outdoor cats having died, with none coming to take their place.[44]:522 TNR efforts in London's Fitzroy Square in the late 1970s resulted in the colony ending by 1990 with all the cats having died.[44]:522 The cat sanctuary of Parliament Hill in Ottawa, Ontario, Canada, closed in January 2013, when the four remaining cats were adopted into homes.[45] One colony had already become extinct and another was approaching extinction within two years, in a study of 12 colonies in rural North Carolina.[46]:1363

TNR efforts may be hampered if colony locations are made public. An early 2003 study by Castillo of two colonies in popular public parks of Miami-Dade County, Florida revealed that highly visible, well-fed cat colonies attracted illegal abandonment of additional cats, including numerous kittens and females with litters.[47]:252[48]:1358 Despite dedicated efforts to trap and remove the newcomers as well as trap the existing cats, there was a slight increase in population from 81 to 88 cats over the year studied.[47]:251[48]:1358 Community strategies to reduce abandonment in general include providing low cost spaying and neutering for owned cats;[41]:5 improved pet retention programs, and expansion of no-kill animal sheltering.[48]:1358

Life versus death[edit]

The typical outcome for a feral cat taken to a traditional shelter which does not practice no-kill sheltering is euthanasia (i.e., humanely putting the animal to death).[35] This is often the outcome for timid or even friendly stray cats as well;[35][48]:1357 a study identified euthanasia in shelters as the leading cause of death of cats.[48]:1359

Since Santa Clara County, California began TNR in 2011, the county reported that "Thanks to this program, the shelter saw a 15% reduction in cat intake and an amazing 65% reduction in cat euthanasia."[49] In a TNR program in Orange County, Florida, the numbers of cats euthanized decreased 18% in a six-year period after starting TNR.[50]:292

Quality of life[edit]

TNR programs improve the welfare of the cats involved in many ways. They prevent the birth of kittens, who would be at risk of an early death in the wild.[48]:1359 Adult female cats are no longer burdened with cycles of repeatedly giving birth to and caring for kittens while fending for themselves.[51] Medical conditions such as infections, dental issues, and flea treatments are attended to when the cats are neutered.[2]:115 Spaying and neutering also increases their life expectancy;[52]:35 the cats are no longer subject to certain cancers,[51] and the chances of being hit by a car or injured in a fight drop a great deal.[53]

When programs provide for feral kittens to be socialized and adopted, and for friendly cats to be adopted, the welfare of those cats is improved.[2]:133 Cats returned to their original location are fed, monitored and receive ongoing care from caregivers; including being re-trapped if further medical needs arise.[54] Their health measurably improves, as they gain weight after being neutered,[55]:212 while having ample opportunity for exercise.[55]:210 One study suggests that although TNR "may not meet the gold standard of care desired for pet cats, it appears that sterilized feral cats can enjoy an extended period of good quality of life".[48]:1359

Fewer complaints[edit]

Neutering cats makes them less likely to roam, spray urine and fight; resulting in fewer nuisance complaints.[56]:16 After starting a TNR program in December 1995, Orange County, Florida received fewer complaints about cats, even after broadening the definition of a nuisance complaint.[50]:296 A TNR program at Texas A&M University in 1998-2000 resulted in fewer complaints, showing that the remaining cats were less of a nuisance than they were previously.[56]:25

Cost savings[edit]

While neutering cats is costly, euthanizing them costs more.[57]:8 In Orange County, Florida, the average cost of impounding and euthanizing a cat was $139; while the average cost of surgery was $56.[50]:294 With 7,903 feral cats neutered over 6 years starting in December 1995, the county saved $656,000.[50]:295

In Port Orange, Florida a TNR program started in 2013 in the city's business areas resulted in fewer stray cats and money saved.[58] In the first year, 214 cats were sterilized for $13,000, which was much less than over $50,000 spent in 2010, when most of the impounded cats were euthanized.[58] A further estimated $123,000 was saved for not having to impound the offspring of the now spayed cats.[58]

Improved morale and public support[edit]

TNR programs are able to garner stronger public support than programs that result in euthanasia.[59]:49 In 2007, Alley Cat Allies commissioned a survey by Harris Interactive, which found that Americans overwhelmingly (81%) considered it more humane to leave a stray cat outside to live out his life rather than having the cat caught and killed.[60]:1 The number was still high (72%) if the person knew that the cat would die when hit by a car in two years' time[60]:2 (although the chances of being hit by a car are much less when a cat is neutered.)[53]

In London-area hospitals in the UK, patients resisted attempts to trap feral cats for euthanasia, but took a great interest in TNR programs; even offering to pay the veterinary fees out of their own pocket money.[44]:521 A TNR program in San Quentin State Prison in California, replacing the practice of euthanizing 100 to 250 cats each year, resulted in benefits to the inmates and staff, including "less violence and tension as well as being able to 'model relatedness' to other species and individuals".[59]:51

In Orange County, Florida, a TNR program started in December 1995 improved the morale of everyone involved; citizens "who previously felt overwhelmed by the dilemma of feral cats they saw in their neighborhoods now feel empowered and able to make a difference in these cats' lives".[50]:297 At the same time, county animal services staff and citizens concerned about the cats were described as viewing each other "with a new perspective and understanding rather than as adversaries".[50]:297

Alternatives claimed to be ineffective and inhumane[edit]

Doing nothing can result in the numbers of feral cats increasing. A study of six managed colonies in rural North Carolina showed a 36% decline in population over two years, while three control colonies without TNR increased by 47% on average.[46]:1363 Further, animal welfare problems such as high rates of kitten mortality continue to occur.[46]:1362 A 2005 paper by the Humane Society Institute for Science and Policy suggested that "While still fairly common, this is not a responsible or constructive choice."[59]:48

Removal is an alternative to TNR control their population.[43]:1780 Eradication programs "often require years to accomplish and hundreds of hours of work and are only successful in closed populations where no new cats can arrive".[59]:48 Further, methods used often involve poisoning, shooting, hunting, and other methods considered animal cruelty in many North American jurisdictions.[61][62] Trapping and removal of cats by euthanasia has been used in many communities, but almost never results in a permanent decrease in the cat population.[59]:48[better source needed] The 2005 Human Society review stated: "It is extremely difficult to remove every cat in a particular location, and most locations are not sufficiently isolated to prevent migration of new cats into the ecological vacuum created by cat removal. If there is sufficient food and shelter, new cats will move in from nearby areas, and survivors of the removal program will continue to reproduce until the maximum carrying capacity is reached again."[59]:48 Many local and sub-national governments have turned to TNR believing it to be a more effective and humane approach to control feral cat populations.[63]:11[49][58]

Effect on wildlife[edit]

The trap–neuter–return approach is controversial. Some wildlife and bird advocacy organizations argue that TNR does nothing to address the possibility that predation by feral cats could threaten endangered species. TNR groups state that the effect of habitat destruction is caused by irresponsible human development and not by feral cat colonies. A 2013 systematic review by Scott R. Loss, et al., in Nature Communications countered that all sources of population decline in a threatened species are detrimental to its survival.[25] Further, feral cats are now thought to be the single largest cause of anthropogenic bird mortality in North America.[25]

Longcore et al. found that feral cats harm wildlife on continents as well as islands, and that there have been recorded instances of bird extinction from feral cats on islands. Their paper also argues that fragmented ecosystems near urban areas are similar to islands and more susceptible to feral cat damage, and that feral cats in urban areas also pose significant risk to migratory birds. The authors argue that feral cats are exotic and do not fill an existing niche and that even well-fed cats significantly impact on wildlife. The article details population and comparative studies of the adverse effects of feral and free roaming cats on birds and other wildlife. However, longer and more detailed studies need to be done on this subject. The authors also argue that feral cats act as vectors for diseases that can impact domestic cats, wildlife and humans, examples include feline leukemia virus, feline immunodeficiency virus, fleas and ear mites (which are also carried by canines and wildlife), hookworms, roundworms, Bartonella, Rickettsia, Coxiella and Toxoplasma gondii, and that fecal matter has also been shown to degrade water quality.[64]

In the UK, The Royal Society for the Protection of Birds states that there is no scientific evidence that cat predation "is having any impact on bird populations UK-wide. This may be surprising, but many millions of birds die naturally every year, mainly through starvation, disease, or other forms of predation. There is evidence that cats tend to take weak or sickly birds ... Those bird species that have undergone the most serious population declines in the UK (such as skylarks, tree sparrows and corn buntings) rarely encounter cats, so cats cannot be causing their declines. Research shows that these declines are usually caused by habitat change or loss, particularly on farmland."[34] This evidence is despite the common practice in the UK of allowing cats access to the outdoors,[65] which is recommended to prevent feline obesity,[66]:138 and behavior problems and other health problems arising from confinement stress.[66]:121

British biologist Roger Tabor states that "studies from all around the world have found that cats catch relatively few birds compared to small mammals".[66]:135 Moreover, city cats have smaller ranges; in his research, Tabor found "the average annual catch of the average London cat to be two items instead of the fourteen of a village cat".[66]:135 Tabor comments about some of the challenges of stalking birds for cats: "From the cat's point of view not only do birds not play fair by flying and having eyes that can see beyond the back of their heads, but they can positively cheat by using loud alarm calls and throw the cat's chances of catching any others."[67]:123

This study has limited applicability to North American birds and wildlife, however. Cats are a domesticated species that did not exist in North and South America prior to European contact.

Methodology[edit]

The first trigger for a trap–neuter–return program is when free-roaming cats or kittens are seen in need, or not having been neutered. A TNR program approaches the situation using the following recommended steps:

Preparation[edit]

  1. Assessment of the cats and their environment, including whether they appear to be stray pets or feral animals; whether there are kittens and/or nursing mothers, and any ill or injured cats. This helps to plan ahead for the care to be provided after trapping.[68]:6
  2. Communication with neighbors and any caretakers, and building of good community relations, working to address the concerns of others.[68]:5[69][2]:16
  3. Establishing a regular feeding schedule. This may involve providing feeding stations and winter shelters.[68]:7[2]:13
  4. Securing a holding/recovery area where the cats can wait for surgery (if not immediate) and recover after surgery.[68]:11[2]:14
  5. Finding and coordinating with a veterinarian or clinic to perform the surgery and provide other medical treatment.[68]:7
  6. Assembling trapping supplies, including humane traps, newspapers and other useful materials.[68]:11[2]:68
  7. Withholding food (but not water) for about 24 hours before trapping, with the cooperation of caregivers and neighbors.[68]:14

Trapping[edit]

  1. Baiting and setting the traps in a safe location, using as many traps as there are cats in the colony needing trapping.[2]:67
  2. Waiting nearby but out of sight for cats to enter the traps and the traps to close.[68]:15[2]:75
  3. Quickly covering each occupied trap with a cover or sheet, which helps to calm the cat within.[68]:15[2]:76
  4. Checking whether each trapped cat is already owned or neutered (e.g., via ear-tip marking, identification tattoo or microchip, and lost-pet databases and ads; attempting to contact owners in the case of stray pets.[70]
  5. Carefully releasing any accidentally trapped wildlife.[2]:88
  6. Safely transporting the cats in their traps to the clinic or holding area.[68]:16
  7. Trying alternative traps and methods in the case of unusually wary cats.[2]:91[71]

Neutering, medical care and socialization[edit]

  1. Providing extra care for cats not yet ready for surgery. Cats in poor condition may receive additional medical attention, and be well-fed to gain weight and strength before surgery.[2]:109 Young kittens may be socialized in foster care, which prevents their becoming feral.[72] Nursing mother cats may be kept with their kittens (and even other orphaned kittens)[73] until the kittens are weaned.[74][75]
  2. When ready, a veterinarian performs spay or neuter surgery and provides other medical attention as needed.[76] Multiple surgeries may be done in high volume clinics.[77]
  3. During the surgery of feral cats, ear-tipping (removing 3/8 inch or 1 cm from the tip of the left ear; proportionally smaller in a kitten) identifies that the cat has been neutered and treated, when later seen from a distance.[78]
  4. Vaccinations are provided as arranged in advance. Common vaccines include rabies,[79], FVRCP, panleukopenia ("distemper"), and respiratory-virus vaccines,[80], though this will vary by program.
  5. Cats found suffering with terminal or untreatable illnesses or injuries are humanely euthanized.[81]
  6. When the vet deems that the cats are ready to leave the clinic, they are taken to the recovery area, and monitored for at least 24 hours.[68]:17[82]
  7. If needed, the cats may receive additional care (e.g., medications, or more recovery time from complex surgery such as amputation).[2]:109[83][84]

Returning the cats[edit]

  1. If the original colony location is safe, the treated cats are transported there and safely released from their traps or carriers.[68]:18
  2. If the location is not safe for feral cats, other arrangements are made, e.g. for farmyard homes.[2]:127[85]
  3. Tame cats and (especially) kittens are placed in foster care until they are adopted.[86] If there are insufficient resources to foster or shelter, the cats may be returned to outdoor colony locations in the same manner as feral cats.[87]
  4. Detailed records are kept of the cats assisted,[68]:5 and the traps and other materials used are regularly cleaned.[82]
  5. Caregivers monitor the outdoor colony locations, providing food, shelter, and medical care, and watch for any new abandoned cats requiring trapping.[54] Some communities with "feral freedom" programs return cats without ongoing monitoring by caregivers.[87]

Early in TNR work, some groups did routine testing for the feline leukemia virus (FeLV) and the feline immunodeficiency virus (FIV) prior to the neutering surgery. This practice is no longer recommended, due to problems such as unreliable results, the high cost of testing, and the low incidences of the viruses.[2]:120[88]

TNR programs by country[edit]

The legal status of community cats varies from location to location, as do the histories of TNR programs in different places. Allie Phillips, director of the National Center for Prosecution of Animal Abuse in the United States, states that stray and feral cats are often viewed with less sympathy than pet animals, and less worthy of legal protections.[61]

British Virgin Islands[edit]

In 1986, AnnaBelle Washburn worked with Tufts University's School of Veterinary Medicine to sterilize feral cats on Virgin Gorda in the British Virgin Islands, "in one of the earliest partnerships between veterinary medicine and grass-roots organizations to improve the lot of feral cats".[59]:44

Canada[edit]

In Canada, it is an offence under the Criminal Code to intentionally cause unnecessary pain, suffering or injury to an animal.[62] Poisoning animals is specifically prohibited.[62][89] It is also an offence to threaten to harm an animal belonging to someone else.[90] Most provinces and territories also have their own animal protection legislation.[91]

Canada's best-known TNR effort was at the Cat Sanctuary of Parliament Hill in the nation's capital, Ottawa, Ontario, where cats were employed for pest control until 1955.[92] Various people fed the remaining cats until 1970, when Irene Desormeaux began feeding them at their eventual colony location.[93] In the mid 1980s, Rene Chartrand built wooden housing for the cats and helped with their care, taking over when Desormeaux died in 1987.[93] In 1997 other volunteers joined in, and the structures were rebuilt.[93] In a brutal winter, "the cats survived marvellously cuddling up four or five at a time in the condos".[94] However, neutering all the cats only occurred in the last ten to fifteen years of the sanctuary's operation.[95] In 2013, the colony closed when the last four cats were adopted into homes.[95]

In 1989, Carol Reichert founded the Richmond Animal Protection Society (then Richmond Homeless Cats), to help feral cats in Richmond, British Columbia.[96][97] Soon 43 feeding stations were being tended in Richmond and south Vancouver.[96] In 1999, space was donated for a shelter,[96] which became Canada's largest cat sanctuary, including space for cats with feline leukemia and feline AIDS.[98] The organization worked to spay and neuter many animals and worked to prevent pets from entering shelters.[96] Determined to "end needless euthanasia", the organization made a successful bid for the city's animal control contract, and in 2007, "implemented a no-kill policy for the animals regardless of age, medical needs or adoptability".[96]

In 2000, Maria Soroski and Karen Duncan founded the Vancouver Orphan Kitten Rescue Association (VOKRA) in Vancouver, British Columbia.[99] They first planned to care for very young, mainly bottle-feeding kittens, who rarely survived if found without a mother cat.[100] They soon found that older kittens would do better in foster care, and then included mother cats, both tame and feral.[100] Care provided to feral cats includes caring for pregnant feral mothers through birthing and until their kittens are weaned.[100] By 2014, the organization had grown to over 350 foster homes helping 1,800 cats annually.[99] Soroski said they had "virtually eliminated feral cat colonies in Vancouver and Burnaby", and had recently begun the same work in Surrey.[99]

In 2005, Pierre Filitreault began helping feral cats at a Halifax, Nova Scotia dockyard on a Canadian Armed Forces base.[101] Disappointed with what happened with two starving kittens he took to a shelter, he set up a TNR program, forming Pierre's Alley Cat Society in 2007.[101] The Department of National Defense paid to have the cats neutered.[102]

Official response has not always been positive. In January 2012, a bylaw officer in Merritt, British Columbia, removed cat food and asked the Royal Canadian Mounted Police to consider criminal charges against those feeding the community cats.[103] One op-ed writer complained that "Taking food away, particular in the dead of winter, only exacerbates the problem by encouraging the cats to forage for food in a wider area. And ultimately, starvation can occur, which again, is considered neglect, and certainly could worsen the City's reputation."[104] No charges were laid, but the rescue group's business license was revoked and it was forced to move from its storefront location.[105]

The City of Toronto, Ontario, has included TNR in its animal services for some years, and enacted a bylaw specifically addressing TNR in 2013.[106] Toronto Animal Services offers spay and neuter clinics for feral cats,[107] and is a member of the Toronto Feral Cat Coalition.[108] Other governments within Canada with laws or policies supporting TNR are described in the list of governments supporting trap–neuter–return.

Denmark[edit]

TNR was practiced in Denmark in the mid-1970s, as reported at the 1980 UFAW symposium in London.[4]:3 The Danish Cat Protection Society developed the practice of both tattooing and ear-tipping the ear of the neutered cats to identify them.[67]:187

France[edit]

In 1977, Michel Cambazard began to advocate for free-living cats at the Montmartre Cemetery in Paris, where the cats were routinely euthanized. In 1978, the city issued a Declaration of Rights of the Free-living Cat.[109] In that year, Cambazard founded École du Chat and TNR'd its first cat, continuing to help thousands of cats in the following years.[110]

Greece[edit]

In the 1980s, the Greek Animal Welfare Fund initiated the neutering of stray cats in Athens, supported by individuals in the UK.[44]:522 The organization continues to be active, organizing a mass neutering drive for stray cats in Athens for October 2014.[111]

Hong Kong[edit]

In 2000, the Hong Kong SPCA began a TNR program, called a Cat Colony Care Program (CCCP), in Hong Kong.[112] In 2014, the organization's website reported a reduction in euthanasia from 40,000 cats in 1963 to 5,000 cats annually.[113]

Italy[edit]

Soon after visiting Venice, Italy, in 1965, Helena Sanders and Raymonde Hawkins initiated a program offering veterinary help, often for neutering, to assist cat caretakers there.[4]:48 After initial resistance from local animal protection societies, neutering schemes for city cats were accepted in many parts of Italy.[4]:48 The cats of Venice and Rome became famous as a result of the publicity given to their neutering programs.[44]:523

Since 1988, killing feral cats has been illegal in the Latium Region, which includes Rome. Since August 1991, feral cats have been protected throughout Italy when a no-kill policy was introduced for both cats and dogs.[41] Feral cats have the right to live free and cannot be permanently removed from their colony; cat caretakers can be formally registered; and TNR methods are outlined in the national law on the management of pets.[41]

Japan[edit]

In the 1990s a TNR program was started in Shiga Prefecture by Susan Roberts and David Wybenga of the Japan Cat Network (JCN). The JCN has also assisted with other TNR programs.[114]

South Africa[edit]

In the mid-1970s, Louise Holton worked with the Johannesburg SPCA on TNR programs in that city.[115] In 1991, Adele Joffe founded Friends of the Cat, a TNR organization in Johannesburg.[116] Holton continued to help feral cats in South Africa as part of her outreach efforts with Alley Cat Rescue, founded in 2001.[117]

United Kingdom[edit]

The earliest documented practice of trap–neuter–return was in the 1950s, led by animal activist Ruth Plant in the UK.[4]:2 In the mid-1960s, former model Celia Hammond gained publicity for her TNR work[4]:2 "at a time when euthanasia of feral cats was considered the only option".[118] Hammond "fought many battles with local authorities, hospitals, environmental health departments" but stated that she succeeded over the years in showing that control "could be achieved by neutering and not killing".[118]

In 1975, Ruth Plant[4]:2 founded the Cat Action Trust to help feral cats using TNR.[119] From 1978 to 1979, biologist Roger Tabor mapped the distribution of 153 known feral cat colonies in central London, some being managed by the Cat Action Trust.[67]:91

In 1980, the Universities Federation for Animal Welfare (UFAW) organized the first international scientific symposium on "The Ecology and Control of Feral Cats" in London, where TNR experiences in the UK and Denmark were documented.[4]:2 The symposium was considered a "watershed occurrence" where attitudes toward feral cats began to shift toward humane treatment. In 1982, UFAW published a booklet promoting TNR: Feral Cats: Suggestions for Control.[4]:6

The Cat Action Trust reports that many thousands of feral cats have been neutered in subsequent years.[119] In 1986, Hammond founded the Celia Hammond Animal Trust to continue her work with feral cats, taming and rehoming hundreds of feral kittens each year;[120] and offering low cost neutering, which by 2014 was reported to have sterilized nearly 400,000 cats.[118]

In 2008, the Scottish Wildcat Association began utilizing trap–neuter–return as a way to prevent hybridisation between feral cats and the regionally endangered Scottish wildcat, as part of the Wildcat Haven project.[121] In 2014 they announced over 250 square miles of remote wildcat habitat was now effectively feral cat free[122] through neutering the feral population, farm cats, and pets with the support of the local community and local welfare groups.

United States[edit]

In a January 2013 legal brief, Alley Cat Allies provided evidence that at least 240 municipal or county governments in the United States had enacted ordinances supporting TNR; a ten-fold increase from 2003.[63] New Jersey, California and Texas had the highest number of local ordinances.[63] New York City-based organization Neighborhood Cats has cataloged local ordinances in 24 US states.[123] Model ordinances are available from Neighborhood Cats,[123] Alley Cat Allies,[63] and the No Kill Advocacy Center.[124] Many US communities with ordinances favorable toward TNR are described in the list of governments supporting trap–neuter–return.

TNR dates back to the late 1960s in the US.[125] In approximately 1970, a group in Ocean County, New Jersey began its efforts.[4]:7 In 1984, AnnaBelle Washburn introduced TNR to Martha's Vineyard, Massachusetts.[126]

In 1989, Nathan Winograd and others formed the Stanford Cat Network to assist about 1,500 cats at Stanford University in California, in probably the first formal American university campus TNR program, at Stanford University.[59]:44[127] Within 15 years, the population at Stanford had dropped to 85 cats.[59]:44 By 1990, other groups were also practicing TNR in Idaho, Nevada, Pennsylvania, and Colorado.[4]:7

In 1990,[128] Louise Holton and Becky Robinson discovered an alley with 56 cats and two smaller colonies in Washington, DC, and neutered all the cats.[4]:8 Deluged by requests for help,[4]:8 and concerned for cats routinely being killed by animal control agencies and shelters, Holton and Robinson founded Alley Cat Allies.[129] They developed extensive educational materials, and organized national conferences beginning in 1994.[4]:9 They started a Feral Friends Network, which has a global reach.[130] The organization grew to 500,000 supporters and a staff of over 40 in 2014.[131] Holton left in 2001 to found Alley Cat Rescue.[128]

In the 1990s, a number of programs to help feral cats were initiated. In 1992, San Diego's Feral Cat Coalition developed the first high-volume feral cat sterilization program, where up to 150 cats were sterilized in a single day with the help of volunteer veterinarians and other volunteers.[59]:44[132][133] Other communities followed, including Operation Catnip in Raleigh, North Carolina in 1997,[134] and Operation Catnip in Alachua County, Florida in 1998.[135] In 1993, led by Richard Avanzino,[136]:10 the San Francisco SPCA started a Feral Cat Assistance Program, offering free sterilization, advice and supplies to cat caretakers.[59]:44 The program was one of several reforms to create a no-kill community.[137]:180 In 1994, PetSmart Charities began to provide grants toward sterilization programs for free-roaming cats and other animals; the organization's website stated in 2014 that more than 2 million spay or neuter surgeries have been funded.[138] In 1995, the Doris Day Animal League (DDAL) created the first annual "Spay Day USA"[139] on the last Tuesday of each February, which continues to help many feral cats and other animals as World Spay Day[140] after the DDAL's merger with the Humane Society of the United States in 2006.[141]

TNR efforts in the US have also encountered opposition. Traditional shelters often disagreed with TNR, including the Humane Society of the United States,[137]:68 which later reversed its position.[142] The majority of traditional shelters continue to euthanize feral cats.[35] Some wildlife groups blame cats for much of the reduction in US bird populations; one such is the American Bird Conservancy, which began "Cats Indoors" campaign in 1997.[4]:18[143] TNR has gained increasing support over the years.[63]

The Feral Cat Coalition of Oregon purchased a mobile clinic in 1998,[59]:44 which by August 2014 had neutered 70,000 cats.[144]

In 1999, Maddie's Fund (also known as Maddie's Institute), the family foundation of Dave Duffield and his wife Cheryl,[136]:8 began to provide grants for large-scale neutering of feral cats. Between July 1999 and May 2002, 170,000 cats were neutered by over 1,000 veterinary members of the California Veterinary Medical Association in a $12 million project.[38]:42 Other programs were added, such as low cost sterilization,[136]:3 and research on shelter medicine;[136]:6 with the goal of helping to build a no-kill nation.[136]:3 Maddie's Fund remains one of the more active pro-TNR organizations in the United States, with a stated goal of a "no-kill nation".[136]:1

On October 16, 2001, Alley Cat Allies created the first annual National Feral Cat Day on the 10th anniversary of its incorporation[4]:8 "to raise awareness about feral cats, promote trap–neuter–return, and recognize the millions of compassionate Americans who care for them".[145] The event has attracted international participants.[145]

In 2001, under the leadership of Nathan Winograd, Tompkins County, New York, became the first no-kill community in the US,[137]:180[146] "saving 100 percent of healthy and treatable animals, and 100 percent of feral cats".[137]:180 In the No Kill Equation, a "roadmap to no kill"[147] developed by Winograd, TNR is one of the essential elements.[148]:4 Many communities followed this strategy in subsequent years.[149]

In 2008, a grant from Best Friends Animal Society supported a feral freedom program in Jacksonville, Florida, that saw the end of killing stray and feral cats in that city.[150][87] The program, conceived by Rick Ducharme of First Coast No More Homeless Pets, "has feral cats trapped by Jacksonville Animal Control bypass the shelter entirely in favor of being spayed or neutered and returned to the location where they were trapped."[151] Similar programs were later implemented in Albuquerque, New Mexico,[151] DeKalb County, Georgia,[151] San Antonio, Texas,[152] Baltimore, Maryland,[152] Salt Lake City, Utah,[153][154] Philadelphia, Pennsylvania[155] and many other communities.[156]

In Palm Beach County, Florida, a project called Project CatSnip: Countdown to Zero (C2Z, for short) was organized in 2015 as a collaboration between government agencies, businesses, volunteers from a local animal rescue group, and residents working together to end euthanasia of feral cats in the community through TNR, toward a goal of zero cats euthanized in the county by 2024.[157]

Governments sometimes have been sued to try to block their TNR efforts. In December, 2010, an injunction was granted to prevent a planned TNR program of the City of Los Angeles until an environmental review was completed under the California Environmental Quality Act.[158] The judge did not rule on any environmental issues, or prohibit other organizations from doing TNR in the city.[159]

Some cat caretakers have been prosecuted for taking care of feral cats, where local ordinances did not allow for their activities. In 2011, charges against Danni Joshua of Vandercook Lake, Michigan for "allowing animals to run loose" were dismissed when she agreed to have her colony of 15-20 cats relocated.[160] In 2012, 78-year-old Dawn Summers was sentenced to community service for hoarding, as she was feeding up to 27 community cats within a managed colony in a city-sanctioned program in Biloxi, Mississippi.[161] Alley Cat Allies criticized the decision, stating that the community cats should not have been considered owned by the caregiver.[162] The Virginia Supreme Court found a zoning ordinance overbroad in 2013, when Henrico County charged Susan Mills for caring for feral cats, which the county said was not a permitted activity under the zoning. A circuit court judge had ordered her to stop feeding the cats, but that part of the decision was not enforceable.[163]

Opponents of feral cats have also been prosecuted for trying to harm or kill the animals, contrary to animal-protection laws. In 2007, Jim Stevenson stood trial for shooting a cat from a colony in Galveston County, Texas.[164][61] Stevenson observed the colony cats hunting endangered piping plovers in the area.[164] The trial resulted in a hung jury because of a gap in the law stating that ownership of the animal had to be proven, an issue which has since been resolved.[61] In December 2011, wildlife biologist Nico Dauphiné received a suspended sentence for attempting to kill feral cats with rat poison in Washington, DC,[165]
