Trap-neuter-return (TNR) is a program through which free-roaming community cats (not belonging to particular humans)[1] are humanely trapped; sterilized and medically treated; and returned to the outdoor locations where they were found. If those locations are deemed unsafe or otherwise inappropriate, feral cats (unsocialized to humans) are relocated to farmyard homes.[2] Kittens still young enough to be socialized, and friendly adult cats, are typically placed in foster care for eventual adoption into homes as companion animals, rather than returned to the outdoors.[3] Cats found suffering with terminal or untreatable illnesses or injuries are humanely euthanized.[4]

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" [5] and "the only proven humane and effective method to manage feral cat colonies."[6] The Humane Society of the United States has also endorsed "community-based Trap-Neuter-Return (TNR) programs with on-going responsible management as the most viable, long-term approach available at this time to reduce feral cat populations."[7] The American Humane Association is another supporter of TNR.[8] 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.[9] The U.K.'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."[10] Worldwide supporters include the World Animal Foundation, based in Oneida, Kentucky,[11] and the International Companion Animal Management Coalition.[12]

North American wildlife organizations including the American Bird Conservancy,[13] The Wildlife Society[14] and others including the American Veterinary Medical Association,[15] oppose TNR. They dispute its effectiveness at reducing feral cat populations,[16] and claim 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 U.S.[17][18][19] Rather than TNR, they recommend that free-roaming cats be trapped and taken to local animal shelters[20] or humanely killed.[21] The Wildlife Society is more open about recommending killing of cats in their position statement: "Support and encourage 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."[22]

TNR advocates counter that cat predation is inflated, based on unscientific studies that extrapolate from tiny samples and project them onto whole nations.[23] They point out that removing feral cats en masse can harm the environment and even birds;[24] killing healthy cats (the usual result if feral cats are taken to animal shelters)[25] is inhumane, and even more expensive for public officials than TNR;[26] and research[27] and experience[28] of TNR shows that community cat populations indeed decline. In the U.K., The Royal Society for the Protection of Birds states that there is no evidence that cat predation "is having any impact on bird populations UK-wide".[29]

TNR is sometimes described as trap-neuter-release, changing the last word of the acronym.[30] This wording appears to have been the first version of the TNR acronym.[31] The word "return" emphasizes that most feral cats are returned to their original locations under this program, and is the word most in current use. Some programs also go by other acronyms: TNVR (trap-neuter-vaccinate-return) adds emphasis to the process of vaccinating the cats for diseases like rabies before their return to the outdoors.[32] TNRM (trap-neuter-release-maintain) adds the word "maintain," emphasizing the final part of the program, where caregivers feed and monitor the feral cats after they are returned to their territories.[33] TTVAR (trap-test-vaccinate-alter-release) adds details about testing undertaken for serious illnesses, but this acronym is not in wide usage.[34]

Methodology[edit]

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

Preparation[edit]

  1. Assess the cats and their environment.[35] Do they appear to be stray or feral; are there kittens and/or nursing mothers; are there ill or injured cats? Plan ahead for the care to be provided after trapping.[36]
  2. Communicate with neighbours and any caretakers. Build good community relations, working to address the concerns of others.[37]
  3. Establish a regular feeding schedule. This may involve providing feeding stations and winter shelters.[38]
  4. Secure a holding/recovery area where the cats can wait for surgery (if not immediate) and recover after surgery.[39]
  5. Find and coordinate with a veterinarian or clinic to perform the surgery and provide other medical treatment.[40]
  6. Assemble trapping supplies, including humane traps, newspapers and other useful materials.[41]
  7. Withhold food (but not water) for about 24 hours before trapping, with the cooperation of caregivers and neighbours.[42]

Trapping[edit]

  1. Bait and set the traps in a safe location, using as many traps as there are cats in the colony needing trapping.[43]
  2. Wait patiently nearby but out of sight, for cats to enter the traps and the traps to close.[44]
  3. Quickly cover each occupied trap with a cover or sheet, which helps to calm the cat within.[45]
  4. Check whether each trapped cat is already owned or neutered (ear tip; identification tattoo or microchip; lost pet databases and ads), and take appropriate action.[46]
  5. If trap occupants are wildlife, carefully release them.[47]
  6. Safely transport the cats in their traps to the clinic or holding area.[48]
  7. If a cat is too fearful or savvy of the regular box trap, try alternate traps and methods.[49]

Neutering: Medical care and socialization[edit]

  1. Provide extra care for cats not yet ready for surgery. Cats in poor condition may need to receive medical attention, gain weight and strength before surgery.[50] Young kittens may be socialized in foster care, which prevents their becoming feral.[51] Nursing mother cats may be kept with their kittens (and even other orphaned kittens)[52] until the kittens are weaned.[53] "Kittens can be safely spayed or neutered at eight weeks, or as soon as they weigh two pounds (and are healthy)."[54]
  2. When ready, a veterinarian performs spay or neuter surgery and provides other medical attention as needed.[55] Multiple surgeries may be done in high volume clinics.[56]
  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.[57]
  4. Vaccinations are provided as arranged in advance. Common vaccines include rabies[58] and FVRCP, "the 'distemper' (panleukopenia) and respiratory virus vaccine".[59]
  5. Cats found suffering with terminal or untreatable illnesses or injuries are humanely euthanized.[60]
  6. When the vet deems that the cats are ready to leave the clinic, transport them to the recovery area, and monitor them for at least 24 hours.[61]
  7. If needed, provide further nursing care (e.g. administering medications; providing recovery time from more complex surgery such as amputation).[62]

Returning: The cats go home[edit]

  1. If the original colony location is safe, transport the feral cats there and safely release them from their traps or carriers.[63]
  2. If the location is not safe for feral cats, make other arrangements for farmyard homes.[64]
  3. Keep tame cats and kittens in foster care until they are adopted.[65] 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.[66]
  4. Keep detailed records of the cats assisted,[67] and clean the traps and materials used.[68]
  5. Caregivers monitor the outdoor colony locations, providing food, shelter, and medical care, and watching for any new abandoned cats requiring trapping.[69] Some communities with "Feral Freedom" programs return cats without ongoing monitoring by caregivers.[70]

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 incidence of the viruses.[71]

Legal issues[edit]

The legal status of community cats varies from location to location.

Italy[edit]

Since 1988, killing feral cats has been illegal in Rome, Italy, and 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.[72] Feral cats have the right to live free and cannot be moved from their colony; cat caretakers can be formally registered; and TNR methods are outlined in the national law on the management of pets.[72]

USA[edit]

In a January 2013 legal brief, Alley Cat Allies found that at least 240 municipal or county governments in the U.S.A. had enacted ordinances supporting TNR; a ten-fold increase from 2003.[73] New Jersey, California and Texas had the highest number of local ordinances. New York City-based Neighborhood Cats has found local ordinances in 24 states, and provided copies of the relevant sections on their website.[74] Model ordinances are available from Neighborhood Cats,[74] Alley Cat Allies,[75] and the No Kill Advocacy Center.[76]

Some U.S. communities that now have ordinances and/or policies supporting TNR include:

Sometimes governments 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.[91] The judge did not rule on any environmental issues or prohibit other organizations from doing TNR in the city.[92]

Sometimes cat caretakers have been prosecuted for taking care of their colony cats, where local ordinances did not allow for their activities:

  • In 2013, the Virginia Supreme Court found a zoning ordinance overbroad 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.[93]
  • 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.[94] Alley Cat Allies criticized the decision, stating that the community cats should not have been considered owned by the caregiver.[95]
  • 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.[96]

Sometimes animal abusers are prosecuted for trying to harm or kill cats or kittens contrary to animal protection laws:

  • In December 2011, wildlife biologist Nico Dauphiné received a suspended sentence for attempting to kill feral cats with rat poison in Washington, D.C.[97]
  • In 2007, bird enthusiast Jim Stevenson stood trial for the witnessed shooting and painful death of Mama Cat, one of several killed cats being cared for by a caretaker in Galveston County, Texas.[98][99] Stevenson believed the colony cats were hunting the endangered piping plover in the area.[98] 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.[99]

Allie Phillips, director of the National Center for Prosecution of Animal Abuse, states that stray and feral cats are often seen as unsympathetic, and less worthy of the legal protection which they merit.[99]

Canada[edit]

The City of Toronto, Ontario, has included TNR in its animal services for some years, and enacted a bylaw specifically addressing TNR in 2013.[100] Toronto Animal Services offers spay and neuter clinics for feral cats,[101] and is a member of the Toronto Feral Cat Coalition.[102] Some other governments in Canada with laws and/or policies supporting TNR include:

British Columbia[edit]

Ontario[edit]

Quebec[edit]

Nova Scotia[edit]

Less positive were Merritt, British Columbia officials, when in January 2012, a bylaw officer removed cat food and asked the Royal Canadian Mounted Police to consider criminal charges against those feeding the community cats.[117] One 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."[118] No charges were laid, but the rescue group's business license was revoked and they were forced to move from their storefront location.[119]

Cruelty laws[edit]

In Canada, it is an offence under the Criminal Code to intentionally cause unnecessary pain, suffering or injury to an animal.[120] Poisoning animals is specifically prohibited.[120][121] It is also an offence to threaten to harm an animal belonging to someone else.[122] Most provinces and Territories also have their own animal protection legislation.[123]

Rationale[edit]

Supporters of TNR embrace this practice as part of a "no-kill" philosophy. Euthanasia on a massive scale is not fiscally practical. TNR advocates agree that the traditional methods of trapping-and-removing will not work because of a "vacuum effect": As some cats are taken out of their territory, others will move in to replace them, which renders the initial removal ineffective.[124] However, there is little to no scientific evidence to support this claim.[citation needed] If other feral cats are available to do so, the primary factor of whether they will or not is the availability of food: If enough food is present, then any nearby cats may move in.[125] This, however ignores one simple fact. The food supply for most "community cats" is food provided to them by people. If people are prevented from feeding free roaming cats, there will be nothing to attract other cats to replace those removed.[citation needed]

Effectiveness[edit]

Studies have been conducted to gauge the effectiveness of TNR. Several of them suggest that the procedure works.[126][127][128] A PhD study in North Carolina found that TNR consistently reduced the populations of feral cat colonies by a mean of 36% over two years and with the extinction of one third of the colonies within the same period, while the non-TNR'd colonies increased by a mean of 47%.[129] One peer-reviewed study showed a reduction in numbers of cats with TNR by 66% over an 11 year period.[130]

However, a study by Castillo (2003)[131] found that TNR was ineffective due to feeding locations attracting even more feral cats while also providing a convenient place to illegally dump unwanted cats, although advocates argue that dumping is a separate issue and does not invalidate TNR.[132] A review article by Longcore et al. (2009) argues that TNR advocates are too concerned about cat welfare and not about the effect on indigenous wildlife.[133] The authors argue that populations are not stable and movement of cats is significant between urban areas and nearby woodland. They also state that cats can reach high densities when there is a reliable food source without proper sterilization and management. California State University researchers published mathematical models of feral cats populations suggesting that 71–94% of a population needs to be sterilized for the population to decline, based on case studies of San Diego and Alachua Counties.[134]

Effect on wildlife[edit]

Main article: Feral cat

The trap-neuter-return approach is controversial. Many 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.

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.[133]

In the U.K., 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."[29] This evidence is despite the common practice in the U.K. of allowing cats access to the outdoors,[135] which is recommended to prevent feline obesity (p. 138), and behavior problems and other health problems arising from confinement stress (p. 121).[136]

U.K. biologist and cat behaviour expert Roger Tabor states that "studies from all around the world have found that cats catch relatively few birds compared to small mammals" (p. 135).[136] 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" (p. 135).[136] 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" (p. 123).[137]
