Forgotten Cats was founded in 2003, and was established as a non-profit organization in 2004. It stands by the TNR method: "Trap, Neuter, Release." The success of the program has allowed Forgotten Cats to become one of the nation's largest TNR programs. Their goal is to humanely lower the population of homeless cats.  Forgotten Cats was founded and is run by Felicia Cross from Centreville, Delaware.  The goal of Forgotten Cats is to sterilize at least 500 cats per month. 
Forgotten Cats began with a few dedicated volunteers in 2003. Initially the organization trapped, neutered and released about 20 cats per week but has since expanded to among the largest TNR programs in existence today, sterilizing about 20 cats per day. To date, the organization has sterilized over 14,000 feral cats. The organization also provides low-cost sterilization clinics regularly at two locations. Forgotten Cats also provides an extensive fostering and pet adoption service, working with several local PetSmart locations to place previously feral cats in “forever homes". Overall, Forgotten Cats has been able to adopt out over 5,000 cats.
