Trap/Neuter/Return (TNR) is a program where volunteers successfully trap feral cats, have them sterilized, ear-tiped, vaccinated and then return the cat to their colony (including newcomers or those that sporadically visit the colony).  If 75% of a colony is successfully sterilized the colony will eventually diminish and should naturally become extinct. 

Spaying/neutering, ear-tipping and vaccinating, is the best thing that can be done for stray and feral cats. They will be healthier and live longer if they are spayed and neutered. The females will not be continuously pregnant and nursing. And, male cats will not fight for mates and roam to seek females with which to mate. The number one priority when discovering an individual cat or a colony is to safely and humanely trap and see that they are vetted.

Also included in the humane approach of co-existing with feral cats is to help manage the colony long-term by providing food, water and shelter. Feeding and providing shelter for feral cats allows them to peacefully co-habitat in an area. Many people welcome them for rodent control, providing nutritious food keeps them both from roaming in search of a food source and also less susceptible to disease and parasites.

Three important factors in TNR:

1) Never use darts or tranquilizers to attempt to catch a cat. These methods are dangerous and stressful to the cats. Nets are also not recommended for the same reasons. Use humane box traps.

2) NEVER attempt to pick up a feral cat, particularly to put her in a carrier or trap. No matter how sweet she seems, handling a cat who has never—or not recently—been touched will frighten and stress her. She may struggle to get away and harm you in the process. With no vaccination records, she is bound to be killed or put into quarantine. Use the correct trapping practices outlined below and ensure the safety of both you and the cat.

3) Keep in mind that your trapping will be most effective if you employ targeted trapping.
