Return to field

A shelter practice of neutering, vaccinating and ear-tipping a healthy free-roaming cat, then returning it to where it was found.

Also called: RTF, shelter-neuter-return, SNR, return to habitat

Return to field, or RTF, is a policy used by some animal shelters. When a healthy, free-roaming adult cat is brought in by a member of the public, the shelter neuters it, vaccinates it, ear-tips it and then releases it where it was found. The cat is not held for adoption, because many such cats are unsocialised and do poorly in a kennel. A related name is shelter-neuter-return.

Supporters say it keeps cats with their territory, saves money and kennel space, and avoids euthanasia of cats that were not at risk of harm outdoors. It extends the ideas of trap-neuter-return to cats a shelter receives. Critics worry about cats that might be friendly or owned, injured cats, and the dangers of outdoor life, so programmes normally scan for a microchip, check for friendliness and illness, and try to find the owner first.

Programme rules differ by place, and some local laws limit releasing animals. A stray with a collar, a microchip or tame behaviour should go through normal stray holding and return to owner steps. If you have found a cat, ask the shelter what its policy is before handing it in, so you know what will happen.
