Trap-Neuter-Return, or "TNR," is the most humane and effective method known for managing feral and stray cats and reducing their numbers. The cats, who typically live together in a group called a colony, are trapped and brought to a veterinary clinic. They're then spayed or neutered, vaccinated for rabies where appropriate and eartipped. The eartip lets others in the community know this cat has been neutered. After they've recovered from their surgeries, the cats are returned back to their original territory where a caretaker provides regular food and shelter. When foster or permanent homes are available, young kittens and friendly adults are removed and placed for adoption. (Information from Neighborhood Cats).
