TRAP-NEUTER-RETURN (TNR) is a proven strategy for reducing the number of feral cats without having to euthanize them. These are cats who usually haven’t had socialization with humans and are not considered adoptable, though young kittens may still be able to be socialized. They are neutered, vaccinated, and returned to their original colony where a colony caretaker accepts responsibility for them.   Our friends at Bastrop C.A.T.S. Anonymous TNR Society save many feline lives with TNR.   You can learn more about TNR at this site: https://tnrtexas.com
