Get Involved. Become a Colony Caretaker

If there are "unowned" cats in your neighborhood living strictly outdoors,
we can help stop the population from increasing, reduce nuisance behavior, and help to ensure their health and safety. We accomplish this utilizing our proven Trap-Neuter-Return program. Simply put, live-trapped cats are spayed or neutered, vaccinated for distemper and rabies by licensed veterinarians, and released back to their natural habitat.

Get involved today! Become a Colony Caretaker and click on the link below to register to join our TNR program. Or, if you are already taking care of a feral cat colony and would like to benefit from our TNR program, please click on the Colony Registration Form, print it out, fill it out and mail it back to us.

Our mission is made possible through the generosity of people like you and members of our community. While there is no required fee for our services, donations are essential to continue helping feral cats.

** The current wait time for a spay/neuter appointment is at least 16 weeks. You will be contacted by a Cats Anonymous representative when the next appointment becomes available.
