TNVR Programs help by:

- stabilizing feral cat populations


- vaccinating to ensure that cats and humans are protected against disease 


- allowing cat caregivers and public health officials to monitor the health of cats in the community


- controlling rodents in your yard or business


- ceasing the growth of feral colonies  that will eventually decrease in size

About Trap-Neuter-Vaccinate-Return

What is TNVR?

Trap, Neuter, Vaccinate, Return, better known as TNVR, is a humane, comprehensive strategy for improving the lives of community cats and reducing their numbers. TNR is more effective and less costly than repeated attempts at extermination – costs for repeatedly trapping and killing cat colonies are far higher than promoting stable non-breeding colonies in the same location. Vacated areas are soon filled by other cats that start the breeding process over again. With TNVR, community cats  are spayed/neutered, vaccinated against rabies and surgically ear tipped on one ear (the universally recognized sign of a cat who has been TNVR’ed).  


Once TNVR’ed the cats are released where they were trapped to the care of dedicated, responsible caretakers who feed and provide shelter for them. Their health is monitored and newcomers are removed for TNVR or adoption if tame. This method has been proven over the last 30 years to be an effective alternative to euthanasia and a benefit to the community.

Spaying and neutering a community cat will get rid of most nuisance behaviors, such as spraying, and the ‘fighting’ and “yowling” associated with mating. 

How to conduct TNVR
Alley Cat Allies is the recognized authority on community cats, and their website,, provides a wealth of information on all subjects related to community cats and TNVR. In fact, their site has so much information that it may seem a little daunting. Below are links to PCFCC's "Trapping Instructions" and to two  publications on Alley Cat Allies' website that we believe have good, concise, summaries of TNVR.
