TNVR stands for "trap, neuter, vaccinate release" which is the trapping, sterilizing, vaccinating, and releasing of feral, stray, homeless, and abandoned cats to reduce the current overpopulation nationwide.

Cats multiply fast, as females can carry two litters from two different males at the same time and are able to start reproducing at around 4-6 months old. In most cases, these cats have been born outside or have been away from humans for some time and are essentially wild animals. Because they are not trusting of humans they are unable to be socialized and aren't suited for life indoors. Each cat that has gone through the TNR process has their left ear tipped to signify that they have been fixed.


While not ideal, stray and feral cats are a direct result of human negligence and TNR is the most effective, scientifically proven, and humane way to reduce overpopulation as these cats are often cared for in colonies which maintain a steady population that eventually shrinks over time as the cats pass away. Not only does TNR prevent further litters in each colony but also prevents more unfixed cats from coming into the area. Other benefits include preventing the spread of harmful and deadly diseases, such as FIV, FeLV, Panleukopenia (feline distemper), and more.

Oakland TNR Coalition's main purpose as an organization is to support TNR efforts throughout our community through trapping efforts and colony maintenance. If you have questions about TNR in your area or concerns about feral cats in the Oakland area, please contact us.
