TNVR (Trap, Neuter, Vaccinate, Return)

All members in a community (animals & humans) benefit from TNVR otherwise known as TNR.


TNR cats have tipped left ears.

Why TNR feral (unsocialized) cats in your community? 

Trap-Neuter-Return is the humane and effective approach for stray and feral cats." (Alley Cat Allies, 2022).

 "Now in practice for decades in the US after being proven in Europe, scientific studies show that Trap-Neuter-Return improves the lives of feral cats, improves their relationships with the people who live near them, and decreases the size of colonies over time. Trap-Neuter-Return is successfully practiced in hundreds of communities and in every landscape and setting. It is exactly what it sounds like: Cats are humanely trapped and taken to a veterinarian to be neutered and vaccinated. After recovery, the cats are returned to their home—their colony—outdoors. Kittens and cats who are friendly and socialized to people may be adopted into homes. Grounded in science, TNR stops the breeding cycle of cats and therefore improves their lives while preventing reproduction. It is a fact that the removal and killing of outdoor cats that animal control has been pursuing for decades is never ending and futile. Since feral cats are not adoptable, they are killed in pounds and shelters. With a successful program like TrapNeuter-Return to turn to, it’s hard to believe that animal control agencies continue to kill cats, even though that approach has shown zero results.


"Vaccinations are one way Trap-Neuter-Return (TNR) protects community cats." (Alley Cat Allies, 2022).

"Rabies and FVRCP vaccinations are considered a standard and valuable element of TNR—a program that is extremely successful at stabilizing populations of community cats, also referred to as feral or outdoor cats. The program is also called Trap-Neuter-Vaccinate-Return (TNVR). Vaccinating community cats for rabies as part of TNVR offers the best chance of protection from contracting and transmitting rabies.

FVRCP Vaccines
FVRCP stands for “feline viral rhinotracheitis, calicivirus and panleukopenia.” This common vaccine prevents three highly contagious and potentially life-threatening feline viruses from spreading amongst cats.

Rabies prevention efforts are a public health victory.

Thanks to widespread vaccinations, human rabies cases are now an extremely rare occurrence in the United States. According to the Centers for Disease Control and Prevention, there has been no confirmed cat-to-human rabies transmission in over 45 years.

Trap-Neuter-Return helps prevent rabies.

TNR boosts community rabies prevention. In many communities, TNR programs are the largest provider of rabies vaccinations. Even a single dose of a rabies vaccine can provide multiple years of protection. The immunity that develops after a cat receives a rabies vaccination can last up to seven years.

Vaccinating as many cats as possible better protects an entire colony from disease.

Herd immunity demonstrates how important it is to vaccinate as many members of a community cat colony as possible. Vaccinating community cats creates a barrier to rabies. When a large number of the members of a colony are vaccinated, the risk of infection for the cats who aren’t vaccinated substantially decreases. Once a significant proportion of the cats in a colony are immune, the likelihood is small that an infected animal will encounter a susceptible cat. As a result, the entire colony is better protected from disease." (Alley Cat Allies, 2022, ).
