Trap, Neuter, Vaccinate, Return (TNVR)

Trap, Neuter, Vaccinate, Return (TNVR), formerly known as Trap, Neuter, Release (TNR), is the most humane and effective way to reduce the free-roaming, un-owned cat population.

In 2013, The Humane Society of Pinellas played an integral part in passing the Pinellas County ordinance that made TNVR legal in our community. TNVR aids in reducing the stray cat population by spaying and neutering community cats, as well as reduces the spread of disease through appropriate vaccinations. 

What is tnvr?

TNVR is a process in which cats are humanely captured in traps in order to have them altered. The majority of these cats are not social with humans, so they are lured into traps with food. Once inside the trap, the cat's weight triggers the trap door to close and the cat is safely enclosed inside. The cat is then transported to The Humane Society of Pinellas or other participating organizations for spay/neuter surgery. The cat is also vaccinated and its ear is tipped so community members know the animal is altered. Once recovered, the cat is returned to its colony to live out the remainder of its natural life.

benefits of tnvr

Humanely reducing the free-roaming cat population is only one of the many benefits of TNVR. Since all cats in the program are vaccinated against viruses such as rabies and distemper, the risk of other animals and humans contracting these diseases is reduced. Altered cats are less likely to exhibit nuisance behaviors, such as howling, fighting, roaming and urine marking. Furthermore, TNVR supports HSP's mission of reducing shelter euthanasia, as these cats are no longer able to reproduce and overpopulate our community. 

how you can help

The Humane Society of Pinellas works with MEOW Now! in a collaborative effort to provide trapping and surgical services to Pinellas County. We encourage all caregivers to register their colony with MEOW Now! so it can be monitored and we can provide ongoing support. Traps can be rented from MEOW Now! or at HSP's Adoption Center.

Please note that HSP does not trap community cats. All trapping must be done by the individual or by Meow Now! HSP provides fee-based spay/neuter services to community cats to humanely reduce the free-roaming cat population.
