Trap Neuter Return

The Spay Neuter Hotline's Trap-Neuter-Return (TNR) program is for free-roaming, primarily feral, cats. Cats are humanely trapped, spayed and neutered, ear-tipped and returned. TNR is the most humane and effective method for stabilizing outdoor cat populations. For information or assistance please call the Hotline at: 602-265-7729 (SPAY) or email:

What is TNR?


Free-roaming, primarily feral, cats are humanely trapped. This process is preformed by those requesting participation in the TNR Program or volunteers assisting those who qualify for “trapping assistance”.  The traps used are humane, “TruCatch box traps.”


The cats are spayed or neutered by a veterinarian. This involves an ovo-hysterectomy for female cats- surgical removal of ovaries and the uterus  and castration- removal of the testicles for male cats.  These surgeries are sometimes called “fixing” your cat.

The left ear is “tipped” to identify the cat as fixed.  This procedure is performed while the cat is under anesthesia at the veterinary clinic.  This is a universal identifier of a sterilized homeless/street/feral cat.


The cats are returned to their original colonies’ location where caregivers may continue to provide food and water

What is a Feral Cat?

Feral cats are domestic cats that have not been socialized to people. When left to themselves, they continue to reproduce kittens that are only socialized to other cats and are afraid of people. In recent years many tame cats have been abandoned and have joined colonies of feral cats.  As a result, ADLA’s TNR program assists “feral cats” and other street cats, even semi-tame cats that were once cared for by a person/family, but who now live in a cat colony.  

What are the benefits of TNR?

- Ends the breeding cycle and stabilizes the population

- More effective and less expensive than extermination

- Eliminates or minimizes annoying behaviors such as spraying, yowling, and fighting.

- Helps end the suffering of unwanted, homeless cats.

-Reduces euthanasia due to the number of kittens flooding the already overburdened shelters.

Help Free-Roaming Cats Through TNR

Thanks to Fox 10 News for sharing this story about the ADLA and AHS TNR Program.  ADLA is happy to report that it has TNR’d 5,000 cats in the first year of the TNR initiative with Arizona Humane Society. 3,500 of those cats came from six target zip codes that have highest surrender rates at the Sunnyslope shelter. The rest came from low income caregivers throughout the Valley who came to the monthly clinics at AHS. Thank you AHS!  



What do I do about the kittens?

There are many variables to consider when you find kittens in your yard.  If they are with their Mom, let them stay.  Even if you don't see her, she may be nearby. The kittens best chance for survival is with their Mom.  Trap Neuter Return (TNR) may be your best option for Mom and kittens.
