Trap Neuter Return

The Spay Neuter Hotline offers the only viable solution to the exponential reproduction of cats on the streets of Maricopa County.  Spaying 15,000 cats per year and over 100, 000 cats since 2009, Spay Neuter Hotline TNR services bring together an amazing group of volunteers and veterinarians who help neighborhoods  stop the birth of homeless kittens by trapping and sterilizing cats and returning them  to live out their lives in the colonies where they were trapped.

The Spay Neuter Hotline provides Trap-Neuter-Return (TNR) for outdoor cats at a number of veterinary clinics in Maricopa County. Cats are humanely trapped, spayed and neutered, ear-tipped and returned. TNR is the most humane and effective method for stabilizing outdoor cat populations.

What is TNR?


Free-roaming, outdoor 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.
