HSSV's Trap, Neuter & Return Program

Book an appointment for Trap, Neuter, Return (TNR) at our Medical Center—free for Santa Clara County residents!


As part of Humane Society Silicon Valley's (HSSV) mission to save and enhance lives, we offer a program available to anyone caring for feral cats or kittens. We do this to make costs lower for caregivers and more importantly, to be able to offer TNR for all feral cats, regardless of where they reside. The surgery includes spay or neuter, a FVRCP (distemper) and a rabies vaccine and a mandatory tip/notch of the ear (for identification).

Free for Santa Clara County residents (photo identification is required)
$50 for out of county residents

We offer additional services at the time of surgery, by request, for homeless/feral cats:

Combo test (FeLV/FIV) - $45 If you think you may have a sick cat in your colony, it is recommended to test for FeLV and FIV to prevent these diseases from being spread throughout the colony.

Flea preventive treatment - free for Santa Clara County residents, $5 for out of county
We use Revolution (a Pfizer product) flea control which also treats ear mites, intestinal worms (except tapeworms), and prevents heartworms.

HomeAgain Microchip (includes registration) - free for Santa Clara County residents, $5 plus tax for out of county
The microchip is registered for the life of the cat. If a cat in your colony is found and turned in to a shelter, and the cat has a registered microchip, you will be notified so you can help get the cat back to its colony.

Tapeworm Treatment - free for Santa Clara County residents, $10 for out of county

All cats must be brought in a humane trap and only one cat per trap. An appointment is preferred, however we can normally accommodate TNR surgeries on Monday through Saturday (not Sunday).

Drop off Tuesday - Sat: 7:00 a.m. – 8:00 a.m. Pickup same day 4 p.m. - 6 p.m.

Prices of services subject to change without notice.
