As part of Humane Society Silicon Valley’s (HSSV) mission to save and enhance lives, we offer Trap-Neuter-Return (TNR) services for anyone caring for community cats. The program includes spay or neuter surgery, FVRCP (feline distemper combo) and rabies vaccines, internal/external parasite treatment, an ear tip, and optional microchip or FeLV/ FIV combo testing.



Free for felines trapped in Santa Clara County.
$50 per feline trapped outside of Santa Clara County.


Additional Services


Combo Test (FeLV/FIV) – $45


Flea Preventative Treatment – Free

We use Frontline Gold & Ivermectin flea control products which also treats ear mites, intestinal worms (except tapeworms), and prevents heartworms.

HomeAgain Microchip (includes registration) – free for Santa Clary County residents, $5 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 the cat gets back to its colony.

All cats must be brought in a humane trap and only one cat per trap. We can accommodate community cat surgeries Tuesday through Saturday (not Sunday or Monday) on a walk-in basis, no appointment needed. If you are planning on a mass trapping (more than 5-6 cats), please contact us in advance at

Drop off Tuesday – Sat: 7:00 a.m. –8:00 a.m.

Pickup same day 5:00 p.m. – 6:00 p.m.
