In response to Santa Clara County’s mandate to shelter in place, Humane Society Silicon Valley has temporarily suspended most of our services. These measures are being taken in an effort to keep our staff, volunteers, and customers safe, follow recommendations by local and public health officials, and utilize our staff, volunteers and supplies for the highest life saving impact. Learn more about these changes.

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. Given the high demand for community cat surgeries, please note that the number of community cats we can spay/neuter each day will fluctuate and will be based on each day’s surgery capacity.


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

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. Two traps per trapper max. We can accommodate community cat surgeries Tuesday through Saturday (not Sunday or Monday) on a walk-in basis, no appointment needed.

Please note: the number of community cats we can spay/neuter each day will fluctuate and will be based on our that day’s surgery capacity.

If you are planning on a mass trapping (more than 5-6 cats), please contact us in advance at

Milpitas Community Cat Program

HSSV has launched the Milpitas Community Cat Program (MCCP) – a targeted TNR clinic aimed at helping at least 400 cats from Milpitas. We need your help to make it possible!
