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.

Making an Appointment

Our Community Cat Spay/Neuter clinic is temporarily closed. Please check back for updates.

We can accommodate community cat surgeries by appointment only. All cats must be brought in a humane trap and only one cat per trap.


  • 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.
