Spay & Neuter

PAH’s Fixes! Spay & Neuter Program

No question about it! Spay and neuter your pets and neighborhood strays.

Palo Alto Humane believes that the most important thing to do for the welfare of animals is to spay or neuter them, so that every puppy, kitten, or rabbit born may find a loving and responsible home. One spay or neuter surgery provides a lifetime of peace and prevents many lifetimes of suffering. Each year, millions of animals are euthanized at shelters across the country due to accidental breeding by free-roaming, unaltered pets.

Contact us for advice on:

  • Spaying or neutering your pet
  • Spaying or neutering stray or unapproachable cats
  • Spaying or neutering on limited household incomes

Support PAH’s Fixes

Palo Alto Humane’s Spay and Neuter program provides critical funding to underwrite spay/neuter surgeries for homeless animals and animals from low-income households.

In 2023, we covered the cost of 1200 spay and neuters. Since January 2024, we have already funded 495 spays and neuters for both community and housed animals. 

PAH’s Fixes is made possible by donations from generous supporters of Palo Alto Humane. We receive no government funding. Consider a donation today and have the satisfaction of knowing your donation prevented countless animal births, and will help reduce pet overpopulation.
