Spaying and neutering homeless animals

Stray animals can be spayed or neutered and cared for. PAHS offers three programs of information and assistance for people interested specifically in working with homeless cats, rabbits, or rodents. These membership groups offer advice and spay/neuter assistance when funding is available. Contact PAHS to inquire.


Helping homeless cats in many ways

The Palo Alto Humane Society believes that the most effective and humane way to respond to homeless cats in our communities is by spaying and feeding, not by impoundment and killing. Homeless cats can be cared and provided for, just like housecats. They can be spayed or neutered, vaccinated, and cared for when sick. The Palo Alto Humane Society’s CatWorks will show you how. CatWorks is a spay/neuter program for people who care for homeless cats, or who would like to learn how to take care of them.

CatWorks offers its members

  • • Subsidized spay/neuter vouchers when available
  • • Tips on the care of homeless cats
  • • Occasional meetings to discuss matters of common concern
  • • The backing and reputation of the Palo Alto Humane Society

Whether you have cats living in your backyard, near your office, or in your neighborhood, CatWorks will give you advice on how to proceed.


Spay/neuter assistance for rabbits when funding is available.


Spay/neuter assistance for pet rodents when funding is available.

Ann Nussbaum manages our spay and neuter voucher programs. Please email her with any questions about the programs and to order new vouchers.
