Low-Cost Spay/Neuter Clinic

The Contra Costa Animal Services (CCAS) Spay/Neuter Clinic is currently closed. However, CCAS has resumed Spay/Neuter services for shelter animals that have been adopted and those that have been reclaimed by their owners. Additionally, CCAS has opened our TNR on a limited, by appointment, basis for feral cats to begin piloting public services while practicing social distancing. 

If you are unable to wait for an appointment at our Spay/Neuter Clinic, we suggest contacting our community partners, ARF and Fix Our Ferals, who may be able to assist you with low-cost spay and neuter services for animals in Contra Costa County.

Free Physical Exam

Pets receive a free physical examination when brought in for spaying or neutering. 

Why should I spay or neuter my animal?

Spaying and neutering:

  • Prevents needless reproduction and destruction of animals
  • Is the most effective means of preventing pregnancy
  • Eliminates or reduces the attraction of male animals to the female
  • Reduces the male’s tendency to fight and the resulting wounds and infection
  • Reduces the possibility of cancer or infection of the reproductive tract
  • Results in a generally healthier, more desirable pet
  • Allows spayed and neutered dogs and cats to be licensed at a much lower cost than non-spayed or non-neutered animals
