The Humane Society of Sonoma County's low-cost spay and neuter clinic is subsidized by donations and is available for low-income residents of Sonoma County. Click here to make a donation in support of our Spay/Neuter services.

Our low-cost services are reserved for cats and dogs. Priority is given to Pit bulls and Chihuahuas.

Our clinics operate on Tuesdays for dogs, and Wednesdays for cats. To schedule an appointment for your four-legged loved one, contact us at  707-284-FIXX (3499).

Appointments are limited and in high demand. If you are not in need of financial assistance we encourage you to contact a local veterinarian for spay and neuter services or contact the Humane Society of Sonoma County's Public Veterinary Hospital at 707-284-1198. Located at 5345 Hwy 12 West in Santa Rosa, the Humane Society of Sonoma County's veterinary clinic provides a high standard of compassionate care for your pet.

What services are provided for pets at HSSC Spay/Neuter Clinic?

  • Spay or neuter surgery
  • Pre-surgery exam
  • Rabies vaccine
  • FVRCP vaccine for cats/DHPP vaccine for dogs
  • E-collar (when needed)
  • Microchip (when needed)
  • Pain medications

Which animals will be accepted for surgery?

All animals will be examined by a veterinarian to determine if they appear healthy and can undergo surgery. The SHS Spay/Neuter Clinic generally accepts:

  • Healthy dogs and cats between 3 months and five years old.
  • Puppies and kittens at least 8 weeks old and weighing at least two pounds.
  • Female cats in heat (can be evaluated on a case by case basis).
  • Pregnant cats and dogs, depending on the health of the animal and term of pregnancy.

Which animals will NOT be accepted for surgery?

The HSSC Donor-Subsidized Spay/Neuter Clinic cannot accept:

  • Ferrets, rabbits, or any animal who is not a cat or dog.
  • Unhealthy animals or those with contagious illnesses (animals should not be coughing or sneezing, and should not have watery eyes, runny noses, mange, or ringworm).

Certain animals may be accepted on a case-by-case basis, depending on the outcome of the veterinarian examination:

  • Female dogs and cats who are nursing puppies and kittens (it is ideal to wait to spay a canine mother until two months after she weans her litter and a feline mother 2 weeks after she weans her litter).
  • Male animals with only one testicle.
  • Animals over five years of age.

Why do you give priority to specific breeds and species?

  • HSSC has limited funding to provide low-cost services. We reserve our precious resources for animal species and breeds who are most at risk of being surrendered to our local shelters.
  • Cats, Pit Bulls, and Chihuahuas make up the greatest population of homeless and abandoned animals in Sonoma County.

How many pets can I bring for spay/neuter surgery?

  • HSSC encourages Sonoma County residents to spay/neuter all household pets.
  • Residents are welcome to bring all dogs and cats in the household to the HSSC Spay/Neuter Clinic, but due to high demand for services, a policy of two pets maximum per household per clinic day MAY be applied.

How should I prepare my pet(s) for spay/neuter surgery?

  • Keep cats indoors the night before surgery.
  • Animals should have food removed at midnight prior to surgery.
  • Do not withhold water at any time.
  • Bring cats in carriers with one cat per carrier.
  • Bring dogs on leashes.
  • If you do not have a leash or carrier, please leave your pet in the car and request one from our greeter.

What should I bring with me when my pet is admitted to the HSSC Spay/Neuter Clinic?

  • Bring photo identification showing you are 18 years of age or older.
  • If you are transporting a pet for someone who is disabled or elderly, bring that person's photo identification and proof of residency.
  • Bring any vaccine records for the animal.

What can I expect when I arrive at HSSC Spay/Neuter Clinic?

  • We suggest clients arrive at the location at 7:30 A.M. for a cat appointment and at 8:00 A.M. for dog appointments. HSSC serves 15-35 animals per day when filled to capacity.
  • Be prepared to wait approximately one hour for intake of animals.
  • Please be prepared to pick up your pet at approximately 3:00 pm. Pickup times vary, so check with the onsite SHS representative for actual time at check-in.

How should I care for my pet after surgery?

When your dog or cat is discharged from HSSC Spay/Neuter Clinic, we’ll provide you with instructions for post-operative care.
