Spay and Neuter Services

Schedule a Spay/Neuter appointment

Please click on the button below to schedule your pet’s appointment.

A $25 non-refundable deposit is required for Spay/Neuter appointments, payable when you schedule the appointment. Your deposit will be applied to your service fees the day of your appointment. The remainder of your payment is due during check-in on the day of your appointment. If you give us less than 48 hours notice before you cancel/reschedule or no call/no show, you will lose your deposit.

Please note we are currently scheduling spay or neuter surgeries for one month out.

Rabbits are very sensitive to stress and long-distance travel, especially post-surgery. For this reason, we are only performing spay/neuter surgeries for rabbits who live in the following counties: San Francisco County, San Mateo County, Santa Clara County, Alameda County, and Contra Costa County.

To schedule an appointment:


Spaying and neutering is the key to solving many of your animal’s health and behavior problems and is the most effective way to stop the tragedy of pet overpopulation in San Mateo County. Trained staff in our donor-supported clinic — located at the north end of our shelter (12 Airport Blvd.) — perform spay and neuter surgeries on every animal adopted from PHS/SPCA, and provide low-cost surgeries for members of the public and their animals. Appointments are necessary.

Dogs are admitted between 7:00 am and 7:30 am. Cats and Rabbits are admitted between 7:30 am and 8:00 am & discharged between 4 pm and 5:30 pm. After admission, please expect to wait for your pet to be examined. Wait times vary depending on each pet and when you check in. Clinic hours are Monday–Friday from 7 am – 11 am, and 12 noon – 6 pm. To make an appointment, please read through the bullet points and click the button above to schedule an appointment.

You are welcome to pay the minimum PHS/SPCA fee, however, any additional amount you can pay toward the actual cost of the surgery will greatly benefit the shelter animals. We charge additional fees for animals who are pregnant or obese or those who have had a cesarean because they require more time and medical supplies.
