Spaying and neutering your pet helps with animal overpopulation, benefits your pet’s physical and emotional health, and is one of the most important things you can do as a responsible pet guardian. Learn more about spay and neuter benefits and myths here.

At Berkeley Humane, we strive to spay and neuter as many dogs and cats as possible. In addition to spaying and neutering all of our shelter animals awaiting adoption, we also founded Spay the Bay, which provides low-cost spay and neuter surgeries to local dog and cat guardians.


For pet dogs and cats between the ages of 4 months to 5 years.
By appointment only. Please expect a wait time.
Includes exam, surgery, post-surgery medication, and microchip (if needed).

As we are a non-profit organization with limited staff, our focus is on providing essential care to those who can’t afford it elsewhere. We’re unable to offer full veterinary services, and there may be a long wait time for appointments. Thank you for your patience as we strive to care for our community’s dogs and cats. If your pet needs immediate or time-sensitive care, please contact your local veterinarian.

Our Spay & Neuter Process

Making the Appointment

After you review our spay and neuter service details, please complete and submit an Appointment Request Form. Appointment requests are reviewed in the order they are received. Due to a high volume of requests, it may take several weeks for our volunteer to contact you via phone or email (please make sure to check your spam). Your appointment is confirmed after we contact you, mutually agree on a date and time, and accept your non-refundable deposit. We will also provide you with additional information and forms to complete before your appointment.

Before Your Appointment

Please do not feed your adult pet after 10pm the night before your surgery appointment. Water is okay. If you are spaying or neutering puppies or kittens, please check with us as they may be able to eat.

During Your Appointment

On the day of your appointment, please arrive on time with each of your cats in its own sturdy carrier, and each of your dogs on a leash. Upon arrival, our team will check you in and review your documents. The check-in process will usually take around 30 minutes.

During surgery, we use a combination of medications and oxygen to keep your pet asleep and to minimize any pain. After the surgery, your pet will be kept warm and comfortable in individual kennels and will be monitored carefully as they recover from anesthesia.

Please arrive at your designated time (usually on the same day) for pick up. You will be provided with detailed discharge instructions in a packet.

After Your Appointment

Please review and follow your discharge instructions thoroughly as you monitor your pet’s recovery. On average, full recovery will take two weeks or longer. If you have any non-urgent concerns following your pet’s surgery, please submit a contact form and we will do our best to respond during our business hours (Tuesday–Friday, 8am–3pm). If you need immediate assistance, please contact your veterinarian or local emergency clinic.
