Information About Spay/Neuter Services

Thank you for having your pet spayed/neutered at the San Antonio Humane Society (SAHS). This operation helps decrease the number of unwanted pets in our city as well as improves your pet’s chances for a longer, healthier life. We strongly recommend that you establish a relationship with a full-service veterinary clinic to ensure your pet gets continued care, including vaccine boosters, deworming, heartworm and flea/tick prevention, and all health issues NOT directly related to this surgery.

Spay and neuter services are available to the public by appointment only.

We are currently not receiving requests for spay/neuter surgeries at this time. Although spay/neuter surgeries are still being conducted at the San Antonio Humane Society, we are presently in the process of setting up a new simpler scheduling system for spay/neuter surgeries. Please bear with us during this transition, scheduling for low-cost spay/neuter surgeries will be made available again once the system is effectively in place.

Pets must be at least 8 weeks old and weigh at least 2 lbs. See Pre-Surgery Instructions.

A Rabies Certificate, which must include the animal’s name, description, date, and SIGNATURE of the veterinarian, must be presented at the time of drop off in the morning before surgery.

If you do not have proof of current rabies vaccine, we can administer the rabies vaccine at the time of surgery for an additional cost of $10.

Rabies (and proof of vaccination) is required by Texas state law for any animal 16 weeks of age and older, and can be administered as early as 12 weeks of age. More info about Rabies.

Additional services can be performed at the time of surgery for additional fees. See additional services.

Check in and drop off of your pet begins at 7:30 on the day of your appointment. Payment is due when you drop off your pet. Your pet will be ready to go home starting at 4:30 pm. See Post-Operative Instructions.

Grants Available
The city of San Antonio and other charitable organizations do have grant sponsorships available to help assist with costs of surgery. Check our current available grants to see if you qualify. If a grant requires documentation for proof (eg, driver’s license or utility bill), we will not be able to honor the grant without documentation. Please be sure you bring it with you when you drop your pet off in the morning.

Currently available grants (1):
- Zip Code (eligible zip codes for free spay/neuter for your dog or cat).

Feral Cats
Feral cats must be brought in an approved trap, and are limited to 10 surgeries per day on Mondays, Tuesdays, Thursdays, and Fridays. All feral cats will receive a permanent green tattoo on their abdomen as well as an ear tip, to designate sterilized status. We cannot accept feral cats if they are not in an approved feral cat trap, as they are a danger to themselves and our staff. If you have not attended a feral cat trapping training class, please do not attempt to trap feral cats on your own or bring them in an inappropriate carrier. This only creates added stress to the cat, and we will not be able to perform surgery. See info about local feral cat groups/training classes.

During the month of October (Feral Cat Month), we offer special discounts to trappers as well as additional surgery days. We are offering services every day of the week except for Sunday. Weekdays we can do 10 feral cats and Saturday it's 5. First come first serve.
