Is your pet eligible to be scheduled for their surgery appointment? Please note: all dogs and cats must be at least 8 weeks old and weigh at least 2 lbs. at the time of surgery.

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.

Check in begins at 7:30 am. If payment was not made online, payment is due at check in. Please note: a 30-minute to 1-hour wait during check-in is possible during our busiest days. A rabies certificate (which must include the dog or cat’s name, descriptions, administer date, and veterinarian signature) must be presented at check in. If proof of current rabies vaccine is not available, our staff will administer the rabies vaccine to your pet at the time of surgery for an additional cost of $10. Additional services can be performed at the time of surgery for additional fees. Please see above for services and pricing.

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

Free Spay/Neuter Zip Code Grant – FUNDS DEPLETED: Not Currently Taking Appointments

Please continue to check back here for updated information.

The city of San Antonio and other charitable organizations do have grant sponsorships available to help assist with cost of surgery. Please review zip code grant availability, before making your appointment. For zip codes that qualify for FREE spay/neuter surgeries, please email prior to scheduling. A unique coupon code will be sent to those eligible pet owners which will exempt them from payment. This code should be used when scheduling the appointment. If a grant requires documentation for proof of zip code (eg, driver’s license or utility bill), please bring it with you when you drop off your pet on surgery day. We will not be able to honor grant sponsorships without proper documentation. Missing documentation will result in payment required for services.

*Feral Cats Spay/Neuter Program

Feral cat spay/neuter surgeries at the SAHS on 4804 Fredericksburg Rd. and at the Brooks Spay/Neuter Clinic on 8034 City Base Landing are limited to 10 surgeries per day at each location.

Check-In Days & Time by Location:
San Antonio Humane Society (4804 Fredericksburg Rd): Monday – Friday at 7:15 am
Brooks Spay/Neuter clinic (8034 City Base Landing): Tuesday – Friday at 7:15 am

Feral cats must be brought in at check-in (7:15 am) in an approved trap. 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 for surgery 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. Learn more info about local feral cat groups/training classes.
