*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 & other feral cats info:

San Antonio Humane Society (4804 Fredericksburg Rd): Monday – Friday at 7:15 am
Brooks Spay/Neuter clinic (8034 City Base Landing): Tuesday – Thursday, Saturday 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.
