What is it?

SNIPSA launched its Big Fix clinics in May 2009. With a significant number of animals being euthanized every day in the San Antonio area, we knew there had to be a better way. How could we target the pet-owning population and bring spay/neuter to one’s doorstep? We found that people were generally receptive to doing the “right thing”; we just needed to make it convenient and doable. Providing this service for FREE was also important to remove any barriers that might dissuade a pet owner from having his pet spayed/neutered. The more sterilized pets in our city, the less entering the doors of our shelters. It was simple.


Furthering Our Cause

SNIPSA depends on grants and private donations to host its Big Fix clinics. Amy Shelton McNutt Charitable Trust, City of San Antonio ACS, and the San Antonio Area Foundation have been critical in helping SNIPSA purchase medical equipment and necessary supplies for our MASH style operations. However, their support is not inclusive in keeping our Big Fix clinics running.

We are also indebted to the hundreds of volunteers and countless veterinary staff that spend hour upon hour ensuring each clinic is a success.

We appreciate all the support we have received from our local community. Your donations are driving the change in San Antonio as we march onward as a No-Kill city. We send a huge THANK YOU to our 2022 sponsors, H-E-B and San Antonio ACS, who helped us spay, neuter, microchip and vaccinate over 400 animals at our most recent Big Fix on May 7th.


Big Fixin’ Into 2022

To-date we have sterilized over 19,500 dogs and cats in our Big Fix clinics. What started as spaying and neutering just over 100 animals at our first Big Fix has evolved into sterilizing up to 489 in one long but amazing event.

It costs roughly $15,000 to host a Big Fix. It is well worth the investment when you consider it costs taxpayers upwards of $350 to impound, house, and ultimately euthanize a single animal at our city shelter. SNIPSA has definitely tapped into a well-received yet under-utilized service for animals in our community.

Adopting or fostering kitties helps SAVE LIVES! ✨🐈 Kitten season is well underway, and despite all of the cuteness, it isn’t such a good thing. This boom that happens every spring stresses the limits of our city shelters and leaves many felines homeless. This is why we care so much about our spay and neuter initiative. ✂️ Sterilizing your community/house cats means less litters being born into the “street life.” Visit to learn how you can adopt or foster one of our felines in need.
