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.

Additionally, 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 428 animals at our mid-year Big Fix on May 7th. On November 5th and April 15th, Animal Care Services contributed towards helping another 450+ cats and dogs at each clinic. Thanks to these collective efforts, we’ve stopped hundreds of unwanted litters from being born into our homes, streets and city shelters.

Big Fixin' Into 2023

To-date we have sterilized about 24,800 cats and dogs at SNIPSA. 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 $52,000 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.
