​Our Purpose

The Big Fix is an all volunteer 501c3 non-profit organization that was founded in May of 2005. Our mission is to humanely reduce the number of feral and homeless cats in Kerr County, Texas. We do this by trapping, sterilizing and vaccinating each cat against rabies.  We use local vets in Kerr County to spay and neuter.  Once that is complete cats are returned back to their colony where they will continue to be fed and cared for. This strategy is called T-N-R or trap-neuter-return. This strategy is endorsed by a number of well-respected animal organizations such as The Humane Society of the United States and Alley Cat Allies.

We also assist with the cost of getting domesticated cats fixed and vaccinated for rabies.

We only service cats in Kerr County, Texas.



Our only purpose is to sterilize & vaccinate feral cats. We do not relocate cats or treat sick or wounded animals.

Why do we tip the ears?

​When cats are ear tipped, animal control officers, shelter workers, and caregivers can easily and reliably identify them as being part of a TNR program. This ensures that all cats in a colony are humanely managed and prevents shelter euthanasia of cats who are part of managed colonies. It’s important to tip ears rather than notching them, since notching may occur as the result of fighting—especially in tomcats—and may be mistaken for a sign of previous TNR.

Vaccinate against rabies

Rabies is a core vaccination for all cats—an absolute necessity. Rabies is endemic in the U.S., and vaccination is the most effective method of control. All cats are vaccinated at the time of surgery.

Spaying Pregnant Cats

Although it may be emotionally difficult, spaying pregnant cats is truly a humane course of action. Delivering and raising kittens outdoors is stressful for both mother and kittens. The mortality rate of feral kittens is high--often more than 75 percent die within the first several weeks of life. Additionally, pregnant feral cats often migrate prior to delivery to find a secure nesting site. Even is she chooses to deliver her litter nearby, it can be very difficult to locate and capture the litter once they are born outdoors. Finally, retracing her steps may prove to be difficult if not impossible. Confining pregnant feral cats through delivery of their kittens is extremely stressful and not recommended. 

Neutering Male Cats

Decreased Aggression: Testosterone greatly affects aggression in cats. One of the most important behavioral advantages of castration is that as adults, these neutered cats will tend to be less aggressive towards other cats.

Decreased Spraying: Spraying urine is a normal sexual behavior of uncastrated male tomcats. Some unspayed and spayed females, and some castrated males, will spray, but it is much more common in unneutered males. 

Decreased Roaming: Male cats neutered at an early age will generally not sense or respond to pheromones, and would certainly be less stressed and tend to stay home if they are outdoor cats.
