TNR involves humanely trapping feral cats living in cities, towns and rural areas and transporting them to a veterinary clinic where they are spayed or neutered. They may also receive a health check, vaccinations, and can be treated for routine medical conditions. After surgery, the cat recuperates for a day or two and is then returned back to his colony habitat where caring individuals provide food, water and shelter. (Kittens and tame cats are moved into foster homes where they are loved and nurtured until they are well enough to be adopted.) Since the cats are no longer reproducing, the colony will gradually diminish in size. By reducing or eliminating mating, fighting and wandering, TNR makes the colony more stable, impacts the influx of newcomers, and improves the health of the cats.

Locally we have implemented a TNR program with the cat colony at Pizza Hut/KFC in Grayson. We have also worked with private citizens with neighborhood cat colonies and individual citizens who have colonies in their barns. Every cat that is trapped is spayed/neutered, given a rabies vaccine, treated with Revolution for ear mites/fleas, and ear notched so that it is obvious they are altered in the future if ever trapped again.
We began this program in the spring of 2017 and have assisted with releasing approximately 75 cats back into their colonies to live out their lives without unwanted litters.
If you would like to sponsor a feral cat TNR, average cost is about $25 for males and $40 for females. Just add a note to your donation that you would like it to go to the TNR program.
