I'm not trying to "rain on your parade" with the Low Cost Spay and Neuter, because I am a definate believer in getting pets "fixed" at the proper time.
However, please check the credentials of the people who are doing these surgeries carefully. Through working in both a regular vet
clinic and an animal ER I have seen some pretty bad mistakes that the doctors have made.
Again, I'm all for having the pets neutered and know that they make better pets because of it. I know that cost can be an issue for a lot of people, but sometimes you get what you pay for.
