neuturing and spaying

Question
How do we go about having our piggies "fixed"?  We rescued a male after we already had bought a female and do not wish to breed (Sorry  but we do not believe that there is a need for anymore unwanted animals in the world right now)  and we don't know whom to contact about this.  We go to an animal hospital for our dogs would they be the ones to contact about our piggies or is there some place we should research it more to find a reputable vet that works with small animals.  

Answer
Thank you so much for not contributing to the over population of cavies.
You want to get your male neutered as it is safer to do. Look in the phone book and call around for different exotic vets. You want a vet that knows about cavies.
