When we were in NC we got both cats neutered and full run of vaccs, ear mite treatment and worming for like $160. Our Dog spay was a bit more cause they do it by weight she got vaccs, fecal and pain meds/sedative for a little over $200. Oh, and she was in heat - they charge extra for that because of the additional bleeding risks.
I am nervous about neutering price for our puppy. He weighs roughly 45 maybe more and he's not 5 months yet! We are gonna have to do him soon or it's gonna cost a fortune!!!
