A spay may run a little bit more than a neuter but still not terribly expensive. I would definitely suggest an appointment for any service as this is a very very busy veterinary office. My personal choice is Dr. Wendy Probst. She is very knowledgeable and is a pet person who will tell you like it is. They are not all created equal.
The last time I had my pups done it was 80 some dollars but they may give you a multi-fix discount lol only way to know for sure is to call them and ask. I've got a idea get rid of the cats and get a dog lol. All kidding aside Harrisburg Clinic is awesome and very good on there prices so give them a call tell them what you are needing and they will get you in quickly the vet is very good and there staff is awesome. P.S. I was kidding don't get rid of the cats.
