how much money would I spend to get my cat nudered?

And I have been going to the Revere Pet Clinic for 11 years now and still am happy with the service and price. If your animal needs immediate help, emergency, you should go to the angel memorial or the one in Woburn

Probably a few hundred dollars. I'd say around $200. But Revere pet clinic as well as the ASPCA have voucher (Friends of animals program or also SNAP)programs available for discounted rates if you qualify.
