If we just look the info you've provided about your cat with PetzLife aside, we know there is decay and red gums. One concern you tell us is surgery.
If your veterinarian is doing: pre-anesthetic bloodwork, continual anesthesia monitoring, gas anesthesia, IV fluids, nerve blocks for extractions, dental xrays and gingival flaps - then your cat is getting the best care she deserves.
