Just took our cat to the vet for annual vaccinations and checkup. He has gum disease (gingivitis). Vet said he can recommend special food but there's no guarantee cat will chew it sufficiently for it to work. He recommended a descale and polish under general anaesthetic, which will cost £200-250. It's not covered by our pet insurance.
What concerns me is that we could go ahead with the treatment but there's nothing to stop the cat getting gum disease again. He's only about five years old.
Would it be really terrible and cruel to just leave it be? Has anyone any experience of the treatment?
