Feline stomatitis

Many of us who live with FIP exposed cats, know these cats frequently also suffer from stomatitis. I have 4 cats that suffer from it and I have tried antibiotic treatments in two week intervals every few months on all of them. While it does give some relief, they quickly revert back to terribly painful mouths.
One treatment suggstion has been the usage of zyrtec. I am currently pursuing this treatment and have no firm results yet to report, except that pilling a cat with the painful mouth condition is difficult and stressful and I think that somewhat will counter any benefit of treatment. (antibiotics go into their food)

Recently the opportunity presented itself for one of the cats to get all but her top canines removed while undergoing a spay. She'd already lost most of the teeth (by age 3) and the last few were removed with little effort. A month later, I can report that although her gums are still irritated, the irritation is at least 75% reduced. SO in her case, it was an excellent solution.

One vet, has a very invasive procedure that certainly if finances permit and suffering sufficient I think should be discussed, however I think the expense would be high and would require a dental challenge for the average vet and I would personally recommend a veterinary dental specialist.

While none of us want our pets to suffer in any way, this condition is challenging on many levels and there are no easy answers to it.
