Is the disease Feline Odontoclastic Resorptive Lesions (aka Neck Lesions)? If so, I have 4 with it; basically, they resorb their own teeth and are MUCH happier when the nasty mess is pulled. Jazz has gained about 6 pounds since his last pull, in the Spring. He now has 1 fang and a couple of teeth, but he says better to have no teeth than ones that hurt!!!
