After celebrating his second birthday, my cat Gatsby was diagnosed with Stomatitis. His whole mouth was swollen with a few ulcerations on the roof of his mouth/on his gum line. He constantly had blood on the side of his mouth, stopped eating all of his food,  became depressed, irritabile, and stopped playing with his feline brother.
 
Unfortunately, there is no  consistently successful long-term medical management options available. Gatsby's only option to live a pain free life is full mouth extraction. If that sounds pretty aggressive, I'm afraid it is. But this disease process is also very aggressive, and when you have full, degenerative disease occurring in the mouth, without aggressive intervention, many cats will stop eating and begin the dying process.

With full mouth extraction, he will experience dramatic relief and his quality of life will improve significantly.

Please help Gatsby live the rest of his many years to come pain free!
