Cooper always had “kitty breath” with very red and inflamed gums. Changing to different foods did not improve the oral health. But then, in May 2014, he became very fussy about his food. Then in October, he stopped eating and became very lethargic so we rushed him to the Emergency Clinic. At that time, the tentative diagnosis was ulcerative stomatitis although there are many reasons for this cause of stomatitis in young kittens; an overactive immune system was possibly the root cause. He was sent home on a course of antibiotics to control the infection. The antibiotics seemed to work short term. Our regular veterinarian prescribed 2 more series of antibiotics and mouth wash which helped his oral health, but only for a short duration. When we stopped the antibiotic, the problem re-appeared. Our vet told us that the antibiotic would ultimately stop working and suggested that in this circumstance, she recommends a full mouth tooth extraction which may or may not fix the problem.
