My 4yr old castrated male cat has, for the past 2 years been visiting the vet with various aliments, mainly concerning his mouth. The first diagnosis was periental desease which was treated. He had been on and off antibiotics for the 2 yrs. His main symptom is a painful mouth which stops him from eating well. He offten has a mucuse like dribble, on occasion when really bad has blood (from his gums) in. During the dribbly times his mouth often swells. He also has bad breath. Antibiotics or a cortizone shot clears this up, but the longest time he has gone with out meds is 21 days. He also takes fluis as there are times when he does not drink. Last winter he had liver and kidney trouble (thought to be caused because he was unable to eat properly). They have cleared up but his weight still fluctulates a lot - I give him a calorie paste with his food. His body temperature his constant but below that of a regular cat. At new year he had he regular blood works done and an ultrsound to check his internal organs with nothing amiss. Although his fur has not grown back yet. Our vet had being great and about the only test he has not had is a pregnancy test!!!! She has come to the conclusion that he suffers from various allergies showing specific sensitivity in his mouth. He is generally ok and does not suffer. I was just wondering if anyone out there had experienced anything similar??
