My 12 year old cat has gingivitis. He just had a dental cleaning about a month ago because he was gagging when he ate and running off. Took him in and the vet told me it was due to gingivitis. Had the teeth cleaned and it still hasn't got better. It's not stomatitis. I have a cat with full blown stomatitis and this is just plain old gingivitis. He's on 5 mg of pdnisine twice a day. But it's really not helping. I've contacted the vet and they told me it takes time for it to kick in. It's been almost 2 weeks. I'm a getting frustrated. I don't want him to be scared to eat or keep him on prednisone if its not working. Does anyone have any suggestions? My vet claims he's got the gingivitis due to his age and his immune system not being as strong as it us to be. He's never had any health issues before. I hate to see him in pain.
