Hi Dr. Jean, I'm glad you joined us! I have always believed in holistic medicine and have had a great interest in it for a long time now, my vet is a holistic vet and I've always treated Sash that way. Sash is my 15 1/2 year old tabby cat who is the love of my life. He's been having a lot of gas in the past six months or so and my vet suggested to see what foods seem to cause this the most and stay away from them. Well, the problem is I notice this with just about every food I give him, whether it's canned or dry or whatever flavor or brand, he seems to have gas most nights while he lays on my lap. He does have IBS (intermittent episodes of vomitting) and I believe it could be a symptom of this? He currently takes Prozyme, Coenzyme Q10, Azodyl for some early CRF and occasionally Slippery Elm. Is there any other supplements or things you would suggest to help with this problem?
