I have kitten diarrhea problem that is perplexing. I am not familiar with IBS never had a cat with this problem. 3 veterinarian trips and nothing has changed. First treatment Albon with Ben Back, second treatment Metronidazole, food changes from Wet to Dry, then changes to rare only with Endosorb twice daily, then back dry with prednisone. Large number combination recommendation treatment. Today I have no solution other using Ben Back or similar. The Endosorb work for a short time, 3 or 4 days then it explored again. The prednisone treatment was the best increasing the firmness. Something is not right with kitten and I can't seem to fine a veterinarian in my area with something to help. Its liquid. I am asking for help for solutions. His weight seem to stay with .15 pounds, up and down. If I feed him Clinicare or add kitten milk replacement to his food it seem to cause the diarrhea to be watery, I am very concerned at this point he is getting enough nutrition. I use nutroCal with him. Any advise is welcome. He has been tested for various bacteria including the dna test, no bacteria or worms of any kind found to date. I am wondering if there might be major organ that's the problem.
