My cat has had chronic diarrhea for about two months, it has not caused any change in behavior or caused weight loss. He as problems with getting blocked but when switched to precription diet C/D-s it worsened and they tried W/D which helped some but didn't clear the problem. He has also been treated with metronidazole with no response. He has been treated for infectious causes with no response. Any ideas on what could help?
It is time to see a specialist or more testing to find the route of the problem. I see many cats with inflammatory bowel dz with symptoms similar to your pets. Good luck, vetcare
