Hey Everyone I have a female cat named Mimi, I have owned her for a little more then a year now. she is 6 years old. Since the first day we got Mimi she had very wet stool. We tried to switch her food around and seemed to help for a little then got worse. We had her on Purina One Chicken/rice, Purina One Seafood, Royal Canin Sensitive stomach, Science Diet hairball formula and now on Science Diet Z/d. Every time we switch over her food he stool looks great for a few days then back to sludge. She also seems to cry as if she is in pain and then runs to the litter and has explosive diaheria. Lately she has but having diaheria on the carpet. So this seems to be getting worse. When we got her last year we had a stool test and the vet said no worms but a week later she threw up a worm, we used a dewormer and everything seemed to be ok "stool still wet but not bad", Since she has gotten worse we got her tested again and still nothing showing up for her stool. The vet checked her and said she seems like she is in good health. The vet gave us some Tylan powder to try on her food "she also gave us the new Z/d". The first day we switched her she seemed to have gotten worse, pooped 4 times on the rug in 1 day. She refused to eat any food with the Tylan on it till 1 day ago. Now her eyes or all watery and the vet is telling me its not a side effect of the Tylan! Said she must have a cold now. Im going back and forth here! I really need some help. I even bought her a Comfort Zone plugin" thinking maybe she was stressed because me and my wife work all day and she seems to get the diahera in the morning. I want to try a dewormer again but the vet is refusing it to me since she isnt showing any worms. I need some help please!
