I've had my kitty for about 2 months now (she'll be a year old in may) and ever since I've had her, she's had diarrhea. When I first got her, I figured it was because of diet change (I switched her from Iams to Blue Buffalo Longevity) and I let it go on for a while, thinking it would clear up. When it didn't, I went to PetSmart to get some diarrhea medicine for her and I gave it to her exactly how the package recommended until the bottle was gone, and still nothing. Finally, I decided to take her to the vet (Banfield) and get her checked out. There, they gave her a de-wormer shot, some amoxicillin to give her orally twice a day, and another anti-diarrhea medicine to give orally once a day. I followed this very strictly, never missing a day, and she STILL has diarrhea. I have her on some wet food now to make sure she is getting as much moisture in her diet as she can (which I also took away from her for about a week to see if maybe that was the problem, still nothing). She is also drinking water and eating as she normally should be.
The strange thing is though, she is acting perfectly fine. There are no other symptoms but the diarrhea. No vomiting, no mucus in her diarrhea, no blood, nothing. Her energy levels are through the roof, you would never guess that she has a diarrhea problem. So what I'd like to know is: Is there anything I can supplement her diet with to maybe make her have harder stools? What else is there to do? Should I take her to another vet to see if they recommend anything that the first vet didn't? I'm just concerned because I know how detrimental it can be to a cat if they become dehydrated.
