Hey guys i am new to this website as well as owning a kitten! I have adopted from a shelter and she has had diarrhea since the night after she came. She tested negative for worms. I am feeding her performatrin ultra kitten food and was feeding her performatrin ultra cat food mixed with pumpkin but then was told to stop by my vet. The diarrhea has got to a soft serve sort of texture but it still sometimes liquidy. She also has gas. I am adding fortiflora into her food as i got some from a volunteer at the shelter for her diarrhea. I am really worried about this and why it has not gone away yet. Should i switch to hills science diet for kittens? The vet said the quality of the food may not be as good in performatrin. I was told by a lady at the pet valu (she was at foster home then pet valu) that she had diarrhea while at the pet store. I was thinking they did not trainsition her properly from the foster’s food to the food she was eating at pet valu. Sorry for the long post but any advice would be helpful!
