hi there..im concerned about my kitten who's about 3 months old. When we first purchased it at a pet store it seemed fine as in it was going to the the bathroom regularly. suddenly it began going diarreah everywhere. my parents still have not taken it to a vet and its been going diarreah now for about a month. im very discouraged because it isn't normal to have those symptoms. so does anyone have any ideas why it keeps having this problem. we feed it regular Purina cat Chow which is good for kittens and we dont feed it other food or milk, just water. it did have deworming shots before we got it but i dont think shots have an effect on their immune system. ive also looked in its stool and found no traces of worms of any sort. so what is causing this? please give your input
