My kitty came home on Science Diet and I am using Tidy Cats small spaces. I have noticed that when Kiki poops it really smells. So what could the problem be? If I change food, what to change it to? I can't afford high priced foods. Or maybe it's the litter, I have never used the "small spaces" before. I was reading another post that said the special kitty litter was good. Should I try that? I think I might need one that isn't so dusty as every one is sneezing, even the cat.
