Kitten has whiteish poop.

My kitten has a white color in her stool. She ate white cheese in the morning might this be a cause of it?

I would think it's probably the cheese. Cats are lactose intolerant, so it's not going to get processed. Keep an eye on it. Could be an indication of liver problems, but don't start worrying about that unless you see it's a persistent problem. If, in the absence of white cheese, poos return to normal, I think all is well.
