My cats Choo Choo & Quincy had had runny stools that were grey in color. This had been going on for about a week or two. Today there was only solid stools in the litter boxes. They''ve been eating the same food for about a year. No fever for either of them. I realize that the runny stools is a concern but what about the grey color?

The discoloration in their stool most likely was from mucous in combination with their normal stool color. It can make the stool appear lighter in color and is caused by inflammation in the colon. It sounds like this was a temporary, minor problem and everything is back on track for your kitties. Happy to hear. I would recommend to take a sample of stool from the litter box to your veterinarian so they can check for any parasites in the stool.
