I have a question, I'm not sure if I spelled Diarreah right or not, i think probably not, but anyway...Merlin was inside for awhile today, and when he used the litter pan, his bowel movement (for lack of a better word) was a pale yellowish green color, and there was a bit of blood in it. I'm not trying to be disgusting, but I wondered if anyone knows why this would happen....he seems healthy, and hasn't eaten anything different than normal. It was a very loose stool also. Should I be worried?
