Strange Pooping Behavior! HELP!!

My 4 month old kitten has had loose stool since last night. The problem is, I witnessed him sit on his own stool in his litter box! This got it all over his behind and his tail, and tracked throughout my home! Why would an otherwise clean kitty do this??? HELP!!!!!!!!!!

Your kitty more than likely needs a vet. Loose stools can be anything from parasites to sickness. Him sitting in his stool just shows you he doesn't feel very good and won't play by your rules until you help him out.
