Dixie is my kitty poop eater. She doesn't eat the kitty litter outright but does get what's stuck on the poop. She has been doing this since she was a pup. l have the kitty box in a secluded place but every now and then she manages to get to it. It has never caused her a problem other than kitty litter breath. I use the clumping kind but she never gets enough to cause a blockage.

I do agree though... if she is acting lethargic or not her usual self, then she needs to be seen by the vet.
