Something is wrong. Start with cat litter pan. Was it changed recently? Is it in a new location? Was she shut in your room? Next thought, have you given kitty a new food? Given kitty something they don't normally have? Anything dairy can give them awful cramps, too. If you can rule out foods, litter type, litter pan location and cleanliness, then you may want to consider talking to a vet if kitty does this again.

Assuming this isn’t a kitten, the other comment is right. Go through that check list, but add on to it any major changes have been made. Has someone who used to come around stopped coming around, did another animal move/pass away. But yes if none of this explains the behavior they may have a medical problem that they’re trying to ask for help with.

Try sleeping with a man. They shit and piss the bed slightly less.

This is why I dont have cats or dogs. No messes, hey!!.....
