Callisto has a poo problem

she always has poo hanging out her bum. Her poo is really hard to anything i can give her to soften it? I wont let her out of the kitchen-she's currently at the door meowing-till we get the bum thing uh..cleared up. the litter box is in there with her.
any suggestions?

Sadly, no one here is a vet, and no one here can examine your cat. Your best bet, IMO, is to contact your vet and get a check up and go from there.

People here can tell you their experiences with kitty constipation, etc, but I think first you have to find out why your kitty is having issues - and you need a doctor for that. Good luck, and please call your vet today.

Sounds like your cat needs to see a vet to rule out any medical issues first. Then, ask your vet about a change in her diet? What are you feeding her? How long has this been going on? Do you feed her all wet, all dry, or a mixture of both?
