My girl kitty, Shadow, has had really soft, sloopy poop for about a week now. Also, she had a few "accidents" outside the litterbox. (Pee accidents, not poop.) I took her to the vet and they felt her abdomen and said it felt very liquidy in there, but they couldn't find any obvious problems from the stool sample they took. I'm supposed to give her antibiotics for a week and see if that helps. The weirdest thing is that her poop smells very odd, almost antiseptic smelling. What could this be from?
