Recently adopted an adult cat from a family moving to Guam. She's a sweet affectionate black and white tuxedo cat with a bad habit that's driving me nuts. After she uses the litter box, she drags her butt along the rug and leaves a poopy smear. I'm shampooing constantly! Thought it might be her long hair, or her chubbiness (can't reach to clean properly) and I had her hair shaved at the vets. It didn't work, she's still doing it. I don't think it's worms, I think she got into a bad habit. Please, I'll take anyone's suggestions if you think you can help!!!! Thanks, Mimi
