It’s amusing, or disgusting, or maybe both: a cat or dog scooting her rear end across the carpet, pulling herself forward with her front
legs. Simply put, the animal’s anus itches terribly, and she doesn’t have fingers to scratch it. The itching is caused by worms, so your cat requires medicine, administered either by you or your vet. (But by all means, get your camcorder out while the cat is still dragging, for it makes a great video.)
