Gypsy, to put it bluntly, is an overweight long-haired cat (she's been on a diet since I adopted her). She sometimes has problems cleaning herself properly after using the litterbox. I give her a good brushing nightly, but tonight for the first time I noticed some matting around her urethra. I'm going to keep an eye on it, to make sure it's not discharge, but would appreciate any advice on de-matting this area. Tonight, I softened the area with a wet washcloth and worked the mat out with my fingers. Is this the correct way?
