Matting can be a serious problem. Moisture can get under the mats, causing the skin to deteriorate and even become infected. At the same time, the mats keep getting tighter and tighter, pulling at the already irritated skin. No wonder poor little Pepino is unhappy! Most silky-haired, Angora type cats will do fine with no brushing. But the woolly-haired, Persian-type cats must be brushed daily to prevent the tangles from happening. And whatever you do, don't bathe him! This may cause more moisture to become trapped, and may irritate any infection that may be developing.
