Persian cats are double coated and there are several reasons not to shave them. The undercoat provides insulation and regulates the body temperature. It helps keep the cat cool in the summer and warm in the winter. Shaving a cat in the summer will actually make it hotter, not cooler as many people believe. If your cat goes outside or even sits in an open window, it will be more susceptible to sunburn and possible skin cancer because the skin is more exposed because the guard hairs (outer layer of the coat) have been drastically shortened. In addition, as a cat ages, the guard hairs may not grow back, the coat can end up clumpy and/or balding. Keep your cat well groomed, don't allow mats to form and he will do fine in the heat. My Holly is a Maine Coon with the thickest, longest coat I've ever seen. I have central air conditioning and a screened porch. On a 95 degree day Holly can be found out on the porch, not in the house.
Holly, Misty & their friend, Jake, the dog.
Onyx, Callie May, Maggie & Kobi forever in my heart.
