The Maine Coon cat is one of the largest domestic breeds. They are known for their thick coat and raccoon type tail. A full grown Maine Coon cat can weight between 15 and 20 pounds. Another very large domestic cat is the Savannah, a cross between a domestic cat  and a small wild cat.  A breeding program for the Savannah cat is still in its’ infancy as male Savannahs’ tend to be sterile to the four and fifth generation. This is a sleek elegant cat with an exotic look.  The Rag Doll cat is also large and muscular. Males can weight 20 pounds or more!  This cat is quiet and very friendly and is often called the “dog of cats.”  If you are lucky enough to own any of these cats, you will know how gentle they can be. You will also know that you may have to buy extra large cat accessories such as cat beds!
