Brush away all loose hairs and knots. Place a rubber bath mat in a sink or tub to give your cat a secure footing. Then wet it with a spray hose. Do not spray water directly into its ears, eyes or nose. Gently massage in shampoo specially made for cats, working from head to tail. Thoroughly rinse again avoiding the ears, eyes and nose. End the bathing ritual by drying your cat with a large towel. You may also use a hair-dryer on a low setting but this may scare it away.
