Occasionally, cats need to be bathed. Before bathing, comb and brush out all mats. Put a drop of mineral oil in the eyes to protect them from the soap suds. Some people use cotton balls in the ears.
To bathe, when your cat is thoroughly wet, apply the shampoo on his back and work it gently through the coat for about 10 minutes. Be careful not to get soap in his face or mouth. Use a washcloth or sponge to clean and rinse his face and paws. After thoroughly rinsing all soap, keep your cat indoors and away from any drafts.
