Normally, the nose does not require any special care. A healthy cat's nose is always moist, but not runny. The moisture on the cat's nose comes from licking and the tears that continuously drain through the lacrymal canals. Consult a veterinarian immediately if your cat has a dry or runny nose.In some breeds with short faces, nasal secretions may form a crust at the edge of the nostrils. Use a cotton ball soaked with a special antiseptic or cooled boiled water to clean the nose.When it comes to the ears, the predominant rule is to touch them as little as possible. The earflap always has a little waxy, sometimes brownish, deposit at the base. This is normal. This waxy buildup should not be wiped away too often, or the cat will naturally produce more earwax. However, if there is excess buildup, the cat's ears must be cleaned to prevent blockage of the ear canal. Never use a cotton swab to clean the ears. The cat may be injured or the wax may be pushed farther into the ear canal, creating a plug that must be removed under general anesthesia. Alcohol or water should not be used to clean the ears. There are a variety of oil-based ear cleaner products available on the market. Massaging the outside of the ear after squeezing the solution into the ear canal removes the waxy buildup without causing pain.If your cat demonstrates signs of pain or escapes while you are cleaning his ears, consult your veterinarian. Your cat may have an infection or some other disorder.
