Mat Control

  One common reason to give a cat a haircut is to prevent and remove mats. Medium to longhair cats develop mats in areas where the hair rubs together, such as in their armpits and groin. Trying to comb mats out is tedious and often painful for the cat. Leaving the matted fur alone is worse, as it continues to pull on the underlying skin and causes irritation.
  
  

Skin Conditions

  Another reason to cut a cat's hair is a skin condition. Parasites, allergies and infections all cause hair loss in cats. Shaving the coat also makes treating the conditions easier, especially if the cat is infested with fleas.
  
  

Ease of Care for the Owner

  Many people get a longhair cat, only to realize that caring for the coat takes more time than expected. When this happens, some people surrender the cat to a shelter. What many don't consider is getting the cat's hair cut. Often, just taking off some of the length makes the coat more manageable for both the cat and the owner.
  
  

Style for Cats

  There are some haircuts for cats that are intended to help with their care as well as look stylish. One such cut is the lion cut. This cut leaves the face and neck hair (or the "mane") alone, shaves the body, legs and most of the tail, but leaves a tuft of hair on the end of the tail. Another style is to shorten the length of the hair around the face and on the neck, shave the entire body but leave the fur long on the the tail. Some groomers adjust the clippers for a cut that basically turns a longhair cat into a shorthair cat.
