Why do cats groom themselves?

• The primary aim is to keep the coat in good order. Cats have a grooming routine that enables them to get almost every part of their body with their tongue, which is equipped with comb-like spines to help in the process.
  
• Grooming also perform two other important functions.
  
• First, unlike mammals, the cat does not sweat from most of its body surface area, and the evaporation of saliva from the coat perform a similar function, helping to keep it cool in warm weather.
  
• Second, where two or more cats share a home, mutual grooming plays an important social bonding role between them, particularly between a female and her young.
