Like dogs, your cat should only be fed as much food as it needs to maintain its optimal body weight and condition. Ribs should not be visible and there should be no excessive fat.
Excessive fat is usually most noticeable between the back legs in the abdominal region.
They will usually eat every few hours all day long if left to themselves. If obesity is a problem, or only canned food is fed, scheduled-feeding, that is, feeding a specific amount of food at specified regular mealtimes, is recommended. Fresh water should be available at all times. Tablescraps and between meal snacks should be avoided. Well-intentioned owners often add vitamin, mineral, or protein supplement to their pet's diet under the mistaken impression that this will be beneficial to their pet.
