On the packaging of most provisions, there is a guideline, which is often tailored to the average weight and energy consumption of the animal. By weighing the cat and the amount of food regularly, the owner can check whether enough and not too much is being fed. The nutritional condition of a cat is assessed at the ribs. If the ribs can be felt with a flat hand, then the animal is not too fat. If the vertebral column or pelvic bones protrude very much, the condition is also weak. If the cat is too thick, the ribs cannot be felt, and sometimes a clear apron of fat can be felt in the groin.
