Cats will often sleep fifteen to eighteen hours a day. The main reason is that they are crepuscular, meaning they are most active during the twilight hours of dawn and dusk. The rest of the time is for sleeping, for the most part. This explains the sudden bursts of energy when you’re trying to wind down for the evening or sleep in just a little later.

Your cat is a predator just like lions and other big cats. Their style of hunting is to stalk and creep toward their prey (even if it’s a mouse toy) and pounce or give chase without warning. This takes a lot of energy and all that sleep gives them the reserve they need. Also consider that your cat is dozing most of the time. Cats are light sleepers and need to be able to spring into action at a moment’s notice. For more information, visit the website of AnimERge.
