How Long Do Cats Sleep?
On average, an adult cat will spend about two thirds of their day asleep. So, the average cat sleeps about 16 hours a day. Though, indoor cats tend to sleep more – about 18 hours a day. In fact, it’s not unusual for a fully grown indoor cat to sleep up to 20 hours out of 24. Outdoor cats tend to sleep less, averaging 13-14 hours a day.
Cats in the wild are more active at night. They’re built to be nocturnal hunters, and will generally do more sleeping during daylight hours. House cats are more likely to be active during they day, as that’s when their people are awake.
