Cats typically sleep between 12 to 16 hours a day. Kittens and senior cats may sleep even more, often up to 20 hours per day. Cats tend to take multiple short naps rather than one long sleep, which allows them to stay alert to their environment. Their crepuscular nature means they are most active at dawn and dusk, often sleeping during the day and night. This extensive sleep helps them conserve energy for activities like hunting and playing, even if they are domesticated and do not need to hunt for food anymore.
