Cats typically sleep between 12 to 16 hours per day, with some cats sleeping up to 20 hours in a 24-hour period. Kittens and senior cats tend to sleep more than adult cats. Cats are crepuscular, meaning they are most active at dawn and dusk, and they take multiple short naps throughout the day rather than sleeping in one long stretch. Their sleep includes periods of deep sleep and lighter catnaps, reflecting their natural instincts and energy needs as predators.
