Approximately 70% of a cat's life is spent sleeping. It is not uncommon for cats to sleep for up to 16 hours a day.
Cats are crepuscular animals, meaning they are most active at dawn and dusk. Cats may also sleep for short periods during the day and night, and are known for their ability to sleep in odd positions and locations. Cats can also enter a light sleep state very quickly, allowing them to be alert and responsive to their environment.
