how much do kittens sleep
ADVERTISEMENT. Cats sleep an average of fifteen hours a day, and some can sleep up to twenty hours in a twenty-four hour period. Which raises the question: Why do cats sleep so much? The first thing you should realize is that cats are most active between dusk and dawn, which means that they sleep mostly during the day and become active around twilight. This can come as quite a shock if you're bringing a new kitty home for the first time.
