Question: how many hours should a 3 month old kitten sleep?
Answer: How many hours a day does a kitten sleep? A new born kitten's daily routine is made up of sleeping 90 percent of the time — that is almost 22 hours! As kittens mature beyond the new born stage, they will sleep less; but even at six months of age they still manage to spend about 16 to 20 hours a day dozing.
