The advrage cat spends HALF of there LIVES asleep. so... yeah...
In itself, possibly not but it suggests that there could be an underlying issue - that requires so much sleep.
It varies greatly with the cat's age. Kittens will sleep 17-20 hours a day. As they age, cats will sleep less, to about 12 to 13 hours a day, but they will also spend a lot of time in a state of lowered awareness that is not exactly sleep and not exactly awake, and that substitutes for some sleeping time. As a cat gets very old, often its time asleep will increase again, to as much as 18 hours a day; but that may be cause for concern as it indicates that the cat's metabolism may be failing.
