I do, our cat seems to spend half its life asleep. So I checked it out on the net and found the following, cats sleep up the 16 hours a day!
Cats sleep a lot and it is perfectly normal. In fact an
average house cat will sleep the majority of its life away. It's one of their most favorite activities and they are really good at it. Most cats will
sleep about 16 hours a day, and some even more than that.
For some cats its MORE than 16 hours a day! That's not a cat its a living cushion.
