I have a question about cat health....?

Could be normal....is he up and playing at night? Cats do sleep a lot.....and if yours are like mine, they seem half-dead, till you try to go to bed...then they want to jump on the blankets and attack the bed mice! (ie - your feet!)

You've never had a cat over a year? You should let a vet check him out. Even though he seems healthy, he could have some sort of issue that needs addressed. Kittens do sleep alot but anytime a cat starts acting out of the ordinary avet check is in order.

cats sleep about 16 hours a day,just like lions!cats are designed by nature to expend energy in short,intense bursts(catching prey if ur a wild or feral cat,or playing,if ur a pet)and then saving their energy for the next burst.lions and other wildcats spend 16 to 18 hours sleeping!cat sleep is light sleep,however,theyre up in a flash if they hear a noise.this behaviour is so normal in cats,it gives rise to the phrase"taking a catnap."some people get a second cat to keep their first company,as they fear the cat will be lonely while theyre out at work.unlike dogs,ur cat will not be lonely-he will doze the day away!
