Cats along with mice, pigs and cheetahs love to spend a lot of quality time snoozing. They can sleep for around 12 hours per day. Rats, gerbils and lions are a little ahead of them as they can sleep for about 13 hours a day. This means they essentially spend 2/3rd of their entire lives in dreamland.
As you can see, there are way more than seven animals in this article. You probably won't be surprised to find out which one is the #1 sleepiest! Link
Ferrets. Serious, professional sleepers. I believe the average is upwards of 20 hours a day.
Human babies are supposed to sleep almost 16 hrs a day...you owe me a few months!
Yeah, apparently my guy never got that memo.
