If you've got insomnia or if it might just be time for that afternoon nap, here's the perfect video for you.
Not only are these adorable animals all in the throes of sleepiness, unlike humans, they're not trying to cover it up. Nope, they're letting it all hang out.
Seals and otters definitely show their share of wide open mouths, but did anyone else notice the trend toward sleepy monkeys and big cats? Those guys pack some yawns!
The video is going to make you ready to cuddle up in a big blanket and go to sleep... Which is pretty much the most perfect thing ever.
