Happy kitten falls asleep while playing with toy

(CBS) - It's Monday afternoon, and I don't know about you, but I could use a little nap. Sadly, that's not a possibility for me, so instead I present to you a kitten playing so hard it falls asleep.

The YouTube video was posted by user sweetfurx4 who writes:

September is Happy Cat's month (according to American Vet Med Assoc.) . This clip shows a happy moment of kitten Moo Moo. She was playing with her favorite kind of toy, something stretchy & light that she can hold on to & gives her a sense of triumph "winning" the tugging game. She had a good time playing with the stretchy ribbon for about 10 minutes & fell asleep belly up , very adorable.

Now I don't know about you, but I personally had no idea September was Happy Cat's month.  So it turns out this caught-on-tape moment is not only adorable, but educational, too.  Okay, maybe that's a bit of a stretch, but there's still no denying how cute this video is!
