Yup, that is one cute little hedgehog yawning! I saw this over on a new-to-me blog Brighter Sides (such a cute blog!) and had to hunt down its source. Of course, it's already viral, so chances are you've seen it - but is once or twice even enough? I thought not. Enjoy the utter adorableness!
*I did a couple of yawny screen caps for your further enjoyment
p.s. you'll notice (hopefully?) that I made some changes 'round these parts; did a little redecorating/cleaning! more to come - trying to re-inspire myself :)
