...That's the sound of this super-intense bunny gaze, a la Blue Steel in Zoolander! Sooo Hot right now. Just look at that 'stache!!
This fuzzlet is Darwin, a boy bun who's up for adoption with the Wisconsin House Rabbit Society in Madison, WI. You can read more about him on his Petfinder page here... he sounds like a sweetie! Good luck, little Darwin :)
