Kitten and kitten (yes, a baby rabbit is also called a kitten) at play. Watch how the little bunny dominates the kitty in 00:45. It looks obscene but it's not--it's just how a rabbit establishes dominance.
Rabbit and dogs at play. You have to watch it especially at 01:14! That's a very trusting rabbit when it lies down readily like that.
Now these are specially trained rabbits, but notice how the third rabbit has her own way of doing things at 02:11. Kinda reminds me of me!
Ah, this is why I have rabbits for pets! If I only had the patience to actually follow my bunnies with a videocam!
