Sleeping Rabbit
Rabbits mostly sleep during the day. They often sleep with their eyes open so its hard to tell when they are sleeping. However a giveaway is that when they are sleeping rabbits often twitch, and their noses stop wiggling. Other rabbits will close their eyes and totally flake out, looking like they are dead. This can result in quite a fright!
