Bunny's are sweat animals to have as pets. I bought one several months ago. He was a tiny thing at the time. Now he's a huge thing... His name is Bunnicula, named for the vampire bunny in the children's story, "Bunnicula." I love him to pieces, but he constantly gets into mischief... So to entertain him I leave soda boxes out around the living room. He chews on them and sticks his head inside.
One several occasions I put carrots into the boxes so that he can treasure hunt for treats and entertain himself. On of these particular days, I had put a carrot into a tight soda box. He stuck his head into to get the carrot, but when trying to pull his head out he got stuck.
He ate the carrot first then picked himself up with the soda box still on his head and walked around the living room trying to get the box off. He walked from the t.v. to my deck door. With the weight of the box making him tilt one way and then another. It was so funny and cute, I had my friend with me film it. It's on Youtube and it's very funny. FYI: Bunnicula wasn't hurt in the making of the movie. As soon as the filming stopped, I placed my hand onto of the soda box and to stop Bunnicula from moving. He was able then to pull his head out. He looked at us for a second, shook his head, and hopped off to another soda box. Where he fit his entire body into it to eat a carrot. Didn't film that part, but it was very funny.
