I have 5 house bunnies. One of them loves to scoot an old towel around the floor. He'll dig at it until he has it pushed under his belly, then he smooths it back out only to dig it up again and smooth it out again. My Rex likes to play with an empty margarine bowl and a baby's hard plastic teething ring that looks like a set of keys. She'll pick it up and throw it, then chase it and toss it again. I think it's the satifying clink the keys make that she enjoys most. Another bunny like to throw empty toilet paper rolls around and rips up old phone books. They are wonderful characters and so full of fun. I'd like to hear about other bunny toys since , like a toddler, they get bored with their toys quickly.
