My bun gets at least 45 minutes a day. Usually closer to 2-3 hours though. It varies depending on if I'm home or at school. And I've heard and read many things about the wire bottoms. Eeyore gets a "blankie" that covers just a little under half his cage. We usually take my old sweatshirts or bath towels and cut them to put in there. He's not a chewer at all so its not a big deal. It makes a nice little bed for him and he LOVES them. If you try to move them, he'll hop right on it and won't get off! He loves his woobies!
