I'm actually not sure if they are the same company or not, but it sounded like it would attach to any wire crate (which is what I have). MY crate will fit into the pen but I'm too worried he will hurt himself trying to jump on it. That's why I want to attach it TO the crate instead. Yeah, that's what I'm trying to avoid - the worrying about him all day long and that he got out and got hurt!!! LOL Thanks for your help and the suggestions
