Cool I like your Bunny Barn the only think I'm wondering about is if your using wood won't it trap parasites or do you have to keep dusting it with 7 dust or something like that. I know what you mean by them getting trapped I had the same problem so I made them all one level that I can do for now but will have to double stack them again soon so I'm trying to think of something new then what I had.... I really like your Barn though. Seems like they would get alot of ventilation too!!!
