That looks super, I am planning on making one for my bunny also. I just got done making one for our girl piggies, and a seperate one for our boy piggy. I like your idea of just setting it on the floor and having a type of a gate, that is nice. Great Job!
No, the hay rack was just a metal holder for a desk I found in the dollar store but I have changed it. I found a large metal holder in the thrift store, it looks like it was part of a dishwasher or so!!!
