Midwest Deluxe Critter Nation Single Unit Small Animal Cage

I bought this for my grandkids' big rabbit. I'm very pleased with it and so is the rabbit. He climbs up and down the ramps to the different levels playing with his toys. It's very sturdy and the double doors in the front make for easy access when cleaning and feeding him. I like that I can raise the ramp on the top level to close it off while cleaning his litter box. It wasn't that difficult to put together with a little help from my 6-year-old grandson. The directions were pretty clear except they didn't mention anything about the little orange plastic pieces that were in the front and back panels, it wouldn't go together with them in there. I think they were to keep the little square holes from being damaged during shipping, duh! The delivery driver left the box in my driveway behind my car. The box was very heavy so I had to open it and carry the pieces into the house separately. I'm 74 years old and if I can put this together, anyone can!
