It looks very cosy and neat! Are you going to put coroplast on the bottom? I think you should make walls for the second level, but since it's a cage in progress I guess you will! I LOVE those cuddle cups that you have! You have FOUR of them? Where did you buy them?
I made them using fleece and flannel and directions from this site. It was pretty easy and cheap too!. I hope my piggies like them. Thanks for your kind words, yes a ramp and siding is on it's way.
