This is Charlie's old cage before we found out Charlie was actually a boy, and impregnated his cage mate, Lucy. It was a fully closed cage, but I had the front door open in this picture. The black grids swung open.
I had like 3 layers of fleece on there, it still an anti pill but it seems to be a bit fuzzier. I got it from the remanants (extra left over stuff that is under a full yard) part of Jo Ann Fabrics. At the bottom of the ramp Charlie loved sleeping on that extra layer of fleece.
