For Aurora, it's definitely her fleece house, I can't ever get her out of it!
Chi-Chi loves her hammock and always has
Dart- well he hasn't quite figured out that the fleece is not a monster that's ready to attack him!
I cover a few ledges with fleece and they like it. I sew them like a pillow case cover and slip over the ledge. Then i hang a small section of fleece behind it on the cage and call it a sofa! hehe
