The hay was making such a mess on the fleece, I decided to make a separate room and put the bedding in there and the girls are using that as their bathroom. They are so smart :)
It is Magic mat. It is for cages that have wire flooring. It is used to cover up the wire so it is safe to walk on. It does not help much though so people use it as traction for their ramps. You can get it at www.petsmart.com, www.petco.com and you may be able to get it at www.ferretstore.com .
I wish I could find that mesh cubing. I have the typical white grid cubing and my rabbit has taken to chewing off the plastic coating because he doesn't want to be in his cage. I worry about him eating it. I think you got that at target? Could you let me know?
