I don't know whether I can use the fence or not as the replacement for grids (grids are expensive in here)
It's usually used for mini garden fence....(Bought it new) But all this time, my girls won't jump out of the fence or biting it (they find no interest in biting it) Still going to have more upgrade for the accesories though.

The playground and hidey, I use fleece as bedding and dog mattress.
For the kitchen area I use newspaper as bedding. Easier to be cleaned everyday.
