I was thinking of building Georgie an indoor play pen. My thoughts are to build it like a big wall to ceiling cab with wire mesh door panels.
Shelving here and there "play pen stuff"
I was thinking of lining the walls with carpet he can grip onto.
For the floor a nice cushion disposable bedding 4inch thick or so incase takes a fall or wants to burrow.
Any ideas suggestions or warnings about this please let me know.
