I have this folding 8 panel wire crate that you can shape it all sort of ways. I'm using it as a playpen for my 12 week old Yorkie. It works great as I can close it up smaller or expand it to make a sort of wall and contain him in section of a room. I love it and plan on buying another. This one was originally used to close off a space outside for my female Yorkie so she could safely play outside while I tended to garden.
Just thought I'd pass this on as the uses of the folding-expanding crate seem to solve a lot of problems.
