Hi everyone. I think it's time to upgrade Raine's cage!

Her current cage is nice and all, but I think she needs something with more room, being the overly curious and active type. I saw before four bins that had been put together by PVC pipes, allowing the hedgie to have four rooms. If I find the link, I will post it. I thought it was very neat, and I was thinking of doing it with two or three bins. What type/brand of bin is reccomended? And I've always tried to find the right size PVC pipe, but never seemed to find any. [For her to play in] What size do I need? Thanks! -Brandi [Before & After pics to come!]
