I was given two really nice 24x36 rabbit hutches - the red cedar-looking kind they sell at Tractor Supply. Gently used. Because my friend kept them in a covered area, the wood is in great condition. The metal pull out pans are falling apart, though. They are in bad, bad shape! Where can I get replacement pans? I didn't find any at Tractor Supply. I found some on-line at Bass Supply. Is this my only option?
