I believe that this is what the site specializes in, but I also know that there are owners on this list who have cages of all sorts of materials, wood, chicken wire, tarps and such. I believe if you have found an appropriately sized cage of any material, then good on ya and your cavy friends! Square footage is the important point everyone was trying to make and at some point, the conversation drifted to cross-purposes. You have appropriate square footage? Awesome!
But please don't take it personally that we LOVE the C&Cs, and that we recommend them. They are versatile, large, and well proven for us. Others have had bad experiences with pet store cages in the past, and even some currently! Plus, with so many choices out there, and so many of them bad, then don't blame us for being a little hinky on the idea.
Group hug and lets be friends again! :grouphug:
