Hi! My new cage is coming in the mail tomorrow (Midwest Expandable Guinea Cage, because of the problem stated below). I'm going to use the old cage as the kitchen area but I'm not sure what to do as the ramp. I've literally looked EVERYWHERE (Target, Walmart, Kmart, Five Below, Dollar Store, Home Depot, Office Depot, etc..) for the C&C grids and coroplast. I need to make a homemade ramp but I'm not to sure what to use? Any help appreciated!! Xoxo
