I'm thinking of getting some of these. How many or the wire panels would you need to create a decent sized run?
Either very high, or with a lid (I have a VERY high jumper :lol
You can make them higher with wooden dowels for support. You can make the shelves out of wood too, to conserve the cubes and make them higher.
I've seen a setup 6 high with lots of support, so you can do anything with them really Since they're 14 inches long it would be easy to make a roomy cage too.
