Cube Rabbit Cage. This is large enough for our rabbit and two guinea pigs to share. Also, love the idea of using a remnant piece of lino for the easy clean floor. Seal it with some calking and we should be good to go.
Another awesome rabbit cage. Storage cubes, zip ties, PVC pipes to stabilize the shelves. 1"x3" boards to help stabilize the height of the cage. The shelves are plywood that have been varnished to death (so no accidents get absorbed), covered in towels secured with binder clips.
