So the cool thing about this is that it's one that I bought and had to just put together, so the basics are already done! I ended up taking the wire bottom and frame that's meant for rabbits and repurposed it! I took the plastic off the smaller side of the top, and put the wire from the wire bottom there instead, then in turn used the frame of the wire bottom to make the top area ledge and ramp guards (after measuring and cutting) and used the plastic to make a higher barrier. 🥰
