My husband found this 'thing' on the street. Looked to be a snake cage, but we had better ideas.
This is how we found it:

We just put tile on the bottom, and then put bedding over that. Thought about making a tray, but with the lip the way it was, this just worked best.

Circles on screws (Don't know the name?) and then opened them up, so they hook onto the hardware cloth. They have a little bounce, but hold up strong.

Narcissus approves.

Adonis and Percy like it too.

In fact, they all pretty much love it.
Still need to dress it up with some bigger seed cups and some neat toys/rope perches, but they all have tons of room now. (It's basically 3' x 3' x 2' I think?)
