I think this might be flower fairys old cage actually. Daisy is very happy in it and the Trixie silent wooden wheel fits with about a cm to spare. Daisy likes piling her bedding up and it doesn't leak out. The only thing that's been slightly problematic is the holes that she likes to gnaw on. I've plugged them with those wooden carrot things. You can see a red one in the picture.
