Well it arrived missing a whole panel, I reached out and they are shipping it from the manufacturer.  The bottom is a thin wire grate, so make sure to ouy a crate pad or blanket in there. The wire they use to make the panels (that did arrive) is very thin and now I am concerned by dog is going to chew his way out of this thing in a matter of minutes. This is an expensive piece of pet furniture for the flimsy craftsmanship.
