This item came with a fairly-toxic stink. We put the pieces outside for a day. Far less stink,
but I gotta tell ya...still a bit stinky. We quickly assembled it (easy, all parts accounted for). It is pretty adorable. We left it outside another night. No more fumes.

But my cat? She thinks she is literally beyond pet-houses, or expensive food, or a collar, sooooo she isn't using it to spite me.
