Okay I found a new box that had less tape, removed it, and just closed it by folding the flaps over each other, cut a hole, and she's in it right now. :-)
I'll keep an eye out for baskets, but so far I have not found anything that's the right size.
It's funny how fast they decide they love & accept "this new thing" to hide in...you got the "seal of approval" pretty fast. (boxes are fine too)
