Oh. Logan. What a scare!
So glad to hear that you found Mimi and she is all okay.

My kitty, Kedi did this several years ago when we moving into our house (from a condo). Somehow he got the cupboard doors in the bathroom cabinet open, and hid behind the waste basket.
He was upset with the move and all, so did not make a peep.

I was starting to freak out, when my hubby found him, so I know that awful sinking feeling that you feel.
