When I was in elementary school (from 2013-2018), I read a picture book I saw on the classroom shelves. It was a short picture book where a black cat would walk through an abandoned castle/manor of some sort. The only specific detail I remember was a children’s room with old toys in it. I specifically remember a jack-in-the-box and a small toy car, and there may have been some alphabet blocks as well.
What picture book is this?
