This game is adorable! I had a book when I was a child that this reminds me of. It was all about finding a cat in each picture. A lot like Where's Waldo? but the art was really charming. This blog post has a bunch of illustrations from the book: http://www.collectiblechildrensbooks.com/2011/01/find-cat.html
