Needed – Pattern for Kitty-Cat Theme Bookmark

So, I joined a swap wherein you send your swapee
(1) a mystery that includes a cat;
(2) a knitted or crocheted kitty toy, and;
(3) a bookmark.

I’ve got the book and the toy.
I’d like to knit a cat themed bookmark.
I need ideas.

Oh, I know – a contest!
Whatever idea I use, that person will get a bookmark too!
