Michelle Kempner made these cat toys with images of things her cats like. She has a tutorial up on the fffffatlab website and writes:
My cats, Io and Milo, have the standard cat toys. You know like mice and uh… mice. They get enough mice at home since we live above a bakery. I decided to quickly whip up some cat toys of things they like to play with. I started with yarn (Io loves to destroy it) and Milo (Io loves to attack him).
