Make Your Cat Some Felted Toys
This would be an awesome project to do with kids on a summer afternoon. 7 Yaks Design has a step-by-step process that involves getting a bell inside of a whiffle ball, covering it with fiber, and then using pantyhose and your washing machine to create the felting. I'm thinking you could also tuck a little mesh baggie of catnip inside there.
