I've mentioned Buffy loves golf balls. She bats them all over the
living room. They've got some heft to them. Every once in a while I
give her a bright orange, same sized whiffle ball. When she bats at it
it goes very fast, sometimes flying! Gives her a nice workout chasing
it around the room. Of course it gives me a nice workout, too, because
I have to figure out where it went and put the ball back in play.

We had a nice session with the toy mousie on the fishing rod, too.
