That's what I was going to suggest. But, before you give the treat to them, hold it up and say, "What's two minus one?", after they meow, they get the treat.

The way I taught it was you just sit there holding the treat until they happen to meow for you. Then give it to them immediatly.

My kitty will do it sometimes........
