Exercising?

I bought Brandy another present--I couldn't resist because it was on a huge discount. And the company called it a Cat Exerciser, and I thought Brandy could use some exercise. Of course she is sneaky. She really likes the toy--umm I mean exerciser--until she sees that Corey and I are watching. Then she stops. So actually she liked it even more then the pictures indicate. She would sit and stare at the toy until Corey and I turned away and then she would go after it like crazy. Then the moment I turned around to get a good picture, she would walk away. She is a very frustrating model. :) But I am still not convinced she is getting a lot of exercise...but you be the judge.
