I used to kitty sit for a big, handsome Maine Coon who would situate one of his plush squeaky toys under his left leg and "jump start" it so he could hear it squeaking. He would also do this to a human when sitting on their lap. I figured it was actually a playful action. He was the only cat I have seen who would kick like that. Bless his handsome soul....he is no longer with us.
