How'd They Do That?

I can't get my cat to look at me when I call her name. Yet somehow, people can train tigers to sit up on their haunches atop spinning mirrorballs. Maybe house cats and big cats aren't all that closely related. Anyhow, I saw this tiger at Big Cat Habitat here in Sarasota recently. They rescue big cats and other large furry critters, and let them live out there days in peace. But some of the animals get to perform for the tourists, and they seem to enjoy it.
