Do what Tyson does - punch it in the balls.
That's a true story, for those who don't know. Before his bankruptcy, Tyson owned at least one "pet" tiger, which he enjoyed wrestling around with.
Whenever it got a little....rambunctious, he would punch it in the balls.
Frankly, even if I'm an 800 lb. beast with razor sharp teeth and claws, I wouldn't want that guy love-tapping my nutsack.
