The female purred loudly as you approached, and the male held up a single paw like hand when you were within ten feet, "Close enough stranger."  He snarled, showing sharp pointed teeth, "What do you want?"<br/>The female's tail swished back and forth and she rubbed her hands along her partner's body, "Be nice, maybe she wants to play."  The way the woman said 'play' made you feel uneasy, it was said almost as a predator, and you weren't sure you'd like their style of play.
