Arianna had been stalking through the forest in her animagus form; a midnight black bobcat with unnatural bright green eyes. Her ears flicked toward the slightest noise as she stalked a small mouse. Quite often she came out here now, honing in her skills on trivial little pursuits; her favorite were rabbits. They gave a fast paced chase, but there were none out tonight. None, at least that she detected.
The breeze was turning, about to carry her scent downwind. She bunched her muscles, ready to pounce, but whipped her head up at the sound of human voices. Neither were familiar, but she was relatively new, thus; it was rather an expected thing at this time. She looked back down; the mouse was long gone. She growled lightly and bounded toward the voices. She saw two people, sitting and talking.
The boy was attractive, and the girl equally so. It seemed that everyone around here was gorgeous. The only flaws were personality flaws. She let out a huff of air, which probabaly sounded like a growl to them.
She was about to duck behind a tree to change; she liked switching between her forms to be more secluded; but then decided it may be nice to see their reactions. She sat and waited, hoping she wasn't interrupting anything big.
