My nails click against the pavement. He doesn't notice. I pick up speed, darting around trash bags and empty boxes. Finally, I'm close enough. He hears the steady clicking behind him and stops. I duck behind a Dumpster, peer around the corner. He turns and squints into the darkness. After a second he starts forward. I let him get a few steps away, then resume the pursuit. This time when he stops, I wait one extra second before diving for cover. He lets out a muffled oath. He's seen something-a flash of motion, a shadow flickering, something. His right hand slips to his gun, caressing the metal, then pulling back, as if the reassurance is enough. He hesitates, then looks up and down the alley, realizing he is alone and uncertain what to do about it. He mutters something, then continues walking, quicker this time.

As he walks, his eyes flick from side to side, wariness treading the border of alarm. I inhale deeply, picking up only wisps of fear, enough to make my heart pound, but not enough to send my brain spinning out of control. He's safe quarry for a stalking game. He won't run. I can suppress most of my instincts. I can stalk him without killing him. I can suffer the first pangs of hunger without killing him. I can watch him pull his gun without killing him. Yet if he runs, I won't be able to stop myself. That's a temptation I can't fight. If he runs, I will chase. If I chase, either he'll kill me or I'll kill him.

As he turns the corner down a connecting alley, he relaxes. All has been silent behind him. I creep from my hiding place, shifting my weight to the back of my foot pads to muffle the sound of my nails. Soon I am only a few feet behind him. I can smell his aftershave, almost masking the natural scent of a long day's work. I can see his white socks appearing and disappearing between his shoes and pant legs. I can hear his breathing, the slight elevation in tempo betraying the fact that he's walking faster than usual. I ease forward, coming close enough that I could lunge if I want to and knock him to the ground before he even thought to reach for his gun. His head jerks up. He knows I'm there. He knows something is there. I wonder if he will turn. Does he dare to look, to face something he can't see or hear, but can only sense? His hand slides to his gun, but he doesn't turn. He walks faster. Then he swings back to the safety of the street.

I follow him to the end and observe from the darkness. He strides forward, keys in hand, to a parked cruiser, unlocks it, and hops inside. The car roars and squeals from the curb. I watch the receding taillights and sigh. Game over. I won.

That was nice but it wasn't nearly enough to satisfy me. These city back-streets are too confining. My heart is thudding with unspent excitement. My legs are aching with built-up energy. I must run.

A wind gusts from the south, bringing the sharp tang of Lake Ontario with it. I think of heading to the beach, imagine running along the stretch of sand, feeling the icy water slapping against my paws, but it's not safe. If I want to run, I must go to the ravine. It's a long way, but I have little choice unless I plan to skulk around human-smelling alleyways for the rest of the night. I swing to the northwest and begin the journey.

Nearly a half hour later, I'm standing at the crest of a hill. My nose twitches, picking up the vestiges of an illegal leaf fire smoldering in a nearby yard. The wind bristles through my fur, chill, nearly cold, invigorating. Above me, traffic thunders across the overpass. Below is sanctuary, a perfect oasis in the middle of the city. I leap forward, throwing myself off. At last I'm running.

My legs pick up the rhythm before I'm halfway down the ravine. I close my eyes for a second and feel the wind slice across my muzzle. As my paws thump against the hard earth, tiny darts of pain shoot up my legs, but they make me feel alive, like jolting awake after an overlong sleep. The muscles contract and extend in perfect harmony. With each stretch comes an ache and a burst of physical joy. My body is thanking me for the exercise, rewarding me with jolts of near-narcotic adrenaline. The more I run, the lighter I feel, the pain falling free as if my paws are no longer striking the ground. Even as I race along the bottom of the ravine, I feel like I'm still running downhill, gaining energy instead of expending it. I want to run until all the tension in my body flies away, leaving nothing but the sensations of the moment. I couldn't stop if I wanted to. And I don't want to.

Dead leaves crackle under my paws. Somewhere in the forest an owl hoots softly. It has finished its hunting and rests contented, not caring who knows it's around. A rabbit bolts out of a thicket and halfway across my path, then realizes its mistake and zooms back into the undergrowth. I keep running. My heart pounds. Against my rising body heat, the air feels ice-cold, stinging as it storms through my nostrils and into my lungs. I inhale, savoring the shock of it hitting my insides. I'm running too fast to smell anything. Bits of scents flutter through my brain in a jumbled montage that smells of freedom. Unable to resist, I finally skid to a halt, throw my head back, and howl. The music pours up from my chest in a tangible evocation of pure joy. It echoes through the ravine and soars to the moonless sky, letting them all know I'm here. I own this place! When I'm done, I drop my head, panting with exertion. I'm standing there, staring down into a scattering of yellow and red maple leaves, when a sound pierces my self-absorption. It's a growl, a soft, menacing growl. There's a pretender to my throne.

I look up to see a brownish yellow dog standing a few meters away. No, not a dog. My brain takes a second, but it finally recognizes the animal. A coyote. The recognition takes a second because it's unexpected. I've heard there are coyotes in the city, but have never encountered one. The coyote is equally confused. Animals don't know what to make of me. They smell human, but see wolf and, just when they decide their nose is tricking them, they look into my eyes and see human. When I encounter dogs, they either attack or turn tail and run. The coyote does neither. It lifts its muzzle and sniffs the air, then bristles and pulls its lips back in a drawn-out growl. It's half my size, scarcely worth my notice. I let it know this with a lazy "get lost" growl and a shake of my head. The coyote doesn't move. I stare at it. The coyote breaks the gaze-lock first.

I snort, toss my head again, and slowly turn away. I'm halfway turned when a flash of brown fur leaps at my shoulder. Diving to the side, I roll out of the way, then scramble to my feet. The coyote snarls. I give a serious growl, a canine "now you're pissing me off." The coyote stands its ground. It wants a fight. Good.

My fur rises on end, my tail bushing out behind me. I lower my head between my shoulder bones and lay my ears flat. My lips pull back and I feel the snarl tickling up through my throat then reverberating into the night. The coyote doesn't back down. I crouch and I'm about to lunge when something hits me hard in the shoulder, throwing me off balance. I stumble, then twist to face my attacker. A second coyote, gray-brown, hangs from my shoulder, fangs sunk to the bone. With a roar of rage and pain, I buck up and throw my weight to the side.

As the second coyote flies free, the first launches itself at my face. Ducking my head, I catch it in the throat, but my teeth clamp down on fur instead of flesh and it squirms away. It tries to back off for a second lunge, but I leap at it, backing it into a tree. It rears up, trying to get out of my way. I slash for its throat. This time I get my grip. Blood spurts in my mouth, salty and thick. The coyote's mate lands on my back. My legs buckle. Teeth sink into the loose skin beneath my skull. Fresh pain arcs through me. Concentrating hard, I keep my grip on the first coyote's throat. I steady myself, then release it for a split second, just long enough to make the fatal slash and tear. As I pull back, blood sprays into my eyes, blinding me. I swing my head hard, ripping out the coyotes throat. Once I feel it go limp, I toss it aside, then throw myself on the ground and roll over. The coyote on my back yips in surprise and releases its hold. I jump up and turn in the same motion, ready to take this other animal out of the game, but it scrambles up and dives into the brush. With a flash of wire-brush tail, it's gone. I look at the dead coyote. Blood streams from its throat, eagerly lapped up by the dry earth below. A tremor runs through me, like the final shudder of sated lust. I close my eyes and shiver. Not my fault. They attacked me first. The ravine has gone quiet, echoing the calm that floods through me. Not so much as a cricket chirps. The world is dark and silent and sleeping.
