detects animal death

I got out of the car and felt something wrong. An uneasy feeling ran over me, prickles of sensation along the nape of my neck and against my spine.
I stood there for a minute, frowning, while Rudolph and Stallings got out of the car. I looked around the neighborhood, trying to pin down the source of the odd sensations. The leaves in the trees, all in their autumn motley, rustled and sighed in the wind, occasionally falling. Dried leaves rattled and scraped over the streets. Cars drove by in the distance. A jet rumbled overhead, a deep and distant sound.
"Dresden," Rudolph snapped. "Let's go."
I lifted a hand, extending my senses out, pushing my perception out along with my will. "Hang on a second," I said. "I need to ..." I quit trying to speak, and searched for the source of the sensation. What the hell was it?
"Fucking showboat," Rudolph growled. I heard him start toward me.
"Hang on, kid," Stallings said. "Let the man work. We've both seen what he can do."
"I haven't seen shit that can't be explained," Rudolph growled. But he stayed put.
I drifted across the street, to the yard of the house in question, and found the first body in the fallen leaves, five feet to my left. A small, yellow-and-white furred cat lay there, twisted so that its forelegs faced one way, its hindquarters the opposite. Something had broken its neck.
I felt a pang of nausea. Death isn't ever pretty, really. It's worst with people, but with the animals that are close to mankind, it seems to be a little nastier than it might be elsewhere in the wild kingdom. The cat couldn't have reached its full growth, yet - maybe a kitten from early in the spring, roaming the neighborhood. There was no collar on its neck.
I could feel a little cloud of disturbance around it, a kind of psychic energy left by traumatic, agonizing, and torturous events. But this one little thing, one animal's death, shouldn't have been enough to make me aware of it all the way over from my seat in the police car.
Five feet farther on, I found a dead bird. I found its wings in two more places. Then two more birds, without heads. Then something that had been small and furry, and was now small and furry and squishy - maybe a vole or a ground squirrel. And there were more. A lot more - all in all, maybe a dozen dead animals in the front yard, a dozen little patches of violent energies still lingering. No single one of them would have been enough to disturb my wizard's sense, but all of them together had.
So what the hell had been killing these animals?
I rubbed my palms over my arms, a sickly little feeling of dread rolling through me. I looked up to see Rudolph and Stallings following me around. Their faces looked kind of greenish.
"Jesus," Stallings said. He prodded the body of the cat with one toe. "What did this?"
