The wolf headed in a direction that it hadn't gone very often. It seemed like the best place to find food tonight. It knew enough to be able to figure out that always hunting the same area meant that there would be less food. It went to a new place every night. Maybe not new to it, but new to the night. The direction it hadn't gone much before regularly smelled like people longer than the others. It had discovered on one or two of the nights that the scent was downright fresh.
Tonight, the smell had faded to an acceptable level.
It started out on it's night rounds with a bit of a happy feeling. Every day that it was away from the zoo, it felt better. Safer. Less likely to be found and taken back. It didn't want to be in that place ever again.
There were trails of other creatures, but it didn't pay any attention to those. Those were the ones that smelled half like animals and half like humans. They weren't prey. They weren't anything to the wolf. It did smell, however, that a rabbit had gone this way not so long ago. Nose to the ground, it picked up the scent and followed it.
