No Refrigeration Needed.

Playing Possum-

Surprised this guy early one evening when I rounded the corner of the house. He just slowly rolled over onto his side, face contorting into this rictus grin.

Unresponsive to gentle prodding with stick.

And when I say stick, I mean the kind that fell off a tree.

I envision some sort of clockwork or wind-driven device on a tripod placed over the animal that would give it a poke at semi-random intervals. In this way the meat could be kept fresh indefinitely.
