Well, for the sake of argument, we'll assume that:

1) The rescue team's escape tunnel won't reach the trapped miners for 90 days;

2) The miners have found a fully functional gas cookstove that is ventilated via a small pipe extending to the surface;

3) Joe happens to be an expert butcher, and by some strange coincidence has a selection of his razor-sharp knives and cleavers in his tool belt; and

4) That a mile-deep pit for waste disposal lies adjacent to the site of the trapped miners.

Here, Fluffy.... come on, that's a good doggie...

Okay, so you have some fixation for gnawing on Fluffy. (LOL!) When to do the deed? You know that you're trapped there for 90 days, with no water, a possible lunatic with cleavers (he might bear watching, dontcha think, in case you start looking tasty?), and a (gasp!)ventilation shaft to the surface (through which some nutritional substances and water just might be able to pass). When do you need the calories? At 10 days? At 30 days? At 60 days? It would be a better idea to convince your roomie with the cleavers to widen the ventilation shaft and cut steps up so that the now skinny you and roomie can climb out faster rather than waiting 90 days for somebody to rescue you. Macgyver probably would figure out some way to use the gas cooker, too!
