Did anyone read Desparate Voyage? Enroute from Panama to Austrailia, the author/sole oceanic voyager, was given pigs and chickens from south pacific islanders.
He nurtured them until prepping for consumption - one at a time. No refrigeration onboard, so he ate well for spurts at a time. When his food ran out, his wise pet rat which lived in the bilges - jumped ship before becoming the next meal.
Guess if I was that rodent, I'd rather drown than become rat sushi too.
