what did the old man eat??

Didn't he have a bunch of cats? Supposedly cat tastes just like chicken.

I think he was cracking nuts when Logan and Jessica arrived. Foraging would account for most of it, I'm sure. He might have had access to some bunkers of SPAM and twinkies, too.

He's had many years to learn how to survive.

Judging by the final scenes he was about to embark on an all you can eat pussy buffet...if you catch my drift.

Fishes, planktons, proteins from the sea? (or whatever the Jiffy-Pop robot said...

they showed some walnuts i think
