High on the hog is where the loin chops, the most valuable cuts, come from

true, and this may well be the source of part of the idiom, but it also seems likely that the "hog" referred to is the early british colonial coin (bermuda/hog-money/YCLIU), and that living high off of the hog refers to the "high life" resulting from having money to burn? the phrase "whole hog" likely stems from the same source.

and shouldn't this be in animal safari?
