Y'know, I can understand most unappealing-looking food (eg., sea urchin, most fermented foods from a culture other than your own, etc) because at some point hunger got the best of someone, they ate it and lived to tell the tale.
But civet fermented coffee? You'd have to be pretty desperate for that cup o' Joe to be like "well, I'm out of beans, the cat ate my stash but... :checks litterbox:"
(yes I know they're not really cats)
