I think it’s important to know that humans treat these animals like absolute shit to literally drink their shit that doesn’t even taste good, but it’s expensive
I remember reading that wild animals just eat the best cherries, it has nothing to do with the digestion. The caged animals are just making shit beans.
A big part of this story is that the civets are very picky and only eat the best coffee cherries. There might of course also be other factors, but the pickiness is key.
