Defecated Decaf

By now most java enthusiasts have heard of Kopi Luwak, a supposedly superior coffee obtained by grinding the beans after they have traveled through the digestive tract of an Indonesian civet cat. Further web research led me to find a similar coffee product that is created when the beans are ingested and regugitated by a species of Vietnamese weasel. If coffee snobs are willing to pay enormous sums for these beans (over $400/lb.), then why not put the rest of the animal kingdom to work looking for even better brews. Why not feed coffee beans (after testing for potential toxicity by using escalating doses)to various zoo and farm animals? After recovering and processing the beans, panels of taste testers could then determine which species possessed the ideal digestive apparatus to produce the most flavorful and aromatic beverage. If a suitable domestic animal (say cow, sheep, or guinea pig) were identified, then mass production would even be feasable, creating an extra source of income for our farmers and ranchers. Perhaps there are other vegetable products which can be similarly "improved" by a trip through the alimentary canal, such as cocoa beans, vanilla beans, or other edible nuts, berries, or grains.
