POCATELLO, Idaho (AP) -- Fred Risinger never gives his eastern Idaho bar patrons a last call - but then his customers are mice. Some are teetotalers who eschew the mouse-sized shots of alcohol they can obtain at any time simply by pressing a lever in their cage. Others Risinger describes as "your wine with dinner mice." And some are raging alcoholics, downing, in human terms, several fifths of liquor each day.
Risinger, an Idaho State University professor, said what makes the alcohol cravings in the individual mice different is the same thing that makes the alcohol cravings in humans different: genetics.
