Editor’s Note. At his grandparents home in Springfield, Illinois, Pat Bowe puts together a multi-story McMansion for his newly arrived hamster. After thinking about different names (Margueritta and Moesha were rejected), Pat’s second hamster Marvita joins the earlier hamster Minnie Moo in the high life. Watch the new arrival Marvita roll in the ball on the floor and go in circles in its own private treadmill. Note the large rodent house Pat puts together has its own separate exercise wing. Watch Minnie Moo do laps there to the strains of jazz pianist McCoy Tyner playing George Gerschwin’s Summertime.
