Some years back while cleaning out the trunk of our car, I found a nest of baby mice. Wanting to also remove the mother, I decided to put them in a gallon milk jar. A small stick was leaned up against the jar so the adult mouse could get to the top of the jar and jump in to get to her babies. I figured she would get in and be unable to get out. When I returned, all of the babies were gone. Never figured the mouse could jump straight up that high, or scale the inside of the jar to get out. How would you figure she got them all out?
