But how, exactly, do bears live through their seven-month sleep? More specifically, what do they do when ... er ... nature calls?

This is where the "fecal plug" comes into play.

Shorter days trigger biological changes in the bears to prepare them for their hibernation. To prepare for hibernation, many North American bears start making their dens while it's still warm out, in September or October. Cubs often help their mothers build the dens by raking in leaves with their paws.

And all the while, inside their bodies intestinal secretions and cells start to slough off and form a plug, which grows to about 7 to 15 inches long and 1 to 2-and-a-half inches in diameter.

By the time the bears emerge for spring, they have to get ready to eat and poop normally.

So, they get rid of their fecal plug as soon as they leave their den. "By the sixth or seventh month in the den, most of these bears defecate - usually near the den entrance," according to the North American Bear Center. "Fecal plugs have a light odor that is not unpleasant."
