Bears in Hibernation

[mallory]

What is the name for the plug which a bear inserts into its rectum prior to hibernation

[amarillis]

Bears don't get rid of wastes in the months that they hibernate. The urine is broken down inside their bodies and reused as protein to help the bear keep its muscles healthy. A 'plug' of feces, hair, and nest stuff forms at the end of the bear's digestive tract. This comes out when the bear leaves the den at the end of the hibernation period. Disgusting, but interesting.
