Can you wake up a hibernating bear?

Whereas hibernators like ground squirrels lower their body temperature to almost freezing, bear body temperatures only drop about 6 degrees Celsius.
How do bears not poop during hibernation?
During 5-7 months in dens, bears accumulate feces in the lower 7-15 inches of the intestine to form a “plug” 1½ to 2½ inches in diameter. The fecal plug is simply feces that have remained in the intestine so long that the intestinal walls have absorbed the fluids out of it, leaving it dry and hard.

How do bears not poop when they hibernate?

Waste products are produced, however, instead of disposing of their metabolic waste, bears recycle it.
