Grizzly bears and black bears generally do not eat, drink, defecate, or urinate during hibernation. Bears live off of a layer of fat built up during the summer and fall months prior to hibernation. Waste products are produced, however, instead of disposing of their metabolic waste, bears recycle it.Sep 18, 2019

Do hibernating bears poop?
According to the National Park Service, black bears and grizzly bears generally do not urinate (pee) or defecate (poop) while hibernating. During hibernation, poop (and other stuff) builds up in the bear's lower intestine to form a fecal plug. The intestinal walls absorb all the fluid.
How do bears keep from pooping during hibernation?
So there you have it, bears don't poop during hibernation because their bodies continue to shed cells, creating poop even without food. As this happens, hair, plant matter, and other things get eaten as the bear grooms itself.
Do animals in hibernation poop?
Even those hibernators that don't eat or drink anything at all sometimes defecate and urinate during hibernation (metabolizing stores of fat does produce waste), but these animals expel only a tiny amount during hibernation. Hibernating bears, on the other hand, can go the whole winter without going to the bathroom.
Do bears wake up to pee during hibernation?
A) Bears hibernate during winter, but aren't sleeping the whole time. Hibernation for bears simply means they don't need to eat or drink, and rarely urinate or defecate (or not at all). There is strong evolutionary pressure for bears to stay in their dens during winter, if there is little or no food available.
Can humans hibernate?
Human hibernation doesn't exist for many reasons, but the reason why is not quite as immediately obvious as you might think. Hibernation is a response to cold weather and reduced food availability.
What happens to bears when they hibernate?
Hibernating bears enter a shallow torpor with a decrease in body temperature of only 10 degrees. It's metabolism and hear rate slows down. But it doesn't need to eat, drink or pass waste. In order to survive, fat in the bear's body breaks down into water and calories for the body to use.
Do black bears hibernate?
Black bears are not true hibernators. Instead, they experience what is often called denning, ursid hibernation or carnivore lethargy. This period of reduced activity occurs in all black bear populations.
Can you wake up a hibernating bear?
Hibernating bears are immobile, but they can awaken easily (a fact that makes studying bear hibernation quite difficult). Whereas hibernators like ground squirrels lower their body temperature to almost freezing, bear body temperatures only drop about 6 degrees Celsius.
Can you wake up a bear in hibernation?
For hibernating animals like black bears, waking up early can be disastrous. For famous hibernators like black bears, predators such as mountain lions can present a threat during their winter rests. A more common one, though, is humans—not because they will attack a bear, but because they can wake it up.
