question: Would a bear that's raised domestically, including sleeping indoors, still go through hibernation?
comment: If the domestically raised bear was a polar bear or a grizzly bear it would likely go through a "hibernation" style phase in the winter as a cub and then as an adult kill and eat you and your family. Other bears, like the black bear, or panda bear would likely make a better choice.
passages: In addition to creating nutritional stress, a warming climate is expected to affect various other aspects of polar bear life: Changes in sea ice affect the ability of pregnant females to build suitable maternity dens. As the distance increases between the pack ice and the coast, females must swim longer distances to reach favoured denning areas on land. Thawing of permafrost would affect the bears who traditionally den underground, and warm winters could result in den roofs collapsing or having reduced insulative value. For the polar bears that currently den on multi-year ice, increased ice mobility may result in longer distances for mothers and young cubs to walk when they return to seal-hunting areas in the spring. Disease-causing bacteria and parasites would flourish more readily in a warmer climate.
   In the summer period they feed on blueberries, crowberries, humpback salmon, and steelhead. In autumn, they eat nuts from nut-pines and mountain ash, and fish. In times of famine they eat dead fish or marine mammals, berries, and graminoid vegetation.
   During their time in hibernation, an American black bear's heart rate drops from 40–50 beats per minute to 8 beats per minute and the metabolic rate can drop to a quarter of the bear's (non-hibernating) basal metabolic rate (BMR). These reductions in metabolic rate and heart rate do not appear to decrease the bear's ability to heal injuries during hibernation.
   Hibernacula vary greatly, but are typically:
  
  BULLET::::- Underground (i.e. ground squirrels, mouse lemurs, bears) or in a protected shelter (i.e. bats, bears)
  
  BULLET::::- Concealed
  
  BULLET::::- Attuned to environmental conditions, such as temperature
  
  BULLET::::- Either reused consistently (i.e. bats, ground squirrels) or very rarely (i.e. bears, mouse lemurs)
  
  Section::::Mammals.:Bears.
   BULLET::::- The closely related [[black-tailed prairie dog]] is a "facultative" hibernator.
  
  Section::::Mammals.:Primates.
  
  While hibernation has long been studied in [[rodent]]s (namely [[ground squirrel]]s) no [[primate]] or [[tropical]] [[mammal]] was known to hibernate until the discovery of hibernation in the [[fat-tailed dwarf lemur]] of Madagascar, which hibernates in tree holes for seven months of the year. [[Madagascar|Malagasy]] winter temperatures sometimes rise to over , so hibernation is not exclusively an adaptation to low ambient temperatures.

   They require a proper cycle which contains cooling them in winters. Pair is heavily fed till November and left to hibernate. During their hibernation period you just have to leave a water bowl in their enclosure and a hiding spot. no light or heat source was used in this period.
   Historically there was a question of whether or not [[bears]] truly hibernate since they experience only a modest decline in body temperature (3–5 °C) compared with the much larger decreases (often 32 °C or more) seen in other hibernators. Many researchers thought that their deep sleep was not comparable with true, deep hibernation, but recent research has refuted this theory in captive black bears.
  
  Hibernating bears are able to recycle their proteins and urine, allowing them both to stop urinating for months and to avoid [[muscle atrophy]].
  
  Section::::Birds.
   American black bears were once not considered true or "deep" hibernators, but because of discoveries about the metabolic changes that allow American black bears to remain dormant for months without eating, drinking, urinating or defecating, most biologists have redefined mammalian hibernation as "specialized, seasonal reduction in metabolism concurrent with scarce food and cold weather". American black bears are now considered highly efficient hibernators. The physiology of American black bears in the wild is closely related to that of bears in captivity. Understanding the physiology of bears in the wild is vital to the bear's success in captivity.

  American badgers are generally nocturnal; however, in remote areas with no human encroachment they are routinely observed foraging during the day. Seasonally, a badger observed during daylight hours in the Spring months of late March to early May often represents a female foraging during daylight and spending nights with her young. Badgers do not hibernate but may become less active in winter. A badger may spend much of the winter in cycles of torpor that last around 29 hours. They do emerge from their burrows when the temperature is above freezing.
   The hibernation of this lemur is strongly dependent on the thermal behaviour of its tree hole: If the hole is poorly insulated, the lemur's body temperature fluctuates widely, passively following the ambient temperature; if well insulated, the body temperature stays fairly constant and the animal undergoes regular spells of arousal. Dausmann found that [[hypometabolism]] in hibernating animals is not necessarily coupled with low body temperature.

   There are a variety of different definitions for terms that describe hibernation in mammals, and different mammal clades hibernate differently. The following subsections discuss the terms "obligate" and "facultative" hibernation. The last two sections point out in particular primates, none of whom were thought to hibernate until recently, and bears, whose winter topor had been contested as not being "true hibernation" during the late 20th century, since it is dissimilar from hibernation seen in rodents.

   Badgers begin to prepare for winter sleep during late summer by accumulating fat reserves, which reach a peak in October. During this period, the sett is cleaned and the nesting chamber is filled with bedding. Upon retiring to sleep, badgers block their sett entrances with dry leaves and earth. They typically stop leaving their setts once snow has fallen. In Russia, badgers retire for their winter sleep from late October to mid-November and emerge from their setts in March and early April. In areas such as England and Transcaucasia, where winters are less harsh, badgers either forgo winter sleep entirely or spend long periods underground, emerging in mild spells.
   Looshkin appeared in the first "Bear" comic, in which he had unwittingly forgotten stowing Karl's previous pet dog Marmalade in a closet to protect him from evil bats in the laundry room. As a result, a few days later, Marmalade suffocated and died head-down. However Bear reminds us that Karl's home does not have a laundry room. Looshkin has also been known to have a very vivid imagination, but all of the things he says or does come from his suspected dementia. Looshkin has thought of cloning Bear with a kit that will give him an endless supply of Bear clones on which to waste his days torturing and killing. In Looshkin's words, "An endless supply of Bear fodder!" In another episode he believed a giant squid that he brought home was a tiger.
   The bears went into hibernation after a goodbye dinner at a local restaurant held on New Year's Day and a final appearance at the "mairie" on 7 January, at the end of the Christmas season. Expected to reappear in late 2019, they returned in April.
   Annual breeding cycles sometimes apply to mammals, with regulating environmental effects including seasonal temperature variation and food availability. Migration patterns of a mammal may sometimes govern breeding times. Mammal breeding in the wild sometimes involves the use of maternity dens for birthing and protection of the young. The polar bear is an example of a mammal who uses a maternity den, whose locations are influenced by migration movements of this species to the seasonal Arctic pack ices. In particular, the polar bears who breed in Wapusk National Park need to migrate to the Hudson Bay pack ice.
   Mike once spent 5 days asleep in a badger set for a social experiment. 
   The polar bear ("Ursus maritimus") creates a maternity den either in an earthen subterranean or in a snow cave. On the Hudson Bay Plain in Manitoba, Canada, many of these subterranean dens are situated in the Wapusk National Park, from which bears migrate to the Hudson Bay when the ice pack forms. The maternity den is the bear's shelter for most of the winter.

  Pack members may guard the maternity den used by the alpha female; such is the case with the African wild dog, "Lycaon pictus".

   Norwegian researchers at the University of Tromsø have shown that some Arctic animals (ptarmigan, reindeer) show circadian rhythms only in the parts of the year that have daily sunrises and sunsets. In one study of reindeer, animals at 70 degrees North showed circadian rhythms in the autumn, winter and spring, but not in the summer. Reindeer on Svalbard at 78 degrees North showed such rhythms only in autumn and spring. The researchers suspect that other Arctic animals as well may not show circadian rhythms in the constant light of summer and the constant dark of winter.

  On 4 March 2014, Bryzgalov was traded to the Minnesota Wild in exchange for a fourth-round draft pick. He played well for the Wild down the stretch, posting a 7–1–3 record, and he shared playing time with goaltender Darcy Kuemper in the 2014 playoffs. The Wild defeated the Colorado Avalanche in the first round but lost to the Chicago Blackhawks in round two. Bryzgalov became an unrestricted free agent at the conclusion of the season.

   Grizzly bears hibernate for 5–7 months each year except where the climate is warm, as the California grizzly did not hibernate. During this time, female grizzly bears give birth to their offspring, who then consume milk from their mother and gain strength for the remainder of the hibernation period. To prepare for hibernation, grizzlies must prepare a den, and consume an immense amount of food as they do not eat during hibernation. Grizzly bears do not defecate or urinate throughout the entire hibernation period. The male grizzly bear's hibernation ends in early to mid-March, while females emerge in April or early May.
   An Alaskan brown bear mother named Sky gives birth to two cubs named Scout and Amber in her den on a mountain slope. When April comes the bears will be ready to leave the den. As the bears leave the oncoming summer brings with it a threat of avalanches. The bears are able to avoid disaster. Upon reaching the lush valley below, the cubs meet the other bears, some of which pose a threat to the cubs; among these bears are Magnus, a big healthy male, and Chinook, an older male. The family works together to survive the spring, with Sky keeping the cubs safe from Tikaani, a pesky lone wolf. The cubs get to know how to defend themselves in encounters with Tikaani. Also the family must stay clear of the frequent dominance fights between Magnus and Chinook.
   Polar bears are currently listed as "Rare", of "Uncertain Status", or "Rehabilitated and rehabilitating" in the Red Data Book of Russia, depending on population. In 2010, the Ministry of Natural Resources and Environment published a strategy for polar bear conservation in Russia.

   Between November and February, cubs are born blind, covered with a light down fur, and weighing less than , but in captivity they might be delivered in the earlier months. The earliest recorded birth of polar bears in captivity was on 11 October 2011 in the Toronto Zoo. On average, each litter has two cubs. The family remains in the den until mid-February to mid-April, with the mother maintaining her fast while nursing her cubs on a fat-rich milk. By the time the mother breaks open the entrance to the den, her cubs weigh about . For about 12 to 15 days, the family spends time outside the den while remaining in its vicinity, the mother grazing on vegetation while the cubs become used to walking and playing. Then they begin the long walk from the denning area to the sea ice, where the mother can once again catch seals. Depending on the timing of ice-floe breakup in the fall, she may have fasted for up to eight months. During this time, cubs playfully imitate the mother's hunting methods in preparation for later life.
