Sleep is a way to restore oneself and replenish the energy that has been used. Some animals in the wild often sleep for a very long time, even for days, in a condition called hibernation. Hibernation allows animals to store food and save energy for months. Scientists have obtained valuable data on the sleep patterns of tree rats, which are commonly used as test subjects in research. Squirrels gather food to hibernate during the winter, but they also sleep a lot outside of hibernation. Active during the day, squirrels sleep up to 15 hours every day. They also tidy up their nests for hibernation, only staying awake for 12-20 hours per week.
