In North America, where the raccoon spends longer or shorter cold-periods in hibernation, it puts on a thick rind. During the winter a raccoon loses up to 50% of its weight in autumn. His tactile and olfactory senses are excellently developed. The well-known dipping of objects into the water, which helped the raccoon to its popular name, it does not do at all in the liberty. He swims very well, but avoids deep water. Raccoons are nocturnal animals. While the male raccoon is polygamous and mates with different females, the female mates with only one male.
