Otters are nocturnal wild animals and domesticating these animals might be a daunting task. Some otters produce and spray a pungent smell, just like the skunk. These animals need a lot of water, preferably rivers, and love to be outdoors all the time. They love to eat fish and can eat up to 15-25% of their body-weight in a day. They are nocturnal animals which love to spend up to 5 hours looking for food. Although there have been cases of some otters being taken in as pets yet they do not make good pets.
