Baby sea otters’ fluff isn’t just adorable, it’s practical: they can’t sink because their incredibly dense hair traps air, making them float. But they still have to be taught to swim and groom themselves, which is more difficult for humans to encourage them to do without an adult otter to show them.
Another reason why raising orphaned otters isn't easy is because they get sick easily due to not receiving antibodies from their mother’s milk, a condition you may be familiar with if you’ve ever had to bottle-feed abandoned kittens or puppies.
