While otters are cute and fun to watch in their natural environment, they do not make good pets. Ultimately, they are not domestic animals and fare better in the wild.

Here are some reasons why.

1. They bite.
Otters and humans do not naturally go together. Otters react to humans the way they would to any other strange creature, i.e., they bite. Their teeth are very sharp — watch the way they handle a fish. Now imagine it's your finger or another body part. Ouch!

2. They spray.
Otters mark their territory by spraying, like cats or skunks. An otter living in your home would see your house as its territory. The smell left behind is very musky and smelly, not a pleasant addition to your home.

3. They are nocturnal.
As you've seen with Grace, otters are nocturnal. Most humans are not. Otters need to hunt and swim at night which will most likely make a human's lifestyle very difficult.

4. They need access to a river.
Do you live near a river where the otter can hunt? The otter prefers fresh fish, caught daily. They consume about two pounds of food a day. Also, it would be very difficult to train an otter to return to your home after a night out.

5. They learn survival skills from their mothers.
No matter how much love you give a baby otter, the best way for them to learn how to be an otter is from other otters. The skills they learn from their mothers in the first 18 months of their lives are vital for their survival. They need to learn to swim and hunt in order to take care of themselves. It's very difficult for humans to fill in as a surrogate otter.
