Did you know that you feel the same emotions animals have when they see each other? Or is it the other way around? Apparently, animals are a lot like us in their own unique ways.

Some of these creatures are even capable of making lifelong commitments to their partners. Some have eternal bonds to their mothers, generally showing the same kinds of behavioral responses humans do under certain situations.

Even cats, often considered the epitome of aloofness and emotionlessness, can express certain important feelings towards humans in the cutest of ways.

So, all the traits we consider human, it would seem, can be found in many animals in nature. They might not all be present in a single animal species, but when you consider a broad range of animals, you will find that animals do the very same things we do.

If you think this is all made up, consider the following 20 interesting facts about animals.

1. Sea otters hold hands while they are asleep to prevent drifting apart while floating.
