A lot of people want to say "these other animals cannot possible be like us in any way" as an attempt to say humans are vastly different than the other animals. The reality is that we are still mammals, still animals, every trait we possess is seen in at least a few other animals thus other animals will think and feel much like what we do.

The cute thing about this is that is shows empathy develops in even smaller brains as strongly as in our larger brains. Meaning it's likely far more common in the animal kingdom than we once thought.
