Short excerpt of Simon Worall's "Yes, Animals Think And Feel. Here's How We Know":
"Many people think that empathy is a special emotion only humans show. But many animals express empathy for each other. There are documented stories of elephants finding people who were lost. In one case, an old woman who couldn’t see well, got lost and was found the next day with elephants guarding her. They had encased her in sort of a cage of branches to protect her from hyenas. That’s seems extraordinary to us but it comes naturally to elephants.

People have also seen humpback whales help seals being hunted by killer whales. There is a documented account of a humpback sweeping a seal on its back out of the water, away from the killer whales. These things seem extraordinary and new to us because we have only recently documented these incidents. But they have probably been doing these kinds of things for millions of years."
Carl Safina even wrote a book about "What animals think and feel", here is a record of one of his lectures:
Humans need to start meeting animals on an equal footing. We need to live in harmony with the nature, instead we try to reign over our planet which will lead to many crisis in the near future.
