Well, people always say that mother's love is incomparable and second to none. When people say that there are loads of differences between a human and an animal, they forget that both have hearts filled with all the emotions. And especially LOVE.
Look here, a two-year-old chimpanzee named "Do Do" feeds milk to "Aorn", a 60-day-old tiger cub, at Samat Prakan Crocodile Farm and Zoo in Samut Prakan province on the outskirts of Bangkok. The crocodile farm, used as a tourist attraction, houses some 80,000 crocodiles and is the largest in Thailand.
Looking at them just reminds me of the connection between humans and animals. Just like a human feeds a kitten, this chimpanzee is feeding a tiger cub. I hope you understand what and how i mean to connect all these together. It's very rare to see these kind of strange bonds existing at this kind of time in this world.
