I have seen my guinea pigs mourn, and even become severely depressed after the death of their cagemates so I have no problem believing that humans can’t be the only species that feel attachment and compassion.
The following is a series of photos by a photographer chronicling the sad love story of a couple of barn swallows. It is said that people all over the world have cried after seeing these pictures, and that the French newspaper that originally ran the photos sold out on the day it first published the story.
I couldn’t help but be reminded of the famous YouTube video of the dog that rescues another dog from a highway in Chile. I remember shedding quite a few tears after first seeing this video, and wondering how many humans would do this for a fellow human being.
