I'm unable to post photos here, but on TV I've seen dogs raising tigers (up to a certain size anyway; after that, the dogs are lunch) and cats raising chicks (as in chickens).
Even more amazing to me is when prey animals chase off their attackers. I saw a show last year that had footage of a pride of lionesses that had brought down a wildebeest. They were busy choking it to death and chewing on it, when, unbelievably, a pack of a dozen or so other wildebeests approached the lions and drove them off. The injured animal got up and rejoined the herd. To face down a predator that terrifies them in order to save one of their own is, to me, an incredible display of courage and compassion.
Several years ago, I saw a show about a dairy farmer in England who liked to pet his cows and give them treats. One day, while the farmer was mowing grass, his nasty-tempered bull charged him and injured him badly. His cows immediately came to his aid, forming a circle around him to protect him from further harm. The farmer was able to crawl, his circle of cows moving with him, to his house to call for help.
My parrot has a full range of emotions, from outrage to utter contentment. Whenever I do something that angers him (usually taking away something he shouldn't be chewing on), he climbs to the highest perch in his cage and deliberately turns his back on me. Talk about a snub! The dubs could learn some new shunning tactics from him.
It's always intriguing to me when animals act "out of character." I don't usually ascribe human emotions to animals, but they are far more complex than we give them credit for.
