Raised by Humans

Alice is on a date with Bob. She tells him that she has an adopted son and that he's "different". Bob asssures her that he loves kids and that he'd love to meet hers. Alice takes Bob to her home and introduces him to her son...who turns out to be a chimpanzee.

Essentially, this is an inversion of Raised by Wolves. Only, instead of animals raising people, people raise animals. This is especially common in Funny Animal shows, books, and movies. How well the animal intergrades into human society also varies as well. Sometimes, the animal still acts like an animal, but views the humans that raised it as family and will protect them. Other times, the animal may end up acting like a human and/or even believing they are human until shown otherwise.

Most of the time, this is simply due to a human character adopting a non-human baby to care for. However, though rarer, some fictional stories actually have the non-human baby's biological parent(s) actually be human (It's best not to think about it too hard)

See also Muggle Foster Parents, where the adopted child is not an animal, but isn't a normal human either.

Anime and Manga

 * Son Goku from Dragon Ball. He's an alien (Saiyan, to be specific) who ended up being raised by an elderly man named Son Gohan (Whom he'd end up naming his son after). Too bad Goku accidentally killed his "grandpa" one night during a full moon by turning into an Oozaru and crushing the old man.

Comic Books

 * Superman himself. He looks human, but he is an alien raised by humans Ma and Pa Kent.

Films -- Animated

 * Tod from The Fox and The Hound is raised by an old widow woman after his real mother had been killed by hunters.
 * The Country Bears had a young bear cub that was raised by humans. He didn't even know he was a bear until his adopted brother pointed it out.
 * Both Megamind and Metro Man are aliens who landed on earth as babies and were raised by humans.
 * A variation comes from the movie Brother Bear. Kenai (after being turned into a bear) becomes something of a surrogate brother to an orphaned cub named Koda. Ironically
 * In Watership Down, General Woundwort was orphaned as a baby when a weasel killed his mother, and was taken in by a kindly local man. It's likely his later hyper-aggressiveness stems from the trauma of watching his mother being eaten and the stress of growing up apart from other rabbits.
 * Blu, the main character of Rio, is a blue macaw who was smuggled out of Brazil and found by a little girl in Minnesota, who raises him to adulthood. Because of his sheltered upbringing, he has a hard time coping in the wild, especially since he never learned to fly.

Films - Live-Action

 * Rise of the Planet of the Apes.
 * In the film version of Stuart Little, Stuart was an orphaned mouse adopted and raised by humans.
 * The original novel, however, has him be an anthropromorphic mouse whose birth parents just happen to be human for some unexplained reason.
 * "It's very unusual for an American family to have a mouse," says the doctor, as if it were commoner in other nations.

 * The titular character in Hellboy is a demon raised by humans.

Literature

 * In the Earth's Children series Ayla invents the concept: first she takes in a foal when she kills its mother for food, then she takes in lion cub which gets injured, then a wolf cub when she kills its mother.
 * Hagrid attempts this with a baby dragon in the Harry Potter series. He ends up letting Norbert go to live in a dragon preserve in Romania.
 * Douglas Preston's novel, Jennie is about a chimpanzee who's raised as a human by an American family, and actually believes herself to be a human.
 * In Turtledove's Worldwar Series, two Lizards are raised by one of the human characters.
 * In The Demon Trilogy, the demon Hnikarr possessed the body of an unborn infant. Taking possession of such an unformed mind provided a way for Hnikarr to keep the body from deteriorating (the original occupant being in no way equipped to resist), but it also caused Hnikarr to lose his memory and limited his mental development to that of his body (the reason that demons in the setting normally avoid possessing humans younger than sixteen). The mother of the possessed baby then ran off with him, with the end result that he was Raised by Humans.
 * In Tales of Kolmar, an herbalist found a baby dragon mourning her mother and took her in for a year. The only other human she saw was his sister. He named her Salera, and she believed for a while that one day she'd lose her wings and stand on two legs, but figured things out on her own eventually.

Video Games

 * Giegue/Giygas from EarthBound was an alien raised by humans.

 * Subverted in an episode of Adventure Time where Finn The Human tries to raise a baby Jiggler. His heart's in the right place, but he doesn't know how to take care of the Jiggler and nearly kills it. He ends up bringing the baby back to its mother.
 * Subverted with Brian from Family Guy. While he is treated like part of the family, he's only considered the family pet rather than a surrogate son to Lois and Peter.
 * Played straight in the episode "Brain's Wallows and Peter's Swallows" in which a bird makes a nest in Peter's beard (It Makes Sense in Context) before being frightened away. The bird had laid eggs in said beard which hatch and Peter ends up taking care of them until they are old enough to take care of themselves and fly away.
 * Cow and Chicken in which two humans (well, actually, two pairs of human lower bodies to be specific...but, eh, close enough) are the proud parents of a, well, cow and a chicken.

Real Life

 * Many people who have pets do see them as part of the family and view them as their own children. This is especially evident with families with "empty nest syndrome" who often get a pet as a sort of "surrogate child".
 * An episode of Animal Planet's Fatal Attractions featured a man who raised a lion cub as if it were his own child. Said cub in question ended up mauling his actual human daughter. The lion in question had to be shot and killed by the very man who raised her in order to save his daughter.
 * Another episode featured a couple who raised a chimpanzee, Moe, and treated him as if he was a surrogate son to them. Unfortunately different chimps ended up ripping the owner's face off when he was returning Moe to a California wildlife sanctuary.
 * A similar incident happened with the infamous "Travis The Chimp", who attacked a friend of his owner and was shot by police.
 * Several chimpanzees were raised as humans by scientists, who were trying to teach them human language. Project Nim is a documentary about such an experiment. Nim was dressed in human clothes, diapered, and even breastfed by a woman.
