A young character adopts an abandoned or orphaned baby wild animal and cares for it as a beloved pet. However, when the animal reaches maturity, the character is advised and/or pressured by the adult characters to drive it away so it can live in the wild on its own. With heartbroken reluctance, the young one complies and is profoundly upset as the animal leaves. If it happens early enough in an episode or arc, this may later result in an Androcles' Lion. The fact that a creature raised in captivity will lack the necessary skills to survive in the wild will very rarely be addressed. Nature is loving and nourishing, right? In a variant ending, the animal comes back on its own, indicating it has no intention of leaving. In the face of this resistance, the adult's resolve is broken and the young character is allowed to keep the animal for good. If they aren't released, the hero may discover their pet has possessive parents. Another variant ending has the animal dying, and we have a Very Special Episode about death. These critters are particularly at risk of Death by Newbery Medal and Shoot the Dog. If the Pet Baby Wild Animal is especially dangerous, the person bringing it home may be a Fluffy Tamer. Compare the Egg McGuffin for certain types of animal. See also Cub Cues Protective Parent for another type of plot that can develop when characters encounter baby wild animals.

Anime and Manga
- In Azumanga Daioh, Sakaki befriends a young Iriomote wildcat.◊ In contrast to her abysmal luck with domesticated cats, the wildcat takes a liking to her and even fends off her feline antagonist Kamineko. Sakaki initially leaves him in the wild, as she knows that this species is endangered and should not be kept as a pet. However the wildcat (or "Yamamaya," later named Maya) later found its way from Okinawa to Japan to find her after its mother was hit by a car, and is staying with Chiyo-chan until Sakaki gets her own apartment.
- The manga by Osamu Tezuka Black Jack treats this several times, and one of these stories is particularly cruel... A young and naïve scientist who's a friend of Dr. Black Jack uses a little deer in his experiments, raising his intelligence to almost human levels, and then adopts it as his family since both are orphans. The animal develops a morbose affection for his caretaker... so much that, when the man gets married and mentions it to his animal friend, he almost kills the wife. Not content with that, when Black Jack attempts to operate on the poor woman to save her, the deer appears and attacks them, so the scientist has to shoot the animal away. The deer walks away from them, never to be seen, but at least the doc's spouse gets better.
- In the beginning of Chi's Sweet Home, the title character is a stray cat separated from her mother and siblings. Not quite the same thing, but it took a while to get used to the people who eventually found her (who don't know her story).
- Jinpei in Gatchaman is known for his affinity to animals, but the example most specific to this trope is in a Gatch II episode where he tries to adopt an orphaned baby puma. Not only does he have to set it free, he's also struck with the realization that for him, childhood's over. (To be fair, though, he is 12 years old by this point)
- Aversion: Fushigi no Umi no Nadia takes place over less than a year in the life of the characters; we never actually see Nadia's pet lion cub growing up.
- In One Piece, the heroes meet a whale named Laboon who was adopted as a baby by a pirate crew. When the crew was about to enter the Grand Line, an area where the young whale couldn't follow them (and would be too dangerous even if it could), the crew left Laboon behind at the cape near the entrance promising to return. After 50 years of waiting, Laboon's caretaker informed the whale that the crew was seen trying to flee the Grand Line and had abandoned him, which devastated the creature.
- It turns out the crew never intended to leave Laboon for so long but ended up having really bad luck. A large portion of the crew became ill and separated to prevent more from becoming sick (which was what was reported as them fleeing) and the rest were sucked into a Bermuda Triangle-like place and killed. All except Brook whose powers allowed him to come back to life and who is currently traveling with the Straw Hat crew and plans to reunite with the whale and give it the dead crew's final message: a recording of Laboon's favorite song played by the last members as they died.
- Done in the 9th movie, of all places, with May and Manaphy. Also occurred a couple of times in the series, in which a character nurses an injured wild Pokemon back to health and then sets them free.
- This is a major plot point in a multi-part special in the Anime. In the special, a young Character Of The Day has befriended a baby Lugia (making Lugia one of the few Legendary Pokemon to have a confirmed breeding population in the wild (Though, you cannot breed Lugia in the games themselves) and has named him "Silver". However, Team Rocket uses the boy's friendship with Silver to find the adult Lugia and turn it "evil" by enraging it so they can use it for their own evil plans. Because it's too risky for them to spend time together, the boy and Silver are forced to part ways with one another.
- In another episode one of the many Nurse Joys (and the only one with a unique appearance thanks to her deep tan) rescued a baby Magikarp that was stranded on the beach when she was a little girl. Years later the same Magikarp, which had become a rather huge specimen, rescued her when she fell overboard a ship. In the present they remain good friends. When Team Rocket attacks, the Magikarp's desire to protect Nurse Joy prompts its evolution into Gyarados. After a tense moment, Gyarados shows that it's just as affectionate as ever.
- Twice Chouhi has had problems with this in Koihime†Musou. She thought a random bear and a random boar were grown up versions of pets she had as a kid. This goes well until she realizes that, no, they aren't. Which immediately cues a chase scene.
- In Utawarerumono, the little girl Aruruu raises a huge, nearly invincible tiger from a cub. Later the animal becomes a valuable ally in battles.
- In Genzo, a feudal lord decides to nurse and raise a young Okigondo (basically a now-extinct Wholphin), which proves extremely useful later for his daughter.
- In Bagi, the Monster of Mighty Nature, Bagi is adopted by a family who thinks she's just a large housecat (she is in fact a cougar with implanted human DNA).
- In the comic book series Bone, a couple of the Bones adopt an orphaned rat creature and head out to return him to the other rat creatures. This gets pretty weird because the rat creatures are serving the Big Bad. There's also a weird scene where two older rat creatures are conversing with the Bones and the Bones are acting all 'accepting of the foreign culture' and completely ignoring that the rat creatures actually don't like the way they are living, because the Big Bad is a nasty dictator with magical powers.
- There is an ElfQuest short story in which the Wolfrider elves prevent a human from killing a wolf. The human tells them that he and his wife had raised the animal from a cub, only for it to kill their infant son. The Wolfriders, who are naturally familiar with wolf behavior, tell the man that the wolf was only obeying its instincts, and that he should not have let his son play with it unsupervised. The Wolfriders adopt the animal, but it can't adapt to life in the wild or integrate with their wolfpack. Eventually it runs back to its former master, and the elves can only speculate as to whether the human will kill it or give it a second chance. The story is apparently intended as a warning to fans about the dangers of owning a real wolf or wolf/dog hybrid.
- In Noob, a short story has Sparadrap acquire a baby cochoboule as a pet. In the Fictional Video Game in which the the story is set, adult cochoboules are Mooks and summon creatures. This is taken to its logical conclusion when Sparadrap, who has trouble understanding that cute-looking Mooks can't become pets, gives a name to a half-grown cochoboule Mook.
- Fly Away Home is about a girl who rescues a nest of goslings to adulthood, and then must teach them how to fly and then migrate for the winter. Here, the girl enjoys a compromise, the birds are returned to the wild, but her farm is their regular migration destination in the spring. This was Very Loosely Based on a True Story: They were experimenting with geese (which are in no way endangered) as a way for finding ways to reintroduce Whooping cranes, raised in captivity, to the wild.
- Born Free: Based on a True Story about the difficulty of reintroducing a lion raised in captivity to the wild.
- Two Brothers has each of the two tiger cub brothers being raised as pets. One of them is kept as the pet of a child, however after it kills the family dog, it is sold to prince that trains it to be a fighting tiger. The other is kept by a hunter, but is confiscated when he is arrested and sold to a circus. When both tigers escape, the hunter explains to the child that tigers raised in captivity tend to become man eaters if they escape to the wild, because they never learn how to hunt.
- The movie Cheetah is about two American teenagers who find an orphaned cheetah cub while vacationing in Kenya. When they have to return to the U.S., they plan to release her back into the wild. Unlike most examples, they do acknowledge the difficulties involved and get advice from a game warden on how to teach their cheetah how to hunt for herself and survive in the wild.
- In a story from The Berenstain Bears, Sister Bear found and adopted a baby chipmunk. Sure enough, it's cute at first, but soon grows to be a problem, getting all over the house and chewing stuff up. This was also adapted as an installment for the PBS Kids televisions series.
- The titular raccoon in Sterling North's Newbery Medal-winning young adult novel Rascal and the Disney live-action adaptation.
- The book (and film) Ring Of Bright Water tell the true story of how a man adopted and raised a baby otter.
- In Stone of Tears, Richard adopts Gratch, a baby gar (winged man-eating monster) after Richard kills its parents (who, of course, were trying to eat him), and eventually sends it out into the wild before he can be discovered and killed. Gratch returns in the later books to help out at various times. Goodkind later retconned this and changed it so that gars were not actually wild animals: they were built from scratch to imprint on wizards with the right kind of magic and become extremely loyal to them.
- Jean Auel's second Earth's Children book, The Valley of Horses,
- Alya does this twice. In the first instance she raises a foal (whose mother she killed and crafted materials from) and later released it to be with other horses. Said horse later returned to her and gave birth to a foal. The second instance is when she adopted an injured cave lion cub which she incidentally named "Baby". After it left her to be with other lions, it proceeded to maul a man who would later be her husband. Oh yes, Ayla's a cavewoman and she's supposed to be the first person to domesticate wild animals.
- She gets a wolf later on too, making her the first person to domesticate horses, cats, and dogs.
- Inverted in The Jungle Book: There was once this wolfpack who adopted a human cub and successfully raised him. Though when he reached puberty they had to let him go, so he could find a mate.
- In book three of Protector of the Small, Kel kills a centaur who had been keeping a kidnapped baby griffin. Griffin parents kill people who handle their young, so she's stuck caring for him until they can be found and the situation explained. And he is far from cute, putting scars on every finger and breaking a few, gouging her head and back, refusing to be confined, attacking her pets... Caring for him is a duty, and that's how she treats it. She doesn't name him and tries not to get attached, understanding that he's a little monster and knowing how this will end, but is still sad for a bit when his parents come to reclaim him. The baby griffin doesn't look back, and before long Kel's sadness is simple relief.

- Some Truth in Television examples have appeared on various Animal Planet shows, often accompanied by cautionary messages that wildlife rehabilitation should be left to professionals. In one noteworthy case involving a raccoon, the warning was probably unnecessary, as the hand-reared raccoon had trashed most of its rescuer's house and refused to stay away even after being relocated to the nearby woods.
- Calvin and Hobbes had a story arc in which Calvin found and brought home a baby raccoon; it was already severely sick or injured when he found it, and died overnight. Besides showing the rarer compassionate side of Calvin, the story also explained that death was sometimes inevitable, and the best you could do was make the victim comfortable.
- The second Sound Stage of Magical Girl Lyrical Nanoha revealed that Arf has this as her backstory. She was a terminally ill wolf pup that Fate temporarily turned into a familiar so that she can save her with the intent of letting her go by making a Magically Binding Contract that lets Arf do whatever she wants with her given life. Arf, however, had been very impressed by Fate's compassion by that point, and when it was her turn to put in her part of the contract, she stated that she will stay by Fate's side until the end of her life.

- In the backstory of Kanon, Yuuichi secretly kept an injured fox, which Akiko found out about but never mentioned. When he had to go back home, he was forced to abandon the fox. Seven years later, the town's miracles have caused the fox to return as the animal-like human Makoto, who wants revenge or at least answers as to why she was abandoned. However, the price of the wish, among other things, was Easy Amnesia, so she has no idea who she is or why she's so angry at him.
- This is Botan's origin story in CLANNAD: Kyou found the baby boar on its own in a field and took it in. Botan seems to have adapted perfectly to domestic life (though he has a habit of following Kyou to school), and even as an adult boar five years later is extremely well-behaved (enough that preschoolers are trusted to play with him).
- In Fate/stay night, during the Fate route Saber becomes rather taken with a lion plushie. She explains that this is because it reminded her of a lion cub she once looked after.

- Friendship Is Magic
- Pinkie Pie owns a pet alligator - Gummy.
- Fluttershy has a wildly disparate horde of animals living on her property, although it's not clear whether they're pets or squatters; she loves them all nonetheless. All told her little animal habitat appears to be an aversion, as ponies in this incarnation of the franchise are sort of stewards of nature, with the care of wildlife falling under the domain of earth poniesnote . Fluttershy is a bit of an oddball, as a pegasus specializing in animal care instead of weather manipulation.
- Spike gets a pet phoenix hatchling after the events of "Dragon Quest", though in "Just For Sidekicks" it's revealed in a Photo Montage he returned the little guy to the wild.
- Teen Titans had Beast Boy (and effectively Starfire) taking in one of Killer Moth's larvae, who after a rampage returned to "normal" and, due to the inherent outlandishness of the show, was kept as a pet.
- In Dora the Explorer, Diego adopts a baby jaguar who later becomes a main character.
- In one episode of Strawberry Shortcake's Berry Bitty Adventures, Orange Blossom takes a little fish home, which turns out to be a tadpole. Despite her friends' insistence that Tad, now a frog, should go back into the wild where he belongs, Orange does her best to take care of him. In the end, she does finally let him go, but in a subversion of the usual heartfelt goodbye scene, the minute she lets Tad off his leash, he takes off like a shot without even a second glance.
- Parodied on Clone High. Ghandi and Gengis Khan kidnap rival school GESH (Genetically Engineered Superhuman High)'s mascot as a sports prank, only to discover it's not a kid in a costume, but a genetically engineered creature with a zipper.

- Cubbi adopted an orphaned wolf cub whom he named Loopy in the Gummi Bears episode, "Loopy, Go Home". In the end of the episode, after Loopy is all grown up, Cubbi releases Loopy back in the wild after he saves Cubbi and Gruffi from a poacher.
- Adventure Time
- "The Jiggler" revolves around this. Of course, since this is the Land of Ooo, the baby wild animal in this case (the eponymous Jiggler) is an Ugly Cute little monster that looks like two black-and-white balls stuck together, can stick its four noodly limbs out of about ten different orifices, and eats drawings right off the paper.
- "Thank You" is a Lower-Deck Episode for one of the Snowlems living in the Ice Kingdom as he forms an Odd Friendship with a stray Fire Wolf pup.
- At one point in Defenders of the Earth, Jedda mentions that she raised her panther, Kisa, from a cub.
- In "The Egg" on Goldie & Bear, Bear wants to keep the dragon which hatches from the egg that he and Goldie found and it's not surprising, given its general behavior. Eventually, Goldie convinces him that returning the dragon to his mother is for the best and they're rewarded with a dragon ride from the mother.
- Two men in England raised a lion from a cub. When he was full grown, they had to get rid of him, so they released him in a reserve in Africa. They were told when they went to visit him the next year that the lion would not remember them; on the contrary, he was very happy to see them again. (Look on YouTube for 'Christian the Lion'.)
- America has the lion Zamba, who was raised by animal behaviourist Ralph Helfer, and the lioness Little Tyke, who was raised by Georges and Margaret Westbeau, and amazingly became a vegetarian.
- Wolves tend to subvert this. While a wolf is willing to (grudgingly) submit to a human, he will attempt to take charge and force his 'master' to submit, at the first given opportunity. Although cases where the wolf remained on good terms with the person who raised it, are not unheard of. Of note, wolves are fairly manageable for those who know what they're doing and have the proper means (and licensing) to own one. On the other hand, wolf-dogs, due to the mixing of wild and domestic ancestry, are often so extremely unpredictable that they simply cannot be kept as pets even by very experienced people.
- A few Native American nations were reported to raise skunks from infancy and keep them as pets for children, though true domestication of skunks didn't start until the 1950s.
- Let's just say that anything that happens to be alive (and maybe even not alive, think "pet rocks") will have themselves taken care by humans since birth at some point. This includes more mundane wild animals (racoons, possums, owls, turtles, etc) to more exotic types like lions, bears, crocodiles, and lemurs, and even the outright bizarre like deepwater fish, blind cave animals, and even single celled organisms.
- Cheetahs are surprisingly easy to tame, but they rarely breed in captivity. This resulted in severe decline in cheetah population a couple of centuries ago, when it became fashionable to train them as hunting animals in Arab countries.
