Sapient Pet

Pet characters in most works are Nearly Normal Animals, whether with the ability to talk in Animal Talk or not. These animals, however, are just animals, not intelligent beings like humans.

This trope, on the other hand, is about pets who are intelligent and able to interact with their owners (usually a human, but can be a human-surrogate animal or alien) on the same level. Sometimes these pets are actually smarter than their owners and choosing to hide it, other times they are open about being sapient beings and are accepted as part of the human world as well as their own world.

Pets that shift between humanoid and "pet" forms do not go here and should be under Anthropomorphic Zig-Zag instead.

There are several variations on this


 * Sapient Pets That Masquerade as Normal Pets Around All Humans: These beings choose to hide that they are at least as smart a human. Sometimes this involves a disguise as a normal animal, other times the entire species plays dumb to stay hidden. The examples including Broken Masquerades would belong here, as a broken masquerade would suggest that there is a masquerade. Unlike the other variants, it doesn't involve animals being treated as pets and people simultaneously.
 * Sapient Pets That Masquerade as Normal Pets Around Some Humans: Unlike the above variant, these beings can behave like humans around some humans but not around others. Unlike the above variation, they are treated like either like people if only those who know are around or as pets by if humans who should not know they are sapient are around. They do not shapeshift to do this, they simply modify their behavior. Shapeshifters that turn from humanoids into pets and back in order to hide go under Anthropomorphic Zig-Zag, not here.
 * Openly Sapient Pets: These are intelligent beings that don't hide that they are intelligent. Some of these beings are treated like non-sapient animals despite their sapience, and others are treated as the sapient beings they are. They may be accepted by humans around them or humans may react in horror. Either way, these beings are not afraid to "be themselves".

This trope also includes sapient animals and aliens who are service animals, lab animals, livestock, circus animals, or zoo animals.

Not to be confused with Anthropomorphic Zig-Zag. Sister trope to Sapient Steed. See also Civilized Animal, Funny Animal, and the Sliding Scale of Anthropomorphism. Related to Amplified Animal Aptitude and Intellectual Animal. Many Weasel Mascots fit this trope too.

 * Toto in the later Oz books. Someone notes that of all the animals in Oz -- including many imported from outside its borders -- Toto is the only one that doesn't speak.  At which point Toto admits that he can speak, but didn't want to for fear that Dorothy would stop treating him as a pet and stop pampering him.

Tabletop Games

 * In the Star Wars RPG Sourcebook, "Cracken's Rebel Operatives", Moff Jarnek's Cool Pet Daerlar is a Covallon. Because Covallon walk on all fours, it isn't widely known that they're a fully sentient race. Dearlar chooses to keep this fact secret rather than seeking his freedom because

 * It turns out that "void mages" can only summon humanoid familiars, so by definition the familiar of a void mage is always a sentient pet.
 * Luna and Artemis from Sailor Moon can talk and have powers, but only do so to the Sailor Scouts.

Comics

 * Salem Saberhagen from Sabrina the Teenage Witch is a warlock transformed into a black cat as a punishment for trying to take over the world. Around other witches and warlocks he is (mostly) treated as a person but around Muggles he acts like a normal pet cat owned by Sabrina. The premise is the same in the live action TV show.

He sometimes wears manipulator "gloves" that let him operate complex machinery. In the second issue's opening, he breaks the fourth wall to give a synopsis of the first issue, and snarks at the reader, "That's right. A talking cat. You are quick." Why Raul is sapient, and how many other sapient animals may exist, are never addressed. When he first spoke in front of main character Reuben Flagg, Flagg's only reaction was to think, Talking cat. Right. without real surprise.

Film

 * Gremlins has the Mogwai which, when maltreated, become the even more intelligent and dangerous Gremlins.

Literature

 * In the Star Wars book The Approaching Storm, a Gwurran named Tooqi actually asks to become Barriss Offee's pet. His logic is that pets get free food, protection from predators and the affection of their masters, in exchange for a relatively minor amount of work. Certainly a better deal than living wild in a cave with the rest of his tribe.

 * In Dwarf Fortress it's trivial to do a Game Mod to turn any sentient species into one which can also be a pet, just by adding the [PET] tag to the right place in the right plain-text file. Of course, since the game designer never intended sentient species to be pets, this can lead to strange results, like a sentient pet being elected mayor.

Webcomics

 * The comic Housepets is about a group of Funny Animal housepets who act more like children to their human families rather than pets.
 * Keidran from Twokinds, by some of the nicer humans (of course, they're also seen as a source of cheap labour by more dickish humans). The Keidran are officially slaves.

Western Animation

 * My Little Pony: Friendship Is Magic has different levels of sapience among pets.
 * Dragon cub Spike is sort of like an adopted son or little brother to Twilight Sparkle, but in some ways he is much like a pet; Twilight Sparkle's friends know him, he very much enjoys the attention he gets from them, and like a loyal dog he often works for them and tries to protect them, and he can be very dangerous when his behaviour gets out of control. Yet Spike also talks, and has some ideas that, had they been listened to, the ponies could have avoided a lot of trouble.
 * Angel Bunny doesn't talk, but clearly understands what Fluttershy is saying to him, and often tries to communicate his response in non-verbal ways.
 * This example has a lot of Furry Confusion going for it. Some of the non-pony animals, like sheep, are shown to be able to talk but for whatever reason, are treated like animals. The pets of the ponies, (like Angel Bunny, Opal for Rarity, and Owlicious for Twilight Sparkle) act more like their real life counterparts (except Angel, as stated, often pantomimes his wishes). It's hard to say what is and isn't sentient in that universe, considering Rule of Funny comes into play so often.
 * Gromit the dog from Wallace and Gromit wavers between Openly Sapient Pet and Sapient Pets That Masquerade as Normal Pets Around Some Humans.
 * Roddy from Flushed Away (also by Aardman Animations).
 * The farm animals from Rock-a-Doodle.
