The protagonist opens the cupboard in a haunted house and, terror of terrors, there's a rat inside. Everyone involved screams at the sight of the filthy diseased vermin. Except it looks like it's been recently bathed and brushed. And instead of fleeing or acting aggressive, it's looking expectantly at the actors for a treat. In really egregious cases it might even be white or multicolored instead of brown like a wild rat.

This is a Terrifying Pet Store Rat. While the animal in question is often a rat, it also applies to spiders, snakes, and anything else the audience is expected to react with fear or revulsion toward, despite the animal reacting like a pet. Spiders will saunter calmly over people instead of racing along in a panic. Snakes will crawl onto people's shoulders, staring them in the face comically instead of hissing and coiling defensively.

This is generally caused by the fact that wild animals are really hard to work with. A wild rat might panic and flee realistically, but getting it to sit still long enough for the actors to show up is a challenge, as is anything involved in moving it.[[note]]And the SPCA/Humane Society/local equivalent would be likely to object, too.[[/note]] So a tame ball python that barely moves is a better choice than a deadly jungle snake, especially since [[BellisariosMaxim no one will notice the difference anyway.]] Strangely, this often isn't averted with CGI, as fast, complex movements are expensive to animate. Very often crosses over with MisplacedWildlife.

This is a stock feature of horror movies, they often wander in the background for ambiance, act as a CatScare, or provide a WhyDidItHaveToBeSnakes moment when a protagonist has to get past them. In severe cases, the central threat of a horror movie may fall into this trope. The main thing making this trope is that the animal is neither threatening nor believably wild.

Related to RealityIsUnrealistic, in that viewers accustomed to seeing only Terrifying Pet Store Animals on film are often shocked by how tick-ridden, mangy and scarred actual wild animals tend to be.

[[folder: Film ]]

* ''Film/GraveyardShift'', a movie based on a short story about killer rats by Creator/StephenKing, uses several scenes of rats sitting placidly along the rafters staring at the characters in a way reminiscent of ''Film/TheBirds''. Fortunately the movie shifts the actual monster to a giant (animatronic) bat, sparing us from a forced-perspective Terrifying Pet Store Rat as final boss.
* Disney's ''Film/TheHauntedMansion'' movie at one point has the son need to get past spiders to get into the mausoleum. The spiders are harmless tarantulas (orange-kneed) and they're tame enough that he can move them with his hands.
** However, he ''is'' arachnophobic, so no matter what spider they used, he would still be frightened by it.
* Hilariously done in the exploitation film ''The Gestapo's Last Orgy'', where a woman is threatened by being hung over a pit of flesh eating rats... played by gerbils.
--> '''Nazi:''' If I didn't take my hand out, they'd strip it down to the bones in a minute.
--> '''WebVideo/TheCinemaSnob:''' Yeah, sure. If your hands were made of windblown seeds and grain.
* Played effectively in ''[[Literature/RatmansNotebooks Willard]]'', since the rats are ''supposed'' to be tame, well-groomed, and friendly because Willard takes care of them. It's just that they'll kill if they're told to.
* The ''Franchise/IndianaJones'' franchise does this extensively. Especially in ''Film/IndianaJonesAndTheTempleOfDoom.'' Indy and Short Round nearly die while Willie refuses to reach into a crevasse filled with harmless stick insects and millipedes to shut off the death trap they're in.
** Willie freaks out because she's a [[DamselScrappy fussy, high-maintenance]] [[TheLoad load]], not necessarily because the bugs are supposed to be dangerous. Indy isn't fazed by them at all.
** ''Film/IndianaJonesAndTheKingdomOfTheCrystalSkull'' lampshades the use of non-poisonous (or at least less-poisonous) scorpions in movies. Mutt gets attacked by a largeish scorpion, and Indy says, "The bigger, the better...If you get bitten by a tiny one, don't hesitate to bring it up."
** Some of the snakes in ''Film/RaidersOfTheLostArk'' are recognizable harmless snakes of types people keep as pets, though there is at least one actual cobra ([[FreezeFrameBonus behind glass]]). There's also one "snake" being played by a Glass Lizard, which while legless isn't a true snake at all.
* PlayedForLaughs in ''Film/TeamAmericaWorldPolice'' where some "panthers" are house kittens (much larger than the {{Supermarionation}} heroes) with dubbed growls.
* The English-speaking production of 1931's ''Film/{{Dracula|1931}}'' tried to use opossums and armadillos as giant rats.
* ''Film/NightOfTheLepus''. The infamous '''Giant Killer Bunny Rabbits''' movie. The rabbits look like a menagerie straight from a pet store (to be fair, there're only a ''few'' lops) which are mostly shown running through miniature sets in slow motion or in extreme close-up, smeared with red paint and backed by dubbed growling.
* ''Film/TheKillerShrews'' uses [[{{Slurpasaur}} dogs in bad costumes]] to play the shrews. As you might guess from the quality of the effects, the dogs were not trained well enough to ''act'' scary either.
* ''Film/TheStuff'' uses a great dane which is apparently threatening its owner if it doesn't get more of the titular substance. It wags its tail throughout the scene while dubbed in growling plays.
* ''Film/TheAmazingSpiderMan'' uses this with lizards, who lead Peter into the sewers after Conners and participate in a fake out scare where they make Peter think The Lizard is coming.
* ''Film/ChoppingMall'' has snakes and spiders get loose in an actual pet store. They aren't played as dangerous, but they make it challenging for the heroine to stay silent while being stalked by killer robots.
* In the beginning of ''Film/TheMummyReturns'', Evy and Rick are in an ancient ruin and encounter some snakes. They're Terrifying Pet Store Snakes; in an overlap with MisplacedWildlife, some are tricolor milk snakes, which are known for having warning coloration similar to that of venomous snakes but are ''not'' known for living in Egypt.
** The venomous snakes they mimic aren't exactly from Egypt either.
* A whole Terrifying Pet Store Rat ''swarm'' confronts Daniels in ''Film/ShutterIsland'' when he begins climbing the cliff face to the cave. Not only are they obviously well-groomed and curious about his presence, but the first one to appear is clearly ''dropped'' into view of the camera rather than climbing or jumping down to the rock.
* ''Film/{{Cujo}}'' tried to avert this by having the BigFriendlyDog's tail restrained to stop it wagging, which would have made it rather difficult to take it seriously as a savage, rabid monster.
* ''Film/TheFoodOfTheGods'' uses this with its swarm of [[RodentsOfUnusualSize giant rats]]. They tend to stare around in a perfectly tame way looking for a treat. The rats' leader is even a white rat. It doesn't help that since they're just superimposed on miniature sets, they have no reaction to the human actors whatsoever.
* In possibly the UrExample, some of the rats in the 1922 silent film ''Film/{{Nosferatu}}'' were obviously ''hooded'' rats, a pet store variety.
* ''Film/ManosTheHandsOfFate'' has the Master's "devil dog," which on-set was the friendliest dog in the world.
* In ''Film/SilverBullet'', a girl is startled into falling over when a rodent emerges from beneath a garage shelf. Said Terrifying Pet Store Rodent is a ''gerbil''.
* ''Film/ThreeBigMen'' (also known as ''Turkish Spider-Man'') contains what might well be one of the most ridiculous cases ever: man-eating ''guinea pigs''.
* ''Strays'' is about killer housecats. Aside from the cats' "leader", who actually hisses for the camera, the cats just sort of run around the house or sit on their marks. In a few cases they're obviously batting at string just out of view of the camera.
* In TheFilmOfTheBook of ''Film/{{Holes}}'', the deadly "yellow-spotted lizards" are played by bearded dragons, which are harmless and popular as pets. At moments when the lizards have to act particularly menacing, the film averts this trope using CGI; however, in most of their appearances they are clearly Terrifying Pet Store Lizards.
** Likely a NecessaryWeasel in that of the three species that inspired the yellow spotted lizard, the [[http://en.wikipedia.org/wiki/Gila_monster gila monster]], [[http://en.wikipedia.org/wiki/Beaded_lizard Beaded Lizard]], and [[http://en.wikipedia.org/wiki/Horned_toad Horned Toad]], the first two are in fact quite irritable and dangerously venomous, and the horned toad is endangered- putting all three of the "realistic" options solidly out of play. The bearded dragon, however, is neither, and rather closely resembles the descriptions in the book when given a dye job.
* ''Film/TheCraft'' is the king of this trope near the climax when the other witches torment the main character. Her house absolutely fills with piles of harmless snakes, small lizards, scorpions, spiders, and cockroaches that just sort of ignore her as she flees from them. The rats are at least dropped on her from offscreen.
* Whenever we see inside the crazy killer's truck in ''Film/IceCreamMan'', there are white mice and Madagascar hissing cockroaches wandering placidly around the ice cream and bloody eyes.
* For ''Film/DeadlyEyes'' to have rats the size of small dogs on some scenes, they were literally played by small dogs; the filmmakers dressed some dachshunds with specially made ratsuits.

[[folder: Live-Action Television ]]

* ''Shamelessly'' invoked on various AnimalPlanet shows these days such as ''Series/FatalAttractions'' and ''Series/SwampWars'', the latter of which goes on endlessly about the evil scaly monsters infesting the Everglades while treating us to ostensibly terrifying stock footage of a [[RidiculouslyCuteCritter Corn Snake!]]
* There's a History Channel documentary on the Black Death that uses hooded (white with grey or brown heads) rats in its scenes of flea-infested rodents carrying the Plague into port. Granted, they look a bit grubby, but their coat-pattern mutation is still conspicuous and unlikely to survive in the wild. The rats who contributed to the Black Death were black rats (''Rattus rattus'') not brown rats (''Rattus norvegicus'', the rat you're more likely to encounter on the streets or in a pet shop). Arguably a case of a RealityIsUnrealistic, however, as while the Plague was brought in by black rats, rat fleas freely exchange between the two, and the brown rat was more common in Europe even at that time.
* ''Series/LifeAfterPeople'', if not using ConspicuousCGI for the rats.
* On ''Series/CriminalMinds'', some well-groomed rats gather to investigate a bound captive whom the Killer of the Week had left to be devoured alive. They crawl on the bound man's lap and occasionally touch his bare skin with their forepaws, but remain obviously calm and friendly, even when rescuers break in and start shoving them away with an unrealistic delicacy.
* ''Series/{{Bones}}'' uses this from time to time when a corpse is found infested with animals eating it.
** Frequently when they find a decaying body in the sewer covered in rats, none of which show the slightest surprise or interest in the living humans walking about.
** In one episode they find the victim surrounded by possums. Again, no possum shows any hint of non-familiarity with humans.
** In another episode the dead VictimOfTheWeek is surrounded by "feral" stray cats, which sit about and let themselves be picked up by animal control.
* In season 4 of ''Series/TheWalkingDead'', a shadow-hidden figure feeds a live rat to a walker through the prison fence. The rat remains calm, even curious, as it's held up to the chain-link, showing no fear of the walkers ''or'' the human holding it, even when it's being carried by its tail (which ''hurts'').
* On ''Series/CSIMiami'', a man falls from a balcony into a tank full of jellyfish. Wolf identifies the jellies as ''box'' jellyfish and potentially lethal, but they're obviously moon jellies - one of the least-dangerous types - in all the shots where they're not CGI.

[[folder: Western Animation ]]

* PlayedForLaughs in ''WesternAnimation/SouthPark'' when the town is overrun by giant guinea pigs and other "guinea" animals such as rabbits and dogs, the animals in question are simple shots of pet animals shuffling about benignly in cute outfits, which have been digitally inserted into the animation.
** Also spoofed with the Mexican Staring Frog of Southern Sri Lanka, which isn't even a real frog, just a stuffed toy on a string.
