History Main / AlienAnimals

If the alien doesn't naturally resemble an animal but has disguised itself as one through VoluntaryShapeshifting, then TheDogIsAnAlien. If the alien looks like an animal but isn't on Earth posing as one, it's probably an IntelligentGerbil.

* Also in ''Literature/{{Animorphs}}'', domesticated dogs are the product of Pemalites bonding their souls with wolves before they became extinct. So that counts. Sort of.

* ''WebOriginal/HowToHero'' deals with these in their entry on [[https://howtohero.tumblr.com/post/169761172692/pets "Pets"]].

* Similarly averted in ''Film/{{Zathura}}'', where It's Not A Goat ... and it's not on Earth, either.

'''Carol:''' Hmm...the cat? This isn't what you are afraid of, is it?\\
'''Talos:''' That's not a cat...that's a flerken!

-->-- ''Film/CaptainMarvel''

* In one ''WesternAnimation/DarkwingDuck'' episode ("Twin Beaks"), the hero gets help from aliens that looks exactly like Earth cows -- though this is not exactly this trope, since it is probably only these cows that are aliens, not all cows on Earth.
** Possibly a ShoutOut to a ComicBook/FantasticFour story in which Reed hypnotized some shapeshifting aliens into [[ShapeshifterModeLock mode locking]] themselves into cows.

There's an animal on this planet that's always looked harmless - rabbits or mice or squirrels or hamsters, it doesn't matter. One day, you'll be walking your corgi dog [[FluffyTheTerrible Mr. Flufferkins]] along and suddenly he'll look up at you and say, "Thank you, human, for this relaxing walk and all those times you've scratched my chin, but I'm afraid the [[ScaryDogmaticAliens Nogov 10th Brigade]] is coming here in [[TwoOfYourEarthMinutes five of your Earth minutes]] to [[EarthShatteringKaboom get rid]] of this [[InsignificantLittleBluePlanet small blue planet]] and replace it with a transgalactic outlet mall. However, this is good news: [[BadNewsIrrelevantNews you can spend your last five minutes secure in the knowledge that everyone will be getting cheaper outlets soon]]. Well, except the human race, of course, but these things have to be built. Goodbye." And then he disappears before your very eyes, along with every other corgi on the face of the Earth.

* In ''Series/DoctorWho'', it's the [[spoiler:BEES! Okay, not all of them, but a lot of them were and they were going home, back to the planet Melissa Majoria]].
** Also cats. Possibly, it's not clear whether they came from Earth and were kept as pets elsewhere or vice versa.
** In "Survival," the Cheetah People's minions the Kitlings look exactly like Earth cats, except that they can teleport.

* A ''ComicStrip/{{Garfield}}'' cartoon suggests that cats are invaders attempting to subjugate humanity, and that they are responsible for certain seemingly-mindless actions of dogs and lower-class humans.
* In one ''ComicStrip/MandrakeTheMagician'' story, Narda has a dream (OrWasItADream?) about finding out that cats and dogs are two warring alien species; the ones on Earth were spaceshipwrecked here, and have exploited the dumb native humans (specifically, cats the females, dogs the males) to survive in comfort without their technology.
* In '80s ''Ziggy'' Sunday strips, the titular character's pet parrot turned out to be an advance scout for an alien invasion force. This idea since seems to have been dropped.

* Goose the cat from ''Film/CaptainMarvel'' turns out to be an alien who can use tentacles to eat people and objects several times larger than itself.

You've just encountered the Alien Animal. These [[AliensAndMonsters aliens]] don't have [[LittleGreenMen green skin]] or [[RubberForeheadAliens rubber foreheads]], they just look exactly like a specific type of animal. Maybe they make up the entire population of that animal on Earth or only part of them. Sometimes they're leaving Earth because they have knowledge about the impending [[TheEndOfTheWorldAsWeKnowIt end of the world]] and sometimes they just like [[AliensStealCable watching television]]. Just [[MST3KMantra relax]] and go with it.

* In one ComicBook/FantasticFour story Reed Richards hypnotized some alien shapeshifters called the Skrulls into thinking they were ordinary Earth cows. Years later those alien cows got mixed in with some Earth cow and some were slaughtered for beef. The alien flesh though gave some people a virus that [[CursedWithAwesome shapeshift their bodies into deadly weapons and detect hidden skrulls]] and it would also eventually kill them. The best part? [[ParanoiaFuel There is no way of telling which cow is a Skrull until you eat it.]]

* ''Film/TheCatFromOuterSpace.'' The lead cat arrives in a spaceship and falls for one of the native cats. Oh, and this is a ''live-action film'' otherwise starring ''humans.''

* A Creator/SpiderRobinson story in the [[Literature/CallahansCrosstimeSaloon Callahan]] series reveals that we find cockroaches distasteful because they are the degenerate descendants of an evil alien race of overlords.

* In one ''ComicStrip/{{Mandrake The Magician}}'' story, Narda has a dream (OrWasItADream?) about finding out that cats and dogs are two warring alien species; the ones on Earth were spaceshipwrecked here, and have exploited the dumb native humans (specifically, cats the females, dogs the males) to survive in comfort without their technology.

* Staryu and Starmie from ''Franchise/{{Pokemon}}'' are implied to be from outer space. They're [[StarfishAliens starfish with mysterious psychic powers.]]

* The species of highly intelligent (and highly cuddly) cats from ''{{WesternAnimation/Futurama}}''. [[CatsAreMean They're here to enslave and kill humanity, natch]].

* On ''WesternAnimation/TeenTitans,'' an alien is visiting Earth when its intelligent pet, which looks like a green dog, escapes. Meanwhile [[{{Animorphism}} Beast Boy]], who can turn into a green version of any animal, is impersonating a dog. HilarityEnsues.

* ComicBook/KryptoTheSuperdog is (usually) a dog from Krypton and looks like an earth native dog even if he normally doesn't resemble a specific breed, though some artists make him look a lot like a yellow lab with abnormally pale coloring.

* ''VideoGame/BaldursGate'': Boo, the miniature [[AttackOfThe50FootWhatever giant space hamster]]. At least if you take [[CloudCuckoolander Minsc's]] word for it.

* In the Film/MarvelCinematicUniverse, Rocket is an alien who happens to look like a raccoon. This is an AdaptationSpeciesChange from the comic, where he's a normal raccoon [[UpliftedAnimal altered by aliens]].

* Similarly averted in ''{{Zathura}}'', where It's Not A Goat ... and it's not on Earth, either.

* Can be created in ''{{Spore}}''; you can make creatures that look rather like real animals...or you can make StarfishAliens.
