If you met this nekomata in the wild when she or her companions are not in danger, you would think she’s completely harmless. After all, she is about the size of a house cat, with fluffy white fur and black markings, and the only thing that marks her as supernatural is that she has two tails instead of just one. However, if you happen to threaten her or her loved ones, she will grow big enough to carry up to three people on her back, grow fangs, and flames will spur from her flanks and limbs. She can also fly and is completely immune to fire. She’s also immortal, or close to immortal, as she is older than the jewel of souls.

Kirara is a perfect pet for those who love the outdoors as she can bring you back to your camp or home if you get too tired to do it on your own. She’s also extremely fierce and will protect you from all harm. Not only that, her warm and cuddly fur will comfort you whenever you need her.

Cerberus, better known as Kero or Kero-chan, is another pet that, at first glance, seems completely harmless. We meet him in his borrowed form when he looks like a cute plush lion cub with big ears, beady eyes, and very small wings. Sure, he can fly and has a large knowledge of magic, but you can hide him easily in your backpack with none being the wiser. His true form, on the other hand, is a majestic maneless lion with giant wings, wearing a metal breastplate with a ruby in the center. He can't sustain that form for long, but when he does, you know things are going to get serious.

Kero-chan is an excellent pet for anyone who can’t have pets due to space or rental agreements. Can’t have an animal in your dorm? No problem, Kero-chan looks like a plush toy and no one has anything against plush toys. As an extra advantage, he’s also quite smart so if you bribe him with candy he’ll be more than happy to help with a late night cram session for those annoying final exams.

Foxes are incredibly cute. Some people describe them as cat software running on dog hardware and that’s a nice comparison as they seem to be a mix of the best of both pets even if one must be aware that they’re not really domestic animals and keeping one in a house requires a lot of special care and preparation. That said, Osaki-ko, or O-chan as he’s known to his owner Tamaki Kasuga, is a very special fox, as he’s actually a type of fox spirit known as an osaki-gitsune: a fox spirit born from the tail of a nine-tailed fox who brings wealth and protection to the families they live with.

O-chan, in particular, is a gorgeous white fox and appears to be almost a cub despite the fact that he’s probably older than the whole cast put together. He has a blue seal on his forehead, which distinguishes him from a normal white fox, and also has deep blue/green eyes and two tails with blue ends. O-chan likes to travel on Tamaki’s shoulder and make her smile by mewing. If you are the kind of person who likes peace and calm, O-chan is the perfect pet for you.

The first time we see Pen Pen on screen, we’re as confused as Shinji Ikari. After all, no one would’ve expected to see a penguin living in a small apartment, much less one that enjoys beer, watching tv and reading the newspaper. At times, one could even say that Pen Pen is more of a roommate than a pet for Misato, especially as he seems to be the only one in the apartment whose life and mental health is not a mess. While he seems to be quite resistant to heat as he can take hot baths, he prefers to sleep in a second fridge that Misato has just for that purpose.

Penguins are adorable flight-less birds that we usually only get to see in zoos or in nature documentaries. But there's something about them that fascinates us: It may be the fact that they seem to be absolutely fearless when it comes to human contact or their seemingly endless quirks such as falling in love with anime cut-outs or giving rocks as engagement gifts. So Pen Pen would be the perfect pet for someone who is a bit strange or likes weird things. At the very least, he's the perfect drinking buddy for when all your friends are busy.

Imagine you could have a small cute hamster whose fur and body are mostly transparent like a soap bubble, can change shapes in a limited way—including covering your whole body to protect you if need be—is very smart, and you never have to clean up after. If that sounds like a perfect pet, well, that's what the Kiryu Biotech Research Facility scientists were thinking when they created the prototype for a pet for kids. Aiko Tachibana’s father decided to surprise her with one on her birthday right before the accident that took his life, and little after that, the Burst happened so Aiko is the only girl in the world with one, and she decided to call him Gummi, for his similarity to a Gummi bear.

Gummi is a dream pet for anyone who has allergies since he’s perfectly hypoallergenic. He’s also perfect for those who have germ phobia because he can effectively make sure nothing but oxygen gets to their owner by turning into a full-body bubble. Because of how little extra care they need, besides affection and playtime, he’s also a great pet for those of us who are a bit messy. One of the best examples of artificial life in the series and a pet we all wish we could have.

When a sentient penguin hat revives your dead sister while possessing her to give you orders, you don’t really stop to question the whys at that precise moment. If said hat also gives you a penguin of your very own to help you find what you need to keep your sister alive, well, that's also an advantage. That’s what happens to siblings Shouma, Kanba and Himari during a visit to the aquarium when Himari dies of a seizure. And so, now they have three penguins in their care, #1, #2, and #3. The big advantage is that they’re not normal penguins and thus, are invisible to everyone but the siblings.

Mawaru Penguindrum is a very weird show, and one of the weirdest elements of it are the three penguins. They don't really affect the plot that much and are usually in the background doing their own thing. This is more noticeable with #3, who stays at home to take care of Himari, while #1 and #2 go with the brothers to help them in their “missions”. They are pretty much comic relief, but let’s be honest, who wouldn’t want a cute invisible penguin to make them laugh when life gets hard?

Kyuubey, the incubator, is the perfect example of something being too good to be true. As a pet, he sounds amazing: he looks like the cutest, fluffiest plush toy that is a mix between a cat and a rabbit. He’s immortal and has been around earth for a long time. He can be invisible when needed, and so no one can tell you you can’t have a pet. Kyuubey also speaks, so he can be a conversation partner if you are feeling a bit lonely and your friends are away. The only downside is that he loves to be cryptic, and will continuously try to convince you to make a contract with him to be a magical girl.

If you don’t mind having to carefully consider everything he says, or the fact that at times he has a different understanding of the world, Kyuubey is still a good pet. Without going into much detail, it is possible for Kyuubey to be nice to those around him. He’s just like a pet tarantula, or venomous snake: Pretty to look at, interesting to have, but you need to be incredibly careful when handling him or you’ll pay some dire consequences.

There’s one particular downside of supernatural pets we haven’t mentioned yet: They are very sensitive to being abandoned. Kuro, a Cat Sith, is a very good example of what happens when someone doesn’t take this into account. He used to be worshipped as a deity by silk farmers and took care of them, protecting them from all harm. That was until the farmers started moving, and soon, left his temple abandoned. Feeling alone, Kuro took his more demonic form as a cat taller than most buildings and went into a berserker rage until Father Fujimoto adopted him as a friend. For a long time, Kuro remained in his cute cat form, drinking sake with Father Fujimoto when he came to the city. And then Father Fujimoto died and no one thought of telling Kuro, making him despair again until Rin came along.

If you love cats you will fall in love with Kuro immediately. He looks just like a small black cat with a grey patch of skin on his chest and right front paw, two half moons on top of his head and two tails. He prefers his small size as he can ride on Rin’s shoulder, and he acts like a cute cat too, from his love of sunny spots to his unending loyalty to his human. Once you meet him, you want to make sure he never loses a human again because his sadness is overpowering and very relatable to anyone who has lost a pet.

Who wouldn’t like to have a loyal and fierce dragon as their pet? Charizard, the third evolution of the first generation Pokemon is still one of everyone’s favorites for that reason. Not only he is still one of the most powerful Pokemon you can get, but he is also one of the coolest either in his normal version, his shiny version, or the Mega evolution. As Charmander, he starts like a small cute dinosaur, which is also an incredible pet to have; and as he grows and becomes more powerful, he gets to be a giant force to be reckoned with.

The thing is, choosing just one is a bit unfair since with about 806 different Pokemon, there’s one for every taste in a very literal way. One could say that we’d be really happy if Pokemon were real because everyone could have the most adorable and perfect pet for themselves no matter what their tastes, allergies or activities were. Most Pokemon are more partners in crime than pets and help their humans in their jobs. But still, Charizard was one of the first, one of the most badass and that is why he gets to represent his whole franchise.

Totoro is a huge cat-like creature, fluffy and gentle that lives on the forest near the Kusakabes’ new home. At first, only Mei, the youngest daughter of the family, can see him, and he protects her when she wanders into the forest following other smaller spirits like him. He waits a bit before he allows Satsuki, Mei's older sister, to see him as well and since she's kind to him, he also gives her gifts that lead Satsuki and Mei in some magical adventures. It's hard not to love him at first sight because he's very nice to those who need his help, and whenever you are alone, he may be there just to keep you company.

Totoro is so adorable that even those who haven’t seen the Hayao Miyazaki film know his shape and he is the Ghibli Studio’s official mascot. Because, who wouldn’t love to fall asleep on his soft big belly and then travel with him inside the Cat bus? Many years have passed since the movie premiered, but Totoro is still beloved by most anime fans who would love to have a neighbor Totoro of their own.
