Cats Are Magic

Throughout history, cats have gone paw-in-paw with the supernatural. In Ancient Egypt they were considered to be sacred to the goddess of the moon, Bast; in medieval Europe they were tied to witchcraft; in Japan and Russia they are heralds of good luck; in the Muslim world, they are regarded as Born Lucky, benevolent djinni, while in other places they are harbingers of misfortune. In Western culture, cats are purported to have nine lives, and black cats in particular carry associations with witchcraft and both bad and good luck.

Unsurprisingly, when people write about cats in works with magic, cats tend to have magic too.

Because All Witches Have Cats, cats are almost certain to make an appearance in a work with witches, and more often than not, these felines will possess unusual abilities. Even in media without witchcraft, cats alone will sometimes be able to perform supernatural feats while other animals will be extremely mundane. If any one animal has the ability to be understood by humans or to use human speech fluently, chances are that it's a cat. A person will often choose the form of a cat when using magic to disguise him or herself as an animal. Similarly, using transformation as a form of punishment often results in a feline transformation. Sometimes their magic might appear in a Follow the White Rabbit form.

Usually a magical cat will be intelligent, but even non-sapient cats can have magical powers. Wittingly or not, cats may even be using their abilities to keep The Masquerade. Despite all this, cats are not often Bond Creatures, except maybe to witches in fluffiest of works. This is perhaps due to their reputations of being aloof and independent. This trope may mean a cat is an Evil Sorceror if used in a story where Cats Are Mean.

 * At one point in The Mummy 1999, a normal cat is able to ward off Imhotep because "cats are the guardians of the underworld". This is exploited only the once, because Imhotep completes his regeneration soon after and becomes immune to whatever the cat would supposedly have done to him.

 * Un Lun Dun, by China Mieville, subverts this by making cats the most stupid and least magical of all animals. Dogs, foxes, various birds, and even fish are shown to be sapient and able to cross the boundaries between worlds, but cats are too concerned with looking cool to learn anything of value.
 * A black cat in Neil Gaiman's Coraline can talk in the Other Mother's universe, and acts as a sort of Mentor towards the heroine.
 * Neil Gaiman's short story The Price is about an otherwise ordinary black cat who, on a daily basis, protects the narrator's home from a demonic entity. The black cat gets more and more beat up with every fight, and when he fails to fight the demon, the narrator's household is afflicted by numerous misfortunes. Yeah. Gaiman has a thing for black cats.
 * In Lloyd Alexander's, Time Cat, all cats have the ability to travel to any place they choose, in any point of time they choose. This is said to be the reason why they can vanish mysteriously in small rooms.
 * Discworld's Death is very fond of cats and gives them all nine lives. That said, the only cat who is really magical is Maurice, from The Amazing Maurice and His Educated Rodents. He gained sapience and speech by eating a rat who had, in turn, also eaten some magical garbage.

 * In the Polish short story "Because the cat" a company designs computer systems that allow children to learn at a fantastic rate, creating associations after a single exposure to a given situation. Unfortunately, it goes bankrupt as several of the devices break down - the system responsible for recognising just what is the right association suffers a self-inflicted Logic Bomb, as it tries to make sense of the reality around it. One of the children was damaged more than others - the boy has a pet cat and the faulty system has built his entire logic around the animal, attributing all that is happening to its behaviour. The characters consider the child a hopeless case and consider euthanizing him - until he gets bored and uses the cat to Reality Warp himself out of the hospital.

 * Subverted in Mercedes Lackey's Diana Tregarde story "Arcanum 101." When Di is observing the house of someone she believes may be involved in black magic, she sees a cat wander past the house with no reaction... and thinks to herself that this doesn't mean anything because, superstitions notwithstanding, cats are too self-absorbed to notice magic that isn't affecting them directly.

 * In the Toby Daye series all cats are loyal to the local King of Cats, aware of magic, and much smarter than they let on. And this is the ordinary non-magical cats. There are also the Cait Sith, who are cat fae and outside the normal fae laws for being cats.

Myth and Legend

 * Ancient Egyptians worshiped the goddess Bast, who was cat-headed and held cats to be sacred. At some points in ancient Egypt, harming cats carried the death penalty.
 * In Japan cats are said to give good fortune, which is why you see welcome/lucky/beckoning cats (white ceramic cats with a gold coin and one raised paw) in some establishments. The lower paw (which is often holding a coin) is to protect money, and the raised paw draws money in.
 * A black cat crossing your path is said to be bad luck in most of continental Western Europe
 * On the British Isles Black Cats have better press for some reason and are usually associated with good luck
 * A woman with a cat, especially a black one, will have more suitors.
 * In Scotland, the arrival of a strange black cat to a house is supposed to signal good fortune for everyone in the household.
 * The urban legend that shelters won't allow black cats to be adopted around Halloween in case they're killed and torture ritualistically (the former is true, the later is unsubstantiated).
 * Ship's cats (especially black ones) were said to be lucky by sailors, although pirates often believed that a ship which had a black cat walk on then off was doomed to sink. The ascribed good luck, at least, is probably more attributable to the fact that ships traditionally have rat problems than any magic, however.
 * Many modern Pagans, including Wiccans, hold cats in high esteem. In Wiccan rituals, it is believed a cat can walk through a magic circle without breaking it, since cats can walk through spiritual/magical borders. Another animal, like say a dog, would break the circle and thus dispel any magic.
 * Cats are believed in some cultures and traditions to be able to see spirits and ghosts.

 * Rose, who is arguably the most magical of the four kids in Homestuck, prototyped her dead cat Jasper to her kernelsprite, and also made a genetic sequence using the letters MEOW (instead of the typical GCAT) which can be spliced with other DNA to create godlike entities.
 * After the universe is rebooted, we meet an actual GCat, likely made with a BARK sequence. The G, of course, stands for God, since, as a First Guardian, GodCat is pretty much omnipotent.
 * Errant Story has the flying black cat, Ellis. He's extremely resilient to offensive magic and can also talk... which is not necessarily a good thing.
 * Poe from Neko the Kitty Comics can speak English, levitate, and has minor telekinetic powers.
