Unique Cat Names: The Rare Ones, With Their Origins

Every "unique cat names" page on the internet has the same problem. It asserts that its names are rare and never shows you what rare means. Rover's list runs to about 400 names, Daily Paws' to 365, and neither attaches a source, a meaning, or a ranking to a single one of them. "Unique" is claimed, never demonstrated.

This page does it the other way round. First, what the word actually measures against: the four published name rankings of the US, the UK, Canada and Australia, and the insurers' own "wackiest names" contests. Then the pools that reliably produce a name you will not hear at the vet's: mythology, literature, the laboratory and the night sky, and a handful of real cats whose names are on the record. Each comes with its origin, and the ones that only look unusual are flagged, starting with Loki. (If your cat's coat is the point, the black cat names page tells the folklore market by market.)

What "unique" is measured against

Here is the honest bar. No country publishes a top 100 of cat names. Every primary ranking we could open tops out between ten and twenty names, all drawn from pet-insurance claims data. A name absent from all four of those lists, and absent from the insurers' own unusual-names features, is measurably rare, because those lists are built from the same underlying data.

Four countries, one verdict. Luna leads everywhere. Milo and Leo trade the male crown. Simba, Bella, Oreo and Mochi repeat across at least three of the four lists. If a name is on this table, it is not what this page is offering, whatever it sounds like.

The Loki test

Loki is the name people reach for when they want "edgy." Norse trickster, Marvel villain, a hard k in the middle. It reads rare.

It is not. Loki sits in the US top 20, the UK top 10 and the Canadian top 10 for 2025. In three of our four markets, a Loki at the shelter is one of the most ordinary cats in the building. The lesson is the page's whole method: a name being mythological does not make it rare. Check it against the rankings first, then decide. Every name below passed that check.

The insurers run their own "unique" contests

The people who hold the data have noticed the demand. Nationwide runs an annual Wacky Pet Names contest; its 2025 cat vote ran from April 15 to 19, and the winner, from Walker, Michigan, was a cat called Wendy's 4 for $4. The other cat nominees on Nationwide's own page: Angry Potato, Beef Stewart, Cattila the Hun, Kirkland Signature Brand, Lando Catrissian, The Megalodon, Pickles of Purrington, Pro Skater Tony Hawk and Purrrsephone.

Those are real, insured, named cats, which makes them the most verifiable "unique" names on the internet. They are also puns, which is a different page: the funny cat names guide covers the mechanics. What follows is the quieter kind of rare.

Mythology: the deepest well

Gods and monsters are not where parents draw their shortlists, so their names stay rare. Egypt has the real cat connection: Bastet was worshipped as a lioness and, later, specifically as a cat, and thousands of mummified cats were buried at her cult centers. One caution before you copy an "Egyptian cat god" list: Mafdet is shown as a feline usually read as a cheetah or serval, and Anubis is jackal-headed. Both are fine names for a cat. Neither is a cat god.

Egyptian

• Bastet (f): goddess of protection and the home, worshipped at Bubastis in the Nile delta, daughter of the sun god Re; bronze votive cats by the thousand survive in her honor.
• Sekhmet (f): the lioness goddess of war, the "Eye of Re," at times identified with Bastet.
• Mafdet (f): one of the oldest deities in the tradition, protector against venomous bites, shown as a feline or a woman with a feline head.
• Maahes (m): lion-headed god of war, son of Ptah and, depending on the region, of Bastet or Sekhmet; one translation of his name reads "he who is true beside her."
• Isis (f): the Greek form of Egyptian Aset, possibly from a root meaning "throne"; goddess of the sky, wife of Osiris.
• Anubis (m): from Egyptian jnpw, read either as "royal child" or "to decay"; the jackal-headed guide of the dead.

Norse

• Odin (m): Old Norse Óðinn, from óðr, "frenzied, furious, inspired," the same root as Woden and Wednesday. The one-eyed god of war, wisdom and death.
• Freya (f): Old Norse Freyja, "lady"; goddess of love, beauty, war and death, who claims half the warriors slain in battle. Already popular in Australia (top ten), so borderline.
• Skadi (f): giantess of winter, mountains and skiing; the reference sources give no root meaning for this spelling, so we do not invent one.
• Idun (f): keeper of the golden apples that keep the gods young; again, no etymology on record.
• Hel (u): ruler of the underworld realm of the same name, Loki's daughter, "queen of the dead."

Greek

• Hecate (f): possibly from hekas, "far off"; goddess of witchcraft, crossroads and the underworld. The black-cat link runs through Galinthias, turned into a cat and taken into her service.
• Selene (f): simply "moon"; the Titan goddess of it.
• Circe (f): possibly related to a word for "hawk"; the sorceress who turned Odysseus's crew into pigs and then hosted him for a year.
• Persephone (f): meaning unknown and probably pre-Greek; the rival theories connect it to words for "destroy" or to a root for "sheaf of corn." Daughter of Demeter, taken to the underworld, returned each spring.
• Nyx (f): "night," daughter of Chaos, wife of Erebus.
• Calliope (f): kallos, "beauty," plus ops, "voice"; the muse of epic poetry.
• Andromeda (f): aner, "man," plus a verb for "to protect, rule over"; the rescued princess, now a constellation and a galaxy.

Celtic

• Brigid (f): Old Irish Brighid, from the root brigā; goddess of poetry, healing, fire and smithcraft, later folded into Saint Brigid.
• Epona (f): Gaulish epos, "horse," plus a divine suffix; her cult spread across the Roman Empire far beyond Gaul.
• Morrigan (f): the Irish war goddess who appears as a crow; Behind the Name states plainly that no definition was found, which is itself worth knowing.
• Cerridwen (f): the Welsh keeper of the cauldron of transformation; recorded only as a variant spelling, no root given.

Literature: names built to be unusual on purpose

T.S. Eliot's "Old Possum's Book of Practical Cats" (1939) is a closed set of fourteen poems, and its opening poem argues that a cat needs three names, one of them known only to the cat. Eliot's own inventions are the most cat-specific literary names that exist, and neither of the big competitor lists mentions one of them.

• Macavity (m): the "Hidden Paw," the master criminal never present at the scene of his own crimes.
• Mungojerrie and Rumpelteazer (u, f): the cat-burglar double act, "knockabout clowns" and quick-change artists.
• Skimbleshanks (m): the Railway Cat who patrols the night train.
• Growltiger (m): the rough Thames barge-cat of "Growltiger's Last Stand."
• Bustopher Jones (m): the "Cat about Town," in white spats.
• Jennyanydots (f): the Old Gumbie Cat.

One more, from a different shelf. Behemoth (u) is the demonic, chess-playing, vodka-drinking black tomcat of Bulgakov's "The Master and Margarita," written between 1928 and 1940. His name is at once the Russian word for hippopotamus and one of the traditional names for a demon in the Biblical tradition, which is a lot of history for a cat who mostly eats pickled mushrooms.

Real cats, on the record

Two documented sources supply names no generator will ever suggest. Félicette (f) is the only cat ever to fly to space: a Parisian stray launched on a French Véronique rocket on October 18, 1963, to 154 km, and parachuted back safely. The French press first called her Felix, after the cartoon, until the researchers confirmed she was female. Guinness World Records holds the entry.

The other is a house in Key West. The Hemingway Home and Museum keeps about sixty cats, almost all descended from a white six-toed cat named Snow White, and names every one of them after a celebrity, a tradition the museum says goes back to Hemingway himself. The current roster on the museum's own page includes Shirley Temple, Hairy Truman, Archie Andrews, Howard Hughes and Rita Hayworth. So if you want a rare name with a paper trail: Truman, Archie, Howard, Rita, Shirley.

Science and the night sky

Element and star names are rare on cats and rich in stories, which is the combination this page is after.

• Cobalt (u): from German kobold, "goblin." Harz Mountains silver miners blamed the ore for wrecking their yield and their health, and named it for a goblin; George Brandt isolated the element in 1733.
• Titanium (u): named in 1795 by Martin Klaproth after the Titans of Greek myth, "on the fanciful notion of the Titans as sons of the earth"; nobody isolated a pure sample until 1887.
• Neon (u): Greek neos, "new," coined in 1898 by Ramsay and Travers the moment they identified it.
• Nebula (u): Latin for "mist, cloud, smoke," applied to the sky around 1730; some of those "nebulae" turned out to be whole galaxies.
• Quasar (u): shortened in 1964 from "quasi-stellar radio source," and the model for "pulsar" four years later.
• Vega (f): from Arabic for "the falling vulture," the fifth-brightest star in the night sky.
• Sirius (m): Greek for "scorching," from its ancient rising at midsummer. It is also the Dog Star, the brightest star we can see, which makes it either a mistake or a joke. We vote joke.

What to take away

• No country publishes a top 100 of cat names: the US, UK, Canadian and Australian rankings stop between ten and twenty names, all from pet-insurance data, and that is the honest bar for "unique."
• Luna is number one in all four markets; Loki sits in the US top 20 and the UK and Canadian top 10, so a mythological name is not automatically a rare one.
• Nationwide's 2025 Wacky Pet Names winner was a cat called Wendy's 4 for $4, from Walker, Michigan, the most verifiable "unique" name of the year.
• T.S. Eliot's 1939 "Old Possum's Book of Practical Cats" supplies fourteen poems of invented cat names (Macavity, Skimbleshanks, Jennyanydots) that no competitor list uses.
• Félicette, launched on October 18, 1963, is the only cat ever to fly to space, per Guinness World Records; the Hemingway Home in Key West names about sixty cats after celebrities.
• Cobalt comes from the German word for goblin, Titanium from the Greek Titans, Neon from "new": the periodic table is a name list with stories attached.
