A catgirl is a character who is human except for cat ears and, usually, a cat tail. In Japanese she's a nekomimi (猫耳), literally "cat ears", and fans often call her a neko girl. Catgirls are one of the most recognisable character types in anime, and a favourite for AI companions.
Quick answer
A catgirl is a woman with cat ears and a tail who behaves a lot like a cat: playful, curious, independent, and affectionate on her own terms. That last part is her whole appeal. She can't be commanded, only won over, so when she chooses to curl up next to you, it feels earned. She suits cosy slice of life, comedy and slow-burn romance. On Affiny, Catgirl (Nekomimi) is one of 15 anime species, and the most popular.
What "nekomimi" means
- Neko (猫) means cat.
- Mimi (耳) means ears.
So nekomimi is "cat ears", and by extension a character who has them. The same pattern gives you kitsunemimi (fox ears) and usagimimi (rabbit ears). The umbrella term for all of them is kemonomimi, "animal ears".
Where catgirls come from
Cats have a long history in Japanese folklore:
- Bakeneko (化け猫, "changed cat") are ordinary cats that become supernatural with age. They can walk on two legs, talk, shapeshift and even take human form.
- Nekomata are bakeneko whose tails have split in two. They're more powerful, and older stories made them dangerous.
- Maneki-neko, the beckoning cat statue with a raised paw, invites good luck and customers into shops.
- Ancient Egypt revered cats too, and the goddess Bastet was shown with a cat's head: one of the oldest cat-woman images in history.
In manga, cat-eared women appear from the 1970s onward, and the design became an anime staple in the 1990s and 2000s. Today catgirls show up in anime, games, VTubing, fashion (cat-ear headbands are everywhere) and, of course, AI companions.

Classic catgirl traits
- Playful and curious. Distracted by anything that moves
- Affectionate, on her terms. Clingy one minute, aloof the next
- Independent. Won't come just because you called
- Proud. Hates looking foolish, which makes it funnier when she does
- Verbal tics. Many end sentences with "nya", the Japanese sound for a meow
- Expressive ears and tail. Flattened ears when annoyed, a swishing tail when curious, a puffed-up tail when startled
Cat habits catgirls borrow
Writers love giving catgirls real cat behaviour:
- Napping in sunny spots, for hours
- Loving fish and hating baths
- Purring when happy, hissing when annoyed
- Knocking things off tables to get attention
- Curling up on your lap, then leaving the moment you get comfortable
- Bringing you "gifts"
- Kneading blankets before sleeping
- Being terrified of cucumbers (a famous internet joke)
The emotional core
A dog loves everyone. A cat chooses. That's the catgirl's pull. Her affection is selective, and a little possessive: once she's decided you're hers, she'll ignore everyone else to sit on your keyboard.
The best catgirl stories are about earning that trust. A stray who flinches at first. A proud café worker who pretends not to notice you. A familiar who insists the contract is the only reason she's here. The payoff is the first time she falls asleep next to you.
