The ears move before she answers. She has not decided what to say yet and they have already given it away, and now she knows you saw. That involuntary tell is the whole reason catgirl roleplay chat works in text: it hands a writer a second channel running underneath the dialogue, saying the thing the character is trying not to. Free, anonymous, nickname only.
Nekomimi, and the wider family
Kemonomimi is the umbrella term: human-shaped characters with animal ears and usually a tail, and nothing else changed. Nekomimi is the cat branch of it and by far the biggest, but the room runs foxgirls, bunnygirls, wolfgirls and the occasional otter, and the vocabulary is shared across all of them. Catboys are played constantly and are chronically under-pitched, which means if you want one you will get one.
The design is deliberately minimal. Two features on an otherwise human character, which is exactly why it is so flexible. You can drop a catgirl into an office, a bar, a fantasy tavern or a shared flat without rebuilding the world around her. That portability is most of why the archetype has lasted as long as it has.
Three things it is not
Worth being precise, because these get muddled and people end up pitching in the wrong room.
It is not furry. Furry chat is built on anthro characters and a fursona, a species identity a person actually claims as their own, with a fandom and its own art culture around it. A catgirl is a character design, not a sona, and the body stays human.
It is not pet play. In kitten play the person is human and putting on a role, with gear, a collar, an Owner and a real power exchange underneath. Here the ears grow out of her head and the scene is usually a story rather than a dynamic. The two do cross over, often, and a scene can absolutely be both. Just say which one you are pitching.
And it is not monster girl roleplay, where the anatomy actually changes and the species drives the plot. Kemonomimi keeps the body and takes the mannerisms.
The pet-or-person question
This is the fault line the genre runs along, and pitching without answering it is the most common reason a catgirl request gets ignored.
One end plays her as fully a person who happens to have ears: a colleague, a girlfriend, a mercenary, someone with a job and opinions, where the cat traits are texture and running jokes rather than status. The other end plays the traits as most of the character: purring, kneading, sleeping in sunlight, a vocabulary that thins out when she is happy, an owner rather than a partner. Both are common. They are not the same scene and the two crowds want quite different things.
Most writers sit somewhere in the middle and it moves during a long scene, which is itself a good plot. Say roughly where you want to start. "Person with ears, no owner dynamic" and "want to be kept" are both perfectly reasonable openers and both get taken.
What actually gets written
- Headpats and ear contact. The signature move of the genre and the one that carries the most weight. Ears are sensitive, ears are personal, touching them without asking is a whole beat. Writers build entire scenes off the first one.
- Purring as a tell. Involuntary, embarrassing, impossible to deny. The single most useful device the archetype gives you.
- The tail. Mood, balance, jealousy, and the thing she keeps wrapping around your wrist without meaning to.
- Territory and jealousy. Scent, sitting on your things, an unmistakable opinion about anyone else in the room.
- The maid crossover. Uniform plus ears is a durable pairing and overlaps with uniform roleplay and cosplay chat.
- Domestic slice-of-life. Living together, and a partner who is enormously affectionate on her own schedule and unreachable on yours. Runs long and runs well.
Playing one that reads well
The failure mode is writing a person who says "nya" occasionally. That is a costume, not a character. What lands is behaviour: the pause before she accepts affection, the deliberate slow blink, deciding she is done with the conversation and simply leaving, coming back forty minutes later as though nothing happened. Cat logic applied to an adult woman with a full inner life is funny and disarming at once, and it is what your partner is actually there for.
Verbal tics work best used sparingly. One well-placed sound beats a paragraph of them. And resist making her compliant. The archetype has bite in it, which is why it holds interest past the first night.
Everyone written here is an adult, and the ears do not change that. The rules are the same as anywhere else on the service, limits get named before a scene rather than during it, and a quick out-of-character check mid-scene is normal.
Finding a partner
Pitch with the species, the side you want, the register, and post length. "Catgirl flatmate, slow burn, domestic, para posts" is answerable. Add whether you want the pet dynamic or not and you have cut the guesswork out entirely. The roleplay glossary explains the shorthand, how to roleplay covers post length and pacing, and finding roleplay partners covers what makes a pitch get answered.

The room is open
Ears, tail, and an opinion about where she is going to sit. Someone in there is waiting for exactly that.
