They just go by "Cat".

This lovely little critter has taken an interesting path, from a yinglet fursona that accidentally became sentient, to this yinglet-adjacent Thing that's something like 50% silverfish and 50% a mishmash of nonspecific mammal traits... It's always fun, the way us Woods tend to slowly "grow" a more specific and aesthetically-developed form the more we discover about our tastes and personalities.
...She still has the yinglet accent, of course. It kinda morphed into a French one though??
