Acting Town Leader!
Leader of Billie's Daring Escapades (a not so secret society for adventuring not-cats of all persuasions)!
Additionally, alongside running their Adventurer's Society and acting as leader of the entire town, Billie somehow also finds time to raise a veritable menagerie of anger-prone not-kittens named after birds... so they're.... angry not-bird not-kittens!
*Creatrix sent Billie its first ever handmade chicken plushie on Thursday, September 1st, 2022*
From artist (link attached to image):
"since you didn't specify anything for the body plan i took some liberty and made a noodle dragon since i hadn't done one here yet.
hope i didn't make them look too mean! referenced One ferret and took a little inspiration from the mononoke wolves."
Literally the only time Billie ever stops glaring is when they'e all alone with their birbs (both their not-cat not-birbs and just plain old regular birbs... Billie's not truly able to tell the difference)
(English name that means determination and strength - pretty good descriptors of Billie)
Billie's kept not-birb not-kittens: Merula (protective), Birb #1, Shrike (protective), Birb #2 (mysterious), and Birb #3 (protective), Black Birb (protective)
Not-kittens that grew up and left the clan: Katja (2737; jovial), Kotori (2938; ordinary), Dove (129841; jovial), Oriole (178562; gentle), Thrasher (192855; ordinary), Cuckoo (304928; ordinary), and Nuthatch (255227; imaginative).
At time that Katja left, jovial wouldn't have matched very many others in the village. And Kotori had ordinary personality so wanted ordinary life.
