You shouldn't feel caged by labels. They should be a waymark, something to guide you in the direction you wanna go. You can call yourself a cladotherian, even if your "clade" is crocodiles and lizards. You can call yourself objectkin for identifying as an animal. You can avoid all fiction-related labels, even if most people only know your kind from fiction. You can call yourself nonhuman, even if your kintype is per definition human. You can do whatever you want
