I noticed that somebody has been adding the tag non-mammal_breasts to wickerbeast posts: non-mammal_breasts wickerbeast
The wiki page says "Humanoid breasts on any non-mammalian species that does not, in real life, produce milk." (emphasis mine)
Wickerbeasts are a made-up fictional species, so they don't fit into the real life tree of life. They're not mammals, but maybe they could be considered mammals, so I don't know if non-mammal_breasts is applicable here.
Avalis are avian so non-mammal_breasts on avalis with breasts makes more sense there, but wickerbeasts are less clear. I figured I'd open this forum thread to ask.
