My ten year old has a friend who seems nice and has sane sensible normal parents and yet she wears a tail and tells my daughter she’s a therian. I’m not in any way happy with all the furry rubbish and this feels along the same lines. My daughter has now asked to be a cat for Halloween, then asked for a furry tail as part of her costume, and now I think it’s actually so she can join in with her friend. They are only ten so it’s likely just play but there’s no way I’m letting her go out in a tail 🙄.
