So I was talking about some of the plants and references to smoking with a friend of mine when she mentioned the catnip item. Then I remembered this item exists and I noticed a plot hole! Or maybe it was intentionally left there by SE!

Item description for Gaelcatnip:

"A relative to pepper- and spearmint, gaelicatnip is an aromatic herb often brewed into teas. While it has no effect on the five races, the oil contained in the leaves is known to cause gaelicats and other normally aggressive feline beastkin to exhibit excessively playful behavior."

So it has no effect on the five races... Hyur, Au Ra, Elezen, Roe, and Lalafell. Ergo it must have an effect on Miqote also! Considering this item was released in Heavensward when a sixth race came out, clearly they were referring to the non-feline races in the game.

Miqote = Beastkin confirmed!

Or maybe it's just a plothole and someone forgot about the Au Ra when making the item description.
