Perhaps so. At least I can say that Ditto and Kova won't mind that sort of thing too much.

[ Ditto flat out wouldn't mind due to his nature as a familiar, and Kova had more time to adjust to unusual scents on people and what was expected of him here. ]

Rio and Harmony might be less familiar, but they seem to adapt well.

[ Being more... ordinary kitties, but friendly enough to adjust to cafe lifestyle. ]
