Possibly your kittens do not know that cats don't eat cinnamon or honey. Or maybe they do not know they are cats?

I believe they know they are cats, because we tell them frequently—and they behave in all ways like cats, including the pursuit of inconvenience—but I also believe they are open-minded toward food, as in, they can see no reason not to be eating anything except mysteriously we won't let them. We are trying to delay the onset of mooching, but it's a temporary solution at best.
