This is exactly the kind of semi-ridiculous thing I like about home automations: the power to answer one's most trivial curiosities.
I'd probably add a logger, so I could follow the history of Mohkno's food thievery, then try different techniques to discourage her. Have ha also play a recording of you saying 'Mohkno, no!' Some activity to distract her during the critical food-stealing window. Or go all-in and get those microchip-reading pet feeders.
