The answer for this amusing (or is it annoying for you?) behaviour depends on where she likes to spend her time when you aren’t at home. If she hangs out in the kitchen with her stash, then she is keeping you close by. If she drags your clothing into the kitchen away from where she sleeps, well….she wants the bedroom to herself. Regardless, she is identifying you as a really precious resource (affection, food, attention, all around personal servant).
