I move the magnets down specifically for these photos, but the rest of the time even when she's hooked on the fridge, she can't reach them (and doesn't try if they're too high up).

Even when they are in her reach, she usually can't stay up long enough to get them down (for example, she's aiming for the yellow/orange in those photos, and she was completely unsuccessful; they've been moved since).

So far, she's shown no sign of wanting to eat or chew on the magnet (she wants the rubber silicone instead, which is about just as uncool).

But yeah, I take your point. :)
