Considering the little girl brought it in, it’s definitely more plausible she wouldn’t notice the magnet. And considering the amount of parents who give hamsters as pets and never take any responsibility over it themselves, even more so.
But I’d also assume, with no real insight into the behavior of hamsters, that one in this situation would wind up either tearing it’s cheek off (depending on the strength of the magnet) or figuring out it can dislodge / move enough to free it.
Ditto. API thing was transition as well
