Hamsters on the loose can eat holes in carpets..even in the centre of the rug….as my godmother found out so many decades ago. Lol Michael should be the one…the only one…looking after this pet. In fact, I’d make him take it back to the school as he didn’t ask his parents for permission, first , to bring it home. His mom is working and anything could go wrong while she’s not home. Turn the car around, Ellie.
