Rats wanted for next weekend

jfs is clearing out his basement this weekend in preparation for several people to sleep down there next weekend for his birthday. He was mentioning on the train this morning, that it could do with a bit more atmosphere for the period after midnight when he shuts the door at the top of the stairs, locks it on the outside and turns the lights out. As several people have rats and other small squeaky rodent friends, would any of them like a short sociable city break in Ilford?
