Mary just ran upstairs meowing her head off. Dunno what happened, as she'd been sleeping peacefully behind the couch when I came up, and I don't think Pi could fit back there to bug her. Anyway, she stopped meowing after I picked her up. After about a minute, Wilma comes up meowing her head off. They're now sitting on a chair cleaning each other. BTW, you can find more pics of them here .
