Gizmo, however, didn't hide at all.
He just waltzed in, ate the food we put out for him, ate Linney's food for good measure, had a dump in the litter tray, then upended it so all the litter and poo scattered on the carpet.
Nothing loath, he then went to sleep in his cat bed (which his previous owner had supplied).
His next move was to try to take Linney's house from him, but Linney had other ideas..........luckily.
So rescue cats do vary enormously.
