Yes, could be that Ally is confused 'cause you've been away first and now your hubby. Some cats react that strongly to changes in their daily routine. She might be upset 'cause she feels being left alone... or something else has shocked her, who knows...

But I would also recommend to have her checked by a vet, 'cause a change in behavior could also be an indication for health problems, even though I think Ally is "only" offended.
