Cats are creatures of habit, so she is probably confused and stressed that you were away, and now her daddy is away. Ours do that if Shane or I are away for more than a day, and take a few days of regular routine to feel settled again. When is your hubby back? She may behave strangely until after he returns.

We just had the in-laws invade our house over Easter, and one of the cats was leaving a poo on the laundry floor each morning as a little warning sign to us that he/she was stressed - they show their confusion in various ways! I still don't know who it was, but it has stopped now that the house is back to normal.
