DH and I have noticed a definite change of feline mood today. The overlords seem to have the hump. All we can think that we've done wrong is that we went on a day trip yesterday so they were at home alone between 9am and 9.30pm which they aren't especially used to as there's generally someone around. They were fed before we went and, granted we were a couple of hours late back for their tea but we always leave dry food out for them so they weren't exactly starving.
But they're definitely cheesed off with us. Is that possible?
