DD has collected gorgeous golden oldie cat from foster carer he'd been with for 2 -3 weeks and when home he rushed under the sofa bed in living room and hasn't come out (as far as she can tell) for almost 24 hours.
She has left his food, water, bed, blanket etc in the room with him. How long can she expect him to stay under the sofa? Should she be worried? Thanks for any advice!
