My husband goes away quite a lot and he left on Thursday for a month. I think Zimba is really missing him. He keeps sneaking upstairs and looking in the bedroom and ensuite, I think he's looking for him. He seems a bit unsettled, not really naughty but a bit like he doesn't know what to do with himself. Is there anything I can do to help? Would a piece of husband's clothes in his bed help do you think?
