Got a new hamster last week. Our 4th so not new to this. New big cage. Hamster seemed fine. Very alert and inquisitive. We haven't handled him yet as giving him time to adjust. Eating and drinking all fine. He is in a quiet warm room. Just gone to see him and noticed he is vey wet underneath. Obviously thinking wet tail. Could it be anything else? Have booked emergency vet appointment for the morning. Can I do anything in the meantime!
