Hi! I have a 1year and a half Russian dwarf hamster. When I'm at uni he has two big cages, and when I go home he has one big one and never used to mind. This time he seems manic, and doesnt get excited for his food like he used to, hes started biting as well. He gets time out his cage every evening and I cant think of anything I've done differently this time ive been home! For extra info he had some kind of abcess on his chest which was treated with antibiotics and metacam syrup.
