For about the past 4 days, my 2 yr old male hasn't acted like he feels well. He sounds like he is having trouble breathing. He sounds like he has some congestion in his lungs and sometimes starts breathing really fasts like he is struggling for air. He seems to be eating but maybe not as much as before. He has also become very lethargic (he has always been extremely lazy and somewhat overweight). I know that ferrets can get colds but I'm not sure if that is what is wrong with Cassidy or if it is something more serious. If you have any idea what could be wrong, please respond asap. I will probably take him to the vet in the morning. Thanks, Melanie [Posted in FML issue 2044]
