Need advice: I have 2 ferrets both are approx. 2 1/2 years old and I believe in excellent health. Both are always together but the little boy sometimes experiences difficulty breathing. He kinda gulps for air then pants 3 times. Last weekend it happened all night so the poor baby was exhausted by morning. I sat up with him. I tried giving him water, treats and ferritone. He took the treats and ferritone but nothing seemed to help. Nothing new around. And nothing he could get into. His sister never acts this way. I questioned the vet last time but she couldn't tell what was affecting him cause he wasn't doing it then. Thought maybe he is allergic to something but this happens at home and away from home. Is this a sign of something more serious than allergies? It happens maybe once a month if that. Should I be concerned? [Posted in FML issue 2377]
