If he clears up completely today or tomorrow it could be due to the horrid amounts of cigarette smoke which can come into our condo when the most recent neighbor downstairs (who now smokes outside sometimes if the weather allows, lowering the burden) stops smoking outside due to heat or cold. The smoke levels that travel along pipes and sometimes vetnts gets dramatically worse when her smoking daughter or her smoking ex-husband, or both visit -- and I think both visited yesterday night and overnight because I got nailed badly myself starting a few hours after coming home. It's known that ferrets have an assortment of problems with tobacco smoke (which is why they are used a research model animal for the harm that tobacco smoke causes). Whether asthma is among those things I don't know and my eyes are not up to checking abstracts today but it's certainly something I could suspect is possible. He has had allergy problems this time of year before in our location before now, though.
