So.. last night a friend came over, and as soon as he came in he told us our house smelled like fog machine (which has a distinct smell, different from just burning wood or matches or cigarettes). We couldn't smell it last night, but just got up this morning and walk into the kitchen/livingroom area and yeah.. it smells like fog machine. My bird has been covered up in his cage all night in the livingroom and doesn't appear to be ill from whatever it is. It is very very faint, but it is there. No appliances are left on, no haziness in the rooms, just a slightly noticeable smell of fog machine.

Any ideas on what this might be? Anything I should be concerned about? Who should I give a call if it gets worse and needs to be checked out? Not incredibly concerned, as I said it's been present since at least last night and if it were harmful, I'd likely see something with the animals, but... don't want it to get worse, and no idea what could be causing it.
