Hi. I've just been reading some of the scary stuff about the potential harm of wood smoke. We've got a Vermont Castings Defiant that has a catalytic combustor, so I know that helps. We live on high ground, not in a valley, which is good. I'm wondering if there's any rule of thumb, like if you come in from outside smelling of smoke you've just been breathing too much of it, or anything like that. Also, just last year I fenced in an acre in back of the house for the cats so they wouldn't get run over on the road and now I wonder if I'm giving them lung cancer being trapped next to the house when they go out. I'm hoping the scary articles I found on the net were intended for folks in areas at higher risk for pollution and I'm outside the city in KY. I hope somebody can tell me things are OK here. Thanks.
