my pets have left stains on my hardwood floors, but i think i'd rather carpet than refinish. i already have a level differential between the living room and kitchen floors, as the living room was carpeted long ago. the doors are also shorter than the norm, to have made clearance for the carpet. can i have new padding and carpeting laid down and have the smell be gone? or do my floors need special treatment and/or deoderizing first? i really can stand the smell in the humid weather! please help!
