We have cats that have been urinating in our floor vents and we found out tonight when we turned the heat on for the first time since last winter. The odor is unbearable! We went out and bought all new diffusers for all floor vents and got an activated charcoal filter for the heat pump return. Can anyone recommend something that can be done at the floor vents in the meantime while we try to get a duct cleaning company to the house?

What does it smell like?
Every winter I notice a stale, sickly sweet smell emanating from the air vents. Sometimes it's there, sometimes it's not. It seems to depend on the changing air pressure differences between the rooms and the air ducts. During the summer I don't smell anything. The previous owners of the home did not tell me about this, and they had pets (including a cat). I wonder if I have the same problem.
