Hi Y'all, Marilyn here, and I also have forced hot air, and heat vents. I did get deflectors, and thank heavens they are making them a little sturdier than they were, and they work pretty well. When the heat or cold air is on, they blow the heat in one direction. They are close to the floor, this years model has better magnets, and only cost about 6 dollars each. I would suggest you buy one or two, depending on how many heat vents you have in the one room where the accidents happen most often. Mine don't mind peeing in the vents, BUT they do not like the top of the deflector pushing their fur the wrong way. If they scruntch down, they pee on themselves, as these deflectors are close to the floor. If all else fails, the deflectors wash easy. Marilyn at Ledoux Hospice. [Posted in FML 5586]
