You can also use the stuff sold on large mesh bags to "deodorize" rooms/houses with animals - a former GF had 2 cats, one who would spray EVERYTHING in sight. When we first met, she was living in one of those "Cardinal Communities". If you're not familiar, here in the East, they pour a big slab, then a truck brings in 8 apts. in 4 sections. Hoist them onto the slab, put down the roof, and that's it. Cheap construction.Do they sell large Silica Gel packs? I can't find them anywhere and the incompetant people I ask at the stores near me think i'm a looooony.
