My good friend is coming to visit for Christmas. The problem is that she's allergic to cats! I'm going to keep our kitty quarantined in the mudroom while she's here, and I'm going to do a thorough cleaning, vacuum with a new bag, change the furnace filter, dust, etc. I was wondering if there were certain oils, herbs, or incense I could use that might help keep her from feeling lousy just in case I miss some kitty dust?
Probably none until you find out if she has other allergies as well. I have heard that burning a salt candle or lamp can purify the air although I have never tried it.
