@brdwybaby It just might be that the fragrances in the cat litterwere the cause of your sore throat. I have cats and only use unscented products at home because chemicals trigger my asthma and allergies. Cats don't like fragrances either and are more sensitive to it that we humans are. I use the recycled paper pellets cat litter because they are relatively dust free (Brands- Yesteday's News or Fresh News). I have lots of allergies to dust, molds, etc, and that can cause a sore throat for me. My airways will swell with fragrances triggering asthma and that makes it hard for me to be around people who are wearing them or places like the laundry detergent aisle in the grocery store. I also use HEPA filters in my home and do allergy shots. It's detective work to figure this stuff out sometimes.
