Cleaning products that are toxic for your kitty are probably also toxic for you as well. Switching to products from Dr. Bronner's, 7th Generation, and BioKleen, or making your own with white vinegar and baking soda have the added advantage of being cruelty-free (not tested on animals like Clorox, Proctor & Gamble, and SC Johnson products all are). Instead of chemical "air fresheners," try using zeolite crystals near the litter box. These can be "recharged" by setting them outside in the sun on bright days and rinsed off if they get dusty. I also like cotton balls soaked in essential oils such as peppermint or lavender tucked into a tall jar or placed out of an area kitty can reach. This is a great "emergency" fix when I've had to transport Tom cats in my car to be neutered!
