I was doing some research about crystal litter. my cat has pododermatitis(pillow foot) and found that since silica dust is extremely drying, (which is obviously why it works really well) it exacerbated her condition. I didn't even think about it being a problem until it turned into one. So it's not the right choice for cats with sensitive feet or allergies apparently. Also I read somewhere that silica dust is considered a human carcinogen, does anyone know if this is true? Has anyone had any bad experiences with crystal litter?
