I have 3 cats and 3 ferrets, all of which use clumping cat litter. I am well aware that this is not the best choice of litter for ferrets so please do not flame me regarding that. My question is--has anyone ever heard of using lime in their litter boxes???? I am told it works amazingly for odors in zoos. I want to know if it is safe for our domestic fuzzies. Thanks in advance for any information regarding this product. Renessa [Posted in FML 5994]
