I also started using the woody pets litter from TSC. My fuzzies love it and so do I. Really good on odor control. It does cost a little more. I paid $3.98 for 40 pounds. I do think it lasts longer. My babies are not sneezing as much which makes me wonder about probable chemicals in the wood pellets. It is called a fuel. Just my 2 cents. Linda [Posted in FML issue 3760]
