Two questions about litter: Are there any problems withthe litters that say they reduce smell? I.e., anything suspect about the deodorizing material? I am now using a Healthy Pet cat litter called Dust-Free Fiber They describe ot as Pure cellulose fortified with something that blocks amonia formation.. It works great, but is costly. What do you recommend for economical litter that doesn't track and keeps smells down? RiccoRobertAdaTinaArtie [Posted in FML issue 4888]
