This post is in answer to Vicky Kuruc's question about the safety of All Pet Pine litter when used for ferrets. I just read the information on the package of this litter which I have used successfully for my ferrets for two years now. The info states that this litter has been processed to eliminate all respiratory dangers to small pets and will not have an adverse affect on the liver and other organs. None of my furkids have ever had any sort of reaction to this litter. They are all healthy, active and keep me on my toes each and every day. As a side note, this product is made in Canada. I am not familiar with the pine cat litter. I hope this helps you. Cordially, Greta Hoisington [Posted in FML issue 4335]
