I like to warn all of you against litter pearls made of silicum like: Cat Clitter etc. You are not allowed to use this kind of litter for ferrets nor for kittens. Because these pearls are dangerous! There absorption is so high that if it's been eating (by accident), is sticking on the eye etc. your beloved pet will be in danger! Please don't use that stuff! Over here (Holland) we already been warned against it! Regards, Carmen Ferret's Friend Forever Postbox 12 NL - 2024 ZG Eck en Wiel [Posted in FML issue 3299]
