Hello! My pet store told me that I could use Yesterday's News cat litter instead of their ferret litter. They said that the ferret & cat litters from Yesterday's News are the same & that the cat version is cheaper & is not harmful for ferrets. Has anyone heard of this before? Does anyone use the Yesterday's News cat litter for ferrets? Thanks! Jessica, Maggie & Milly [Posted in FML issue 4614]
