Hi, I recently saw on a news program that if your cat poops in the house, and sits there awhile, and you breath it, then it can somehow cause a brain tumor in humans. Well, they researced it, and found that it is possible that it is true. Also, they said little boxes, are not good. So it brought up a question. What about ferret poop? it sits in a litter box, you smell it, can it cause a brain tumor in humans? If anyone knows any info about this, or has heard the same thing, let me know. Thanks Mandy & ferret (cant think of a name yet) maybe Abbey. [Posted in FML issue 1870]
