Yuki, Ooops forgot to answer that one, or try to.  that is a good one for Dr.
Williams.  I have four cats and have never had a problem, so I think it
might not harm cats, but I would love to hear what someone else thinks.  I
gave the cats Colloidal Silver also during the out break here so that might
have helped, it sure saved ll the ferrets.  Stephanie
