Hi, Gracie! Hopefully, Gary will jump in here and give you a more complete explanation of Timmy's Tonic. Basically, though, it's an herbal remedy (which also includes colloidal silver and some other components) used to help ailing ferrets. Gary designed it to feed his ferret Timmy, who had terminal lymphoma. Timmy defied all of the doctor's expectations and lived for several more years past the life expectancy which the vets' had given him, and (from what I recall) just passed away a few months ago. Gary sells the Timmy's Tonic now himself, and many shelters and individuals use it on their ailing ferrets. - Ela Ela Heyn Harborside Mail Stop 3024 201-860-3336 [log in to unmask] [Posted in FML issue 2785]
