Hi, You'll most likely see me asking the same confused question on the FAIML list, but what the hey. 8) I went to the homepage of Timmy's Tonic and began to read about it, but gave up when I read one of the tonic's is clover honey based. I wanted to get it to use with my babies, but one of them has Insulinoma. But then, I got my copy of today's FAIML and read there that someone with such ferret IS using it. So I posted there. Then I got this issue, and saw it again. *groan* Sorry. 8) But anyhow, how can you use it on a Insulinoma ferret without a reaction if it does have the honey in it? And without regular glucose testing, how DO you know it isn't causing an adverse reaction? Second question: In one recipe for Duck Soup, it called for brewers yeast. I don't use Totally Ferret, I use Iams which already has yeast in it. Do I need to add more? What exactly does the yeast do, and what have studies said about how much is too much or just right? Thanks a lot, sorry about the multiples. Julie [Posted in FML issue 2419]
