<LOL> It sounds like you got it right the first time, though. Susan posted
a great description to take to that Brewer's yeast health food store.
A note on Brewer's yeast, though. Years ago I read that Brewer's yeast
changed the chemistry in an animal's body and essentially made him taste bad
I put a bowl of Brewer's yeast down beside my cats' food (I have 4 large,
gorgeous, sweet cats). For 15 (?) years now they've licked at it and eaten
it as though it were just another little bit of food.
I've not had a flea in all that time. So if it doesn't work, my
bug-repelling mental powers are stronger than I thought!
