Question......

Re pennyroyal- I've read in several books , by vets, that this is used. Do you have any site that indicates otherwise? I've only recommended it once-here- I won't again if what you say is the case but would like to have that info documented. An Alternative is to give brewer's yeast ( powder or tablets) not only in the diet but rub the powder into the fur. This would have to be repeated as it wears off. If licked off it will only provide some healthy B vitamins.
