1 Another Revolution question: How long after administering Revolution can you wash your animal? (I read on the Revolution site that the Rx goes into the bloodstream from the skin, so it must be ok to wash after a while.) 2 I've been using Solid Gold bone meal as a supplement to my ferrets' soup, and now can't get it through Amazon and most other sites say they don't have it any longer. Have you heard of any problems with the meal itself? I haven't find anything critical on the net, so assume that's not the problem. Got any other brands to recommend? Amazon does have Kal and Now brands, but neither claim, as does Solid Gold, that there are no heavy metals in it. (I haven't found anything from Kal about being free of heavy metals and Now says "Our sterilized and sanitary NOW® Bone Meal Powder is tested for heavy metals such as lead and aluminum to assure the lowest levels possible.") btw, Grinding bones isn't practical for me [A later P.S.]: I got my answer to the Revolution question that I asked in my last post. (It's ok to wash after 2 hrs). [Posted in FML 7303]
