Since it is unlikely to find much Ferretone in California use the nearly identical Linatone made for dogs and cats. These are completely interchangable. I believe the main difference is the amount of vitamin A which is insignificant if proper kibble food is used such as Iams or Pro-Plan cat or kitten. We use the Linatone mostly to get the larger bottle size. We've heard that the increased vitamin A in Ferretone might not be good but I have no evidence that this is the case so can't recommend or not recommend either based on this. Congratulations to the CDFA and all of its allies in this effort. We were quite happy to read this latest report. Thank you on behalf of ferret folks everywhere. bill and diane killian zen and the art of ferrets [Posted in FML issue 1369]
