I posted some info about Linatone/Ferretone dosages in a fairly recent issue of the FML (don't remember the issue #), but here it is again. This is a quote from Lenny Southam, DVM, who is the veterinary manager of the CompuServe Pets/Animals Forum. It came up in an online ferret conference we did there last year. "[I] can't find toxic levels of A in ferrets. 500U/day is used in mink for correction of deficiencies and it's prolly similar in ferrets. i'd be conservative about its use as a treat in ferrets to stay on the safe side. you can produce toxicity in cats at about 1000 times recommended doses or 20000-40000 ug/kg/day over several months to years. And for Troy... toxic dose in rabbits is about 190,000 U/KG sorry for it all at once and there isn't much info...that's what you get with tapcis. ann said that linatone has 1500U/teaspoon so normal daily requirement in mink is 1/3 teaspoon. would take more than that to be toxic." Michelle, I would say 4 squirts of Ferretone a day, even diluted, is more than they really need. IMO, Ferretone should be used as a treat and as a training aid. If your ferrets are getting a good quality dry cat or kitten food, the vitamins in Ferretone are not necessary. --------------------- Katie Fritz CompuServe Small Mammals Section (S11) Co-Leader, Pets/Animals Forum Internet: [log in to unmask] CompuServe: 71257,3153 [Posted in FML issue 0751]
