I just want to add to what Rochelle Newman said about dog food - she's right that there is not enough nutrition in dog food for ferrets - while there is nothing in dog food that is really harmful to ferrets, eating a complete diet of dog food will eventually kill a ferret - this is from Dr Judi Bell - Marshall Farms. Something is missing in dog food that ferrets need - and a straight diet of dog food can cause health problems in a relatively short period of time. The essential ingredients are present in cat food however, so that's no problem. I'm sorry that I don't know right now what those ingredients are, but ferrets should not be fed dog food on a regular basis. Now, eating a kibble here and there is not going to be harmful - my own ferrets steal pieces of food from the dogs while they are eating (I have such good dogs - they don't snap at the ferrets when they do this!) But eating a couple of kibbles a day is not the same as a complete diet of dog food, so please be aware. Debbie Riccio WNYFLFA Rochester, NY [Posted in FML issue 1240]
