You might want to be careful with the cat vitamins. Ferrets have an unusual metabolism and while it may do no harm, on the other hand it may. Here is some information I hope will be of some help. Probably the most common vitamin supplement in the US is FerretVite. I will list the ingredients and the nutritional breakdown. Then you can look for those things in cat or other pet supplements. I will not list the ingredients like water and corn syrup, since the one is obvious and the other probably does the ferrets no good. Lecithin, Molasses, Taurine, Ascorbic Acid, d-Alpha Tocopherol Acetate (vitamin E), Cod Liver Oil, Sorbic Acid and Potassium Sorbate (preservatives), Ferrous Gluconate, Magnesium Sulfate, d-Calcium Pantothenate, Thiamine Hydrochloride, Niacinamide, Pyridoxine Hydrochloride, Vitamin A Palmitate, Potassium Iodide (presumably a source of trace iodine) Riboflavin, Folic Acid, Vitamin D3, Vitmin B12. Vitamin / Mineral breakdown per teaspoon (~ 5 ml): {Moderator: the following table is in a monospace font for alignment} [The FML *is* edited using a monospace font but most e-mail readers have their own ideas about how to display things ;-) BIG] Magnesium 0.007% Iron 0.009% Manganese 0.018% Iodine 0.003% Vitamin A 359 IU Vitamin D 27 IU Vitamin E 3 IU Thiamine 2mg Riboflavin 0.2mg Pantothenic Acid 2mg Niacin 20mg Vitamin B6 1mg Folic Acid 0.2mg Vitamin B12 0.000002mg Taurine 42mg Ascorbic Acid 10mg (vitamin C) Wow. I was aware that ferrets needed taurine, but the amount in the supplement surprised me! Directions that come with this product: During convalescence: 1/2 teaspoon (~ 2.5 ml) daily per pound (~ 0.45 kg) of body weight. When pet is not eating and product is used as a main source of nutrition: 1 teaspoon (~ 5 ml) daily per pound of body weight. For active ferrets: 0.25 teaspoon (~ 1.25 ml) daily per pound of body weight. It may take some calculation, but from that you should be able to get a good idea of a healthy daily supplement for an average ferret. LATER NOTE: I did leave out some things from the beginning of the ingredients list: Malt Syrup, Corn Oil, Maltodextrin. I had assumed that those were just for a sweet taste but it appears that they were deliberately added for their calorie and fat content, for use with ferrets who may be off their feed. That does make some sense, but I am averse to feeding sugar to healthy ferrets on a regular basis. They do need fat too, but I question whether corn oil fills that role well.
