However by lower price I am not referring to the generic brand at the grocery store. Most of the grocery store brands are good for cats but not so good for ferret since they are at the low end of the cats nutritional needs. Although these are all pricey and hard to find. By feeding your ferret a high quality diet that meets his proper requirement you will find yourself needing to change his litter box less frequently as there will be less volume. Fresh clean water should always be available for the ferret.
Ferrets can very quickly suffer from dehydration.
If your ferret is ill your vet may recommend you supplement his diet with vitamins but stick with the quantity the vet recommends as large quantities of vitamins over a long period of time can build up in the body and cause problems themselves. During the colder months when you run your heat the air in your house may become dry. This dry air can cause a ferrets skin and coat to become dry itself. A few drops of Ferretone or Linatone a couple times a week can help maintain a healthy coat. I mix equal parts of olive oil with the Ferretone to cut down on high vitamin A content.
