Ferrets
Ferrets were originally domesticated from the European polecat. It isn't clear exactly when this took place, but it was somewhere around 2500 years ago. Originally they were used to hunt rabbits, and rodents. Hunters would send the ferret into a rabbit burrow. The ferret would chase the rabbits out of the burrow where the hunters waited to shoot them.
Diet
Unlike other small mammals kept as pets, Ferrets are carnivores. In the wild they eat rabbits, mice, rats and other small mammals they will also eat bugs when need veternarian. Domestic Ferrets biology is no different than their wild cousins.
They require a diet that is a minimum of 30% protein and 18% fat. Meat based protein is preferable to vegetable based because the Ferrets utilize meat based protein better.
Food should be available at all times since ferrets eat on and off all day and all night.
Fresh water should always be available at all times
Housing
Ferrets are best kept in cages. There are a number of ferret cages on the market, or a small dog crate only if being left for a short period of time with narrowly spaced wires can be used. Ferrets are escape artists so make sure that the cage is sound and well constructed. Many of the specialty cages for Ferrets have a second and third stories. The larger the cage the happier the ferret. You can connect several cages together with special tubing found in many retail and pet stores. Ferrets like a nice soft comfy place to sleep. You can make a hammock or purchase one especially for ferrets. Provide several comfy places for them to sleep and cuddle up. Make sure there is a hiding place for the ferret, this can be any type of plastic hut or ferret tent, etc.
Place a litter box in one corner of the cage for potty training.
