A few drops a week is a good amount. Small pieces of banana or one or two raisins may also be used as treats. Ferrets should always have access to clean water. This can be supplied in a bowl or from a water bottle such as those used for guinea pigs and rabbits. Housing Ferrets are clean animals, and if given proper housing, will not soil their bedding or food.
Ferrets tend to urinate and defecate within a few minutes after waking up.
They also usually back into a corner to have a bowel movement. Please keep the litter clean or your ferret may defecate near it, instead of in it. Ferrets do best when housed in a cage large enough to let them run around. Small wire cages or aquariums may be used, but it then become vital to allow the ferrets at least two hours a day outside the cage for exercise. This time is best divided into two or three play times, and presents a good opportunity for you and your pet to play together.
