They will need a bath occasionally, nail clipping frequently and brushing on a regular basis. Their ears and teeth need to be cleaned also on a regular basis. Ferrets do have a rather strong scent but ferrets are normally de-scented and neutered at a very young age before being sold. Even after de-scenting, there can still be a mild musky odor. They need a high quality ferret diet mix along with treats. They eat every few hours so fresh food must be available all of the time in a spill proof bowl. They love to knock over their food dishes. Ferrets need a complete diet with at least 36% protein, so read labels. As far as types of litter, pellets are the most highly recommended.
