Most ferrets utilised for laboratory studies are males due to oestrous related health problems associated with females. Female ferrets are induced ovulators and can develop severe hyperoestrous if not mated. Laboratory ferrets are often purchased pre-castrated and 'de-scented' (i.e. anal gland sacculectomy).

Due to the small number of laboratory ferrets compared to species such as mice, there are no specific strains/stocks commonly used. Researchers often request natural wild-type colour patterns (called sable or fitch) which is often in contrast with the various coat colour variations found in domestic populations. Some studies have also utilised albino ferrets.
