Two friends Sandy, yawning and Skippy. Intact Hobs  ( males with testicles) should be housed separately, although they can be exercised together under supervision, but there is the possible risk of fighting.
 Jill's (Females) can be kept together, or with castrated males without problem.
Sandy exhibits the formidable teeth possessed by ferrets, they are capable of inflicting nasty wounds, although a well treated ferret will not bite.
Note: it is not wise to put any type of pet animal near to your eyes, you could be badly injured as a consequence.
