To select the right size cage for a ferret, you should consider getting a cage that is at least 24 inches wide, 24 inches deep, and 18 inches high. This will provide enough space for your ferret to move around, play, and have separate areas for sleeping, eating, and using the litter box. Additionally, make sure the cage has multiple levels or platforms to allow for climbing and exercise. It's essential to provide enough space for your ferret to stay active and healthy.
