For multiple ferrets or if playtime is limited, a larger cage is better. Spacing on the bars must be such that the ferret can't escape. A blanket or towel will serve as a comfortable place for your ferret to curl up and sleep while a litter pan placed in one corner will serve as a relief area. The cage may be kept indoors or outdoors. If kept outside, shade should be provided to avoid heat exhaustion.
Supplemental heat is needed if temperatures fall below the freezing point.
Inside the house ferrets should be caged when not directly supervised. Eliminate loose boards, open drains or air ducts or other holes that ferrets will investigate. Exercise and Play Ferrets will jump, run around, slide, do somersaults and play games. They are very curious and like to investigate just about everything. The best toys for ferrets are those made of hard plastic.
