SANKO Ferret Cage (82 x 51 x 52.5 cm) - Brand: SANKO - Type: Cage - Color: Black - Material: Plastic/Metal - Size: Medium Thank you for looking. I used this for just under 2 years and then stored it. I am selling it because I am moving. It can likely be used for small animals other than ferrets. I no longer have the instruction manual, but assembly is simple.
