Thank you for viewing. I have updated my profile, so please be sure to read it. m(__)m This is an outdoor hammock that can be secured to a carrier. It comes with a total of 8 strings, 2 on each side, so it can be securely attached to the carrier. It has a pocket, so your ferret can sleep soundly. The inside is fleece (with anti-pilling treatment) on the top and bottom, so it's warm. The back of the hammock is 13oz washed denim, making it durable. It can also be used for small animals other than ferrets. Hammock size Approximately 30cm (height) x 30cm (width) (±5mm) String length approximately 30cm (±5mm) Carrier size in image External dimensions approximately 33cm (width) x 51cm (depth) x 30cm (height) ☆The carrier in the image is unused. ☆Due to the thickness of this product, it cannot be combined with other items.
