Cat Cage Hammock Size: Approximately 44cm x 53cm String: 9-16cm, adjustable Clip opening: 6mm I received this as a gift, but it couldn't be attached to the top of my cage because the 6mm clips wouldn't fit. Instead, it ended up on the second shelf, so I couldn't use it as a hammock and have been storing it. Please consider this item with the understanding that it has been stored at home. There are no tags, so the material and manufacturer are unknown. The fabric is thin.
