The JR Farm Kapok Pod contains soft nesting material made from natural plant down for making their own nests, just like in the wild. Kapok is made using cotton wool. It creates a comfortable climate & keeps moisture out. The fibres of the pod are as soft as down feathers & offer protection from injury. Even the opened shell itself present no danger for your pet, which can use it as gnawing material. Nesting material for all small pets & birds! The Kapok Pod simply lies in the cage. When necessary, the pod must be lightly cracked open to give your pet access to the fibres. Please note: This is a natural product & will therefore vary in size & shape.
