The Trunkhut Mini, made from 100% natural cork, can be used for multiple purposes. Birds find it a fun challenge to enjoy and sit on it. But the best part is that you can hide everything in it, so that birds are busy for hours to claim their treat. Birds are fans of cork and like to gnaw on it for hours. The Corky Foraging Tube is 100% cork which has been heated for a short period of time against vermin. It is easy to attach to each cage due to a wing nut. Suitable for all curved beaks, from parakeet to macaw!
