The Corky Tube is a shelter for rodents made of cork (100% natural product). Ideal for rodents to enjoy life and to shred and as a rest or shelter. Cork has the property that it is more flexible and stronger than just bark and yet it feels nice and soft. Rodents think this is great for gnawing and climbing! Your rodent will enjoy many hours of pleasure here, just like in nature! Do you also take nature back home?
