I put two wheels in their home because they didn't want to share it. Two degus going in two different directions in one wheel makes for a lot of squeeking! Once in a while one will be on the outside of the wheel and the other inside and that works out fairly well. But the second wheel has solved all our problems.
Notice how I attach the wheel to the top of the cage. This allows for more room on the floor and keeps the wheel very stable while they run.
We are also in the process of getting another dog. A friend is bording dogs for her friend whose marriage ended. She cannot keep her dogs so they are splitting them up. We have decided on getting the pittieX. I will have her next week.
