I have no idea, how chinchillas live. We have been visiting a former friend and there was a chinchilla alone in a very smal birdcage. He could only jump from ground to a little house upstairs. I have offered the person one of my old degucages as a gift, but he said, the chinchilla has lived in a bigger cage and it behaves curious. I´ve asked, if he could take a 2nd chinchilla to accompany his one. But he claimed, his one ist to old. It is about 18 years old.
I feel a lot of sorry for the poor chin. But I even don´t know, how I can help him.
