This is one of those contreversial questions, you will get different answers from different people.
When I got my first chinnie, he had a degu living with him with no trouble what so ever. I do not believe there is anything wrong with it personally, but I got so much flack from some people that I stopped, and they were SO HEARTBROKEN! I think the only concern is the food, what I did for that, Is I fed them mazzuri and the Blocked
guinea pig pellets, they would take the blocks out and hide them, so the chins never got them anyways, but as i said, you will get different opinions
