No knowledge of degus but have had pet rats; they are wonderful, intelligent, loving little creatures. They can be trained and are a joy to watch, I think one of the things I liked about them was how happy they were, loved to have a play and a run around but were also happy to put themselves back in their cage which they def saw as home (have had hamsters before and never got the impression they wanted back in the cage). I had two rats then four, group of them is great as they interact together. Get them hammocks for the cage, they love em!
