I have a question about my sugar glireds -I have three of them, I got them from a previous owner who didn’t take care of them very well. 2 of them are over weight, one is missing half her tail, and the other one is perfectly fine. But anyways.How can you fix a problem of overweight sugar glireds? I have a running wheel in there, a wide variety of fruits, vegetables, and pellets for food, and a nice big cage. They don’t seem to be losing any weight. Help?
