I recently had an autopsy done on one my sugar gliders that passed away, the vet concluded that he had heart disease (this was not the actual cause of death though but was form the cause of death). I was trying to do research since she stated that it is most likely hereditary but I can't find anything on heart disease in sugar gliders. Does anyone have some information, a website I can look at, or an article I can read that involves heart disease in sugar gliders?

I don't know that there is anything published on heart disease in sugar gliders. At least I haven't seen anything. Have you tried a google search?

ETA: Actually when I do a google search, the only thing that comes up is your posts
