HELP! what's wrong with my sugar glider?

Okay first of all this isnt what is a sugar glider's diet. he is probably having an allergic reaction and need to go to the vet. he is only 8 weeks old and should be having fresh nectar, mealworm, fruits, sugar glider pellets, etc, i dont know why there is frozen cubed food, this is not what they naturally eat and eventually will have a vitamin and calcium defiency and you will have a ton of vet bills, so i would take it to the vet then research the real diet of sugar gliders. if you want to own an exotic animal take responsibliltiy and feed it what it is supposed to have, nothing frozen ever.
