When offering advice, please keep in mind James Chin does NOT live in the United States.
What we have available to us may or may not be available to him. He is feeding his glider with what is currently available to him. We also do not know how knowledgeable vets are there, about glider care and husbandry.
This is a world wide forum, if the diet sounds off or weird to you please ask what country the Op is in before making suggestions on what they should feed or not feed. We have some seriously different standards of living for gliders here in the states than other countries do or have available to them.
I realize every one just wants to help. However, don't be afraid to ask questions before giving advice so you have the bigger picture of what your dealing with and can give educated, helpful advice.
