Welcome to Paw Talk. It is very important that a Sugar Glider recieves a well balanced diet. Along with fruits and veg they do need protien and also extra vitamins.
There is a lot of information on diets here:http://www.sugarglider.net/links/pag...ion/index.html
I personally feed the BML diet http://www.sugargliderinfo.com/Nutri.../leadbeat.html
and find it to be excellent.
Whichever diet you do choose to follow please make sure it is a proven one.
I see you are in the UK and I don't know what availability is like for all the ingredients over there as a lot of the diets are US based. I do know that there are a few UK owners on this board though http://www.sugarglider.net/ubbthread....php?Cat=0&C=3
so they also maybe able to help you.
Here a list of glider safe foods:
Papaya, apples, figs, pears, kumquats, raspberries, cherries (no pits, they're toxic), blackberries, seedless grapes, plums persimmons, mangos, watermelon, strawberries, cranberries, apricots, cantaloupe, honeydew melons, casaba melons, kiwi, peaches and pomegranates. (Take out pits and seeds (don't worry about the smaller seeds i.e. strawberries, kiwi, etc.)
Peas, green beans, carrots, sweet potatoes, collard greens
, mustard greens
, spinach, squash, celery, watercress, broccoli, cauliflower, pumpkin, Brussel sprouts, asparagus, yams, corn.
