Here's a thread with a bunch of fruit/veg mixes already worked out for you, so you don't have to worry about the math
http://www.sugar-glider.co.uk/forum/index.php?topic=2165.0Let the mush thaw before giving it to them and their cat bisquits should be whole, so they have something to crunch (good for their teeth)

You can give a variety of protein sources, but a good quality cat food (iams or james wellbeloved) should be the main one. Chicken, egg, yogurt, etc

it could just be because i use a crappy mac and it messes things up!
