Can a sugar glider live in a parakeet cage?

You will probably need a slightly bigger cage. I have two gliders and Their cage is huge, 6 foot high and 4 foot on each side. They need at least 3-4 bonding time each day, if you can not be there a lot during the day, get 2. They can die from depression and loneliness. They have a very strict diet too. You also need to find a vet for exotic animals, a regular vet will not take them.
