Housing

 Their housing should above all be safe and comfortable for them.
 Cage Size should be at least 3 feet wide by 3 feet tall MINIMUM with never more than half an inch spacing between bars.  Their cage can never be too big, and taller is better than wider.
Don’t let their size fool you!  Even though their small, they still need a lot of room to run, jump, and glide.  Make sure to give them a wodent wheel or other approved glider wheel.  They need a lot of exercise!
Keep in mind your cage size depends on how many gliders you have.  The more gliders, the bigger the cage should be.  You have to allow plenty of room for their pouch, cage sets/toys, and their food bowls (with a glider kitchen if to avoid a huge mess).  They should also have easy access to their water bottle with fresh clean water at all times.  
It’s best to use cages with no shelves.  You can use branches from the pet store, fleece vines, rope toys, and hammocks.  Make sure the doors have a lock of some type so your gliders can’t escape.  If given the chance, they will!
If you’re making a cage, don't use wood!  Wood absorbs the urine and therefore the smell. Avoid galvanized steel because this can cause can cause infections.  Aluminum or chicken wire are also not recommended.
The best material to use is PVC coated wire.  There have been rare instances of bad batches with the coating.  However, PVC coated wire is the most widely used material and is far safer.  Just be aware of your gliders behavior.  If you notice anything out of the ordinary, get your glider to a vet!  Powder coated cages like parrot cages also work well as long as the bar spacing is appropriate.  We use both, so it’s really all a matter of personal preference.   It’s best not to use the cheap bird cages.  These normally rust  with time and that is unhealthy for your glider.  Many of our rescues arrive in rusty bird cages, as a result, we see many health issues.  In the long run, buying a cheaper cage will cause you to spend a lot more money in vet bills.
