These marsupials are certainly cute, but not a pet we, at the cabin, have ever owned. Having spoken to many Sugar Glider owners, they are a very demanding exotic pet, and one that some people have felt was a mistake to get. Sugar Gliders are certainly not pets for the first time owner, or a person who does not have a lot of time to spend with their pet.
Sadly, sugar gliders are often kept in cages that are far too small for a their needs; they also suffer if not kept with a companion, or not carried around for a good portion of the day (at which time they pee, and poop).
Another concern is the age at which Sugar Gliders are sold and purchased. Pet stores often sell retired breeding animals, in other words - old stock, with breeders selling younger animals directly to the public for higher prices than the stores are willing to pay them (indeed stores buy cheap so they can resell high). It is very difficult to tell the age of a Sugar Glider so this is a common trick in the industry.

How To Care For A Sugar Glider
As they love to climb, you must provide plenty of opportunity to climb, ladders, ropes, and even bird toys are good if you cannot find actual toys for sugar gliders. They do require a place to sleep, which should be either a nest box or pouch. Because they tend to urinate in their bed you may want to get 2 pouches, so you can wash one and use the other. They may enjoy a wheel similar to what is used for hamsters.
They are nocturnal, which means they will keep you awake at night if you plan to keep it in your bedroom. They will live for 10-15 years, about as long as a dog, are you prepared for this length of a commitment? Another question to ask is do you have a knowledgeable veterinarian in your area, who can provide care? If you are a person who likes to take vacations, you need to be prepared to provide social care for your Sugar Glider while you are away.
