It would be best to get either two females, two neutered males or a neutered male and a female as your first gliders. Give yourself a year to get very comfortable handling your pet gliders.
They are wonderful pets - but not for everyone. See how sugar gliders really fit into your life. Make sure you are very comfortable handling them, trimming nails, preparing their food, cleaning the cage etc.
You need to think ahead to make sure sugar gliders will be a good fit for you not just at the present time - but for up to the next 15 years.
The amount of time you can devote to your gliders each evening may change with your circumstances - if you are in school now - life will change when you graduate and get a full time job. If you are working now - a new job or an increase in responsibilities might cut into your glider play time. If you do not own your own home - moving to another apartment or home can be complicated by limitations on the pets you can have in a new apartment - or the pet deposit might be costly.
If you take vacations - you will need a sitter to care for your gliders while you are away if you cannot take your gliders and all their equipment and food with you.
Before you commit to the car of a breeding pair - be sure you are completely comfortable with pet gliders first. If you choose to breed later - be sure that should a joey be rejected that you are prepared to care for and feed the joey every few hours around the clock for about 6 weeks. Not everyone can devote that amount of time to care for a tiny pet 24/7 if necessary.
Keep in mind that intact male gliders can be pretty smelly creatures. If odors bother you, breeding gliders may not be a good choice.
