Remember this is by no means a complete list.
Sugargliders are an
EXOTIC animal & require specialized care!
They do NOT make good pets for everyone!

Imagine having an infant for the next 16 years.
That is what it is like to own a glider.
Yes, there is both work and rewards
but what are you doing in the next 16 (or more) years?
Does a glider fit into that lifestyle?

Please research BEFORE you buy. Help to stop filling rescues with unwanted gliders!
If your glider escapes catching them can be incredibly difficult,
especially if they have not bonded to you yet.
It can take hours, days, weeks, and it’s not fun. There is also a good chance you may never find your glider alive.
Trust me, you will not want this to happen.  
These tiny acrobats are fast and very agile. They can hide anywhere!

They require a specialized diet, that you need to make. It is NOT sold in stores!
Although some will lie and tell you they can eat pellet foods or cat food but this is NOT TRUE!
Most people find peeling, slicing, and dicing fresh fruits and veggies every night a little tedious.  
Not to mention handling LIVE meal worms for your glider's protein requirements.

Gliders require large cages.  
They might be small but sugargliders are nothing like a hamster.  
Gliders - GLIDE!  
That means they need room to do so.  
The larger the cage, the better it is for the glider.  
The bar spacing on the cages should be not greater than a half-inch.  
Anything wider than 1/2 - inch could allow a glider to escape or create a strangulation hazard.

Veterinary costs can be expensive.  
If a glider gets sick, since they are nocturnal, it is almost always noticed at night.
This mean an expensive emergency vet visit in the middle of the night
and the illness or injury bill itself can easily set you back hundreds!
If you own a glider you should have a minimum of $1000 set aside for an emergency vet fund.
Sugarglider Cons
There are many negative aspects to owning a sugarglider. However, a
negative trait to one person may not be a negative to others... I have
gathered a general list of the most common "deal breakers" for people
researching sugargliders but please be sure to research further, as this
list is NO way a complete list.

They’re nocturnal.  
They sleep all day and wake up when most people are getting ready for
bed. They want to be fed at night and they want to play at night. Not to
mention they are very vocal at night! I definitely wouldn't recommend
them if you are a light sleeper.

Gliders can NOT be potty or litter trained.
They will pee and poop whenever, and where ever, they feel like it.  
Get used to carrying a small container of “baby wipes” and hand
sanitizer with you!  
You can NOT “potty-train” a glider.  
Some have claimed that you can but I've owned gliders for over 5 years
and
I've NEVER seen a potty-trained glider.
