Doing a quick google on Sugar Gliders - they sound like cool animals -- but very time intensive:

It's also a nocturnal animal (same as a chin) so if your daughter has a reasonable bedtime, she's not going to get much "playtime" with this pet. The beast will sleep all day and play all night.
I have been trying to find it and can't. Someone on the the wonderful world that is the web -- there's a quiz that you can take and it will give you best pet suggestions for you (and it doesn't include just dogs and cats) I just can't find it.
