Apologies if this has been covered before but I've searched but can't find any threads. My youngest son would like a Hamster, after looking into Hamsters I decided that a pair of Gerbils would be better however since making this decision my DH has been speaking to someone about Sugar Gliders. I've looked at some You Tube videos and they look cute but I'm a bit freaked by them launching themselves round the house! 
Can anyone talk me through the pros and cons of Sugar Gliders? Are they expensive to keep? Do they smell? What are they like as pets? Would a 10 year old boy be capable of looking after them with a little guidance? Should they be kept in pairs like gerbils? Anything else you think a prospective new owner should know? 
Any help greatly appreciated.
