For awhile now my 9 month old glider has been displaying repetitive behaviour, most of the night she just does backwards flips off a branch to the roof of the cage then back down to the branch and she does this most of the time, I was worried that she was getting bored so I bought her some new toys which she has taken a slight intrest in, but she still does her backward flips more than anything else she does when in her cage, she does come out for play time every night although over the past month or so I have been ill which meant I was sleeping alot of the time, so she didn't come out as long as she would usually and some nights I'd be feeling too ill to get her out at all

, also she was on her own for about 5 months (I know it shouldn't be done but I spent loads of time with her and my breeder gave me advice on keeping her happy while she was alone) but now she has her baby sister in with her which I thought might cure it but she still does it a fair bit.
So basically I was just wondering if it is a sign of boredom or if it's just something she enjoys to do?
And does anyone elses gliders display any behaviour like this?
Hope that all makes sense and thanks in advance for any help
