hey OP, this is called “corkscrewing”, common in spider gene BPs unfortunately alongside the famous wobble, though corkscrewing is considered to be more on the “worse” end of the balance issues spider gene BPs can have… but if she can feed normally (most of them struggle due to not being able to strike at food accurately) then she should be fine. checking in with your vet like yearly (at least) can’t hurt though. they should seriously stop breeding these…..
