Glad Ollie is ok. I check for studs when ever I hang stuff, because almost everyone I ever hung has fallen. Stirling has flown off as has Ollie. Sydney however, hangs on for the fall of his life, and doesnt even attempt to flap his wings....(he;s not the sharpest tool in the shed!

)
the thing is, even when they are playing and flappin around on the boing, they can untwist it out of the ceiling. thats Sydneys case more then not.
