It's up there, honest !

Now sometimes in the night I hear a noise of something outside on the balcony, do my people listen to me when I try and tell then...NO !
So this morning I got out there and chased it, but it went up this tree

There's a big hole in the bottom and I'm pretty sure its inside

Then of course it could be hiding a bit further up in the branches

No, its definitely inside, now just how am I going to get up inside there?
