Got around the umbrella

Last night I woke at 02:00 AM from cat sounds from my balconny. I have no idea how Conny got around the umbrella, but getting onto my balconny clearly was easier then getting off again. After a short and loud fight he was able to return to his own balconny.

[ time for a better anti-cat barrier... ]

Get around this...

I still kept the 'for sale' sign of my house, which was just what I needed. I did turn it inside out, don't want the neighbours to think I'm leaving...
