Wildlife At The Window

So here I am sitting at the computer and I hear a tap, tap, tap at the window. When that happens it's usually Charlie our cat wanting in. His habit is to tap on the window. So of course when I heard a noise at the window I thought it was him. 

I pulled the curtain back to see if it was him, nothing there. Tap, tap, tap again, so I looked again, nothing. I was getting annoyed with him.

It happened again but this time I went to the door to see what was going on. It was a Blue Tongue Lizard at the window not poor old Charlie.
