Every night for a few weeks my four cats have been running up and down by the window shaking their tails and making hunting noises. It took a while to find out the cause of all the excitement and it was only after a week or so that I discovered Mr Nibbles (pictured) as I have named him. After several days of sitting by the window with my camera and using a little cheese as bait, I finally managed to get a picture of our elusive night time visitor. At least we know the cats are not crazy now, there really was something out there. Mr Nibbles only visits when all the cats are closed in for the night so for now he is perfectly safe and its great entertainment for the cats.
