Cat flap.

Wilson now has his own door to the outside world. We put a cat flap in a couple of weeks ago. He's an old hand at cat flaps...no problems. Fitting it proved to be traumatic though. Lets just say it was a rushed job...and there is now lots of sticky tape around it, making sure it doesnt come away from the door every time Wilson uses it.
So far he hasnt brought anything in....there are lots of dead birds and mice outside the back door....but thankfully none in the house.
