I often get locked out of my house, due to wearing different trousers a lot then not wearing the ones with my key in them. So I'll wait outside until someone comes home. Anyone who's been locked out know it is very boring. I would do a lot of thing to stop myself from being bored.
One thing I did was put my cat on top of our car (Everyone must have gone out walking). Now, our cat was about 18 then and not very smart. So, he tried to first get off the car the from the back end, but it was quite verticle, so he slip but luckily got stopped by the windscreen wipers. Stupidly he jumped back up to the top of the car again.
Next, he tried to get off the car from the front. He stepped onto large front window and began to slip. To stop himself, he out his claws out. For an old cat, he claws were very sharp. he dragged them all the way down the window. Now, there was three big sratches in the windscreen.
I told Mum hooligans did it while we were out. I didn't want Chips to get in trouble.
