Stewie

My cat is stupid, I don't know if all cats are but stewie definately is. Although he's very clever with the road. I have watched him on many occasions wait until all the cars have gone before he crosses.
Parked cars on the other hand are another matter. He frequently waits at the gate when he hears a car on the drive and comes to investigate who it is. He usually ends up getting in the car whilst you are getting out. I do worry sometimes when he doesn't come in at night, I convince myself that he's jumped in a car and is halfway across the country.
I don't know who's dafter, me or the cat?
