Man. I love this photo. It sums up just how interfering, impulsive and generally quite daft your average moggy is.
Why grab at this man's hair as he is walking past? Are you a kamakazee kitty? Did you think it was 6 foot tall blonde mouse? What are you doing on up there anyway? You're going to hurt yourself, especially if your claws get stuck in that fuzzy barnet and you end up being dragged off the roof and down the street, flapping and yowling as you hang by a solitary paw, scrabbling desperately at his neck and back, trying to get a better grip, and he bats frantically at you with a newspaper.
This ain't the kid of story you're going to be able to regale your mates with down at the milk bar. The only person you'll be sharing this experience with my son, is the vet.
