Websterz,
I wouldn't worry about it too much, my wife used to have a bad habit of running over ours when backing out of the drive.
I think it is three at last count.
We only have one left for her to have a go at now, and he is living on borrowed time, after being run over twice on the main road. When he hears our car start, you can't see his a**e for dust.
