And why is their aim so bad? I've heard the notion that they're trying to cover their marking but I don't quite understand that. I thought the purpose of marking was so that other animals *would* notice it, and it seems covering it would defeat that purpose. I've always found their kicking amusing.
There are certain areas in my neighborhood with hay covering the ground. I always have to pick up all the hay and put it back after Chance kicks it onto the street! I could just say "no" and she would stop kicking but it just seems so important to her to kick!
