You've obviously had some nasty "experiences" on your property, Chav. I sympathise with you but, you'd know this if you had any real knowledge of cats, it's just the same as your analogy of a child's behaviour. Cats are creatures of habit and they will chose a favourite spot for defacation. If the "spot" is chosen for them, from a very early age, they will stick to it (in a manner of speaking) for life.
Incidentally, if your child did as you suggest I would beg you to take him to a psychiatrist without delay. Conversely, of course, I could just get him with an air-gun.
