It would not do any good slapping him in the back of the head since its obvious he has no morals concerning a living creature .I know of a "person" (if you can call him that) that has a ball python, turtle and some type of frog living together .I have spent hours trying to inform him his 3 reptiles DO NOT love each other .Sometimes i wish i could place people like this inside of a cage with a lion and a water buffalo so they can love one another .
Who said anything about a mere slap upside the head? When I am met with things like this, my morals towards people of this calibre are about equal to the morals they have towards their animals.
