The dangerous activity of croc feeding is not a joke, it might be enteraining but it is dangerous to people and the animal and it is downright unhealthy and unnatural for the croc. This is a practice that should be stopped and people that particpate, be it physically or simply as bystanders should be made aware of the dangers to themselves and to the crocodile.
Who thinks frozen chicken or a rock on a rope is the natural diet of a 12 foot crocodile? This is cruelty to animals. The crocs end up obese, dependent on hand outs, subject to cruelty of kids throwing rocks, and yes, even people shooting at them.
Nobody wants to chastise a tourist in this era of few and far between visitors, but aren't most of our guests here for the natural habitat, not for parlour tricks?
