If you really want to post a link to a snake munch I guess it's ok.
I have always said this - those people who think cats and dogs are cute - starve them and they will sudennly stop seeing you as benefactor and instead see you as food. Humans have morals, animals do not - simple.
As I mentioned earlier, animals are rarely, if ever, at fault, it's their human owners.
Whoever owned the Boa that ate the cat was at fault for not feeding it, an irresposnsible owner who should rightfully be banned from keeping pets.
Who breeds Pitbulls, who trains dogs to fight? Who organises cock-fights? Dancing Bears?
Savages? Animals? Humans? Blur the line...
Unfortunately when it comes to owning pets a human being does not have to own a licence proclaiming he/she has a brain.
