Oh, it's absolutely natural. What I object to is the human psyche which can not only enjoy such a thing, but create the scenario unnecesarily as well. Isn't cock-fighting perfectly natural? It is, but we tend to keep cockerels seperate so they don't tear each other to shreds unnecesarily, if we're not the sort of sick fúcks who get our jollies watching animals in distress.
And stop telling me what to do.
Blame those shíte wildlife progammes by ****s like Attenborough that layer emotive, heart string-tugging music over scenes of wild animals doing their thing.
These shows are supposed to somehow educate us, but they are basically just soap operas designed to appeal to our base, crude emotions.
