I don't actually see farming as animal cruelty. My view is that as long as the animal's life on the farm nice (think free range chicken, not battery farms) then there's no issue with eating the animal, since they don't really care about dying and even less about being eaten. Same goes for clothes like leather, as long as the animal has a nice life, what does it matter?
If the whole world went veggie, what would happen to the farm animals? They'd die, farmers wouldn't keep them and they can't survive in the wild. Give them a nice life then eat them, it's for the best.
However, because of this I do not support hunting. Those wild animals can life without humans, and generally they need to survive, either to have children, or look after their children. So hunting wild animals for food and clothing isn't cool, and doing it for fun is barbaric I say. If you can't get your giggles without murdering animals, then there is something wrong with you.
Animal testing is more tricky. Very grey, I understand the arguments of both sides on it, but I figure the best solution is to experiment for medical purposes (or other things that are designed to save lives) and not for things like cosmetics.
And obviouslly abusing pets is horrific.
