I can't agree with that. An animal acts on instinct, not premeditated reasoning.
No matter if they are misguided, wrong, acting from hatred, or many other reasons, they are still human.
In any case I wouldn't condone the torture of an animal either.
While there is a difference between soldiers in the military, to be treated under the Geneva convention, and terrorists, there is NO justification, IMO, not even close, for torture.
