I mostly agree with you. But it seems clear that mammals do have a lot of the same emotions humans do, as those emotions evolved long before humans took the stage. We just inherited them from our earlier ancestors.
Watch Dominion and tell us these animals are not being mutilated, mangled, tormented, slaughtered and murdered.
Animals do not want to die. The will ALL naturally cry, scream, run, fight and generally do anything possible to avoid getting killed. Killing them is murder. Discrimination or unjustified treatment of animals based on an individual's species membership is called Speciesism. The belief that humans alone possess intrinsic value or are the central entity in the universe is called Anthropocentrism.

Animals are not humans, killing an animal is not a murder. Attribution of human traits, emotions, or intentions to animals is called anthropomorphism.
