Morality concerns human conduct not animal conduct for the simple fact that humans are spiritually rational and intelligent. Animal have sense knowledge, not intellectual, rational knowledge as man. Morality concerns the rightness or wrongness of human acts, judged by the natural and moral laws. Animal do not have the ability or power to make moral judgement. Animals act on instinct and sense knowledge based on the senses and sense memory, no matter how sophisticated it may appear. They are biologically programed, we do not have to teach them what they do. Knowing their nature and program, we can train them to do what we want.
Human because they are rational,and intelligent must be good stewards to the animal kingdom. We must treat them humanely, we possess a higher dignity then they, not because the animal has a claim on the moral rights of man, or it has a moral right. After all we eat animals to sustain life We have a strong tendency to humanize animals.
Poor humanity, some humans worry about the rights of animals but neglect the right to life of a human baby, we got our priorities screwed up. We have a very serious problem in our society, and why, it is what people choose, not worrying about what is right or wrong, and what does that say about society?
