Cognitive Abilities and Moral Standards

Question 2: What role does cognitive ability play in the moral standards we can expect of non-humans?

When we think of ethics and the fact that it takes into account humans and their functions, limits, and abilities it would seem as though those same things would be key factors in considering the moral standards to which we can hold non-humans. I believe the abilities and limits humans have make it so we have moral limits that we cannot pass; therefore, it is harder to impose moral standards on non-humans that may not be able to understand the reasons that they should meet any such ethical standards. So, I would say yes, cognitive ability does play a role, perhaps even a big part, in the idea of giving non-humans the same moral standards as humans. I also believe that this factor would change whether we give non-humans moral value or not.
