Have you given any thought to how animal and human interests might be commensurated? Even with very good evidence for animal consciousness, it's much more difficult to devise a way of weighing their moral interests.
It's a very difficult question. I wrote up some initial speculations on how I might address the "moral weight" question in Appendix Z7. Each of those "candidate dimensions of moral concern" can also be studied on their own, often in pretty similar ways to how "consciousness in general" can be studied.
