^Very nice facts. You may be right, but as for the "perception defines our reality" part of the subject, I must agree. We know what we recieve and conclude, and it all depends on the brain's functions. So we live in this world, we have certain 'characteristics', and other creatures have other characteristics, and diferent views, so each must have a different 'reality', because we are only what our brains do.
I'm sure you share the same view, right?
And if I'm bambling something unrelated, then sorry.
Note: I believe that cats don't see us as bigger cats, when I see study results, which you provided, so yeah, whatever science proves I walk with.
