The pattern that makes us think things are cute (=young) is pretty universal among animals. It includes big eyes, big heads in relation to the rest of the body, small noses and a small mouth. We find things like cats super cute, because even adult cats are pretty close to that pattern, compared to f.e. adult humans.

So I guess that an animal whose adult form is less close to this pattern than ours would probably think of us as especially cute?
