Which makes me wonder - Are either sets of ears vestigial and non-functional? It might explain why Blake's ears seem quite rigid and don't generally respond to her mood or surroundings the way a feline's ears normally would (although out-of-universe that's probably more due to limitations of the rig than anything else).
