>>22928777 (OP)Cat's primary sense is Heating with their amazing cat ears. Vision is secondary.
they can hear 8 times more sounds (i.e. from highest pitch to lowest pitch) and have directional ears with a highly evolved earlobe shape, dedicated to trapping and cleaning sound of noise.
they also have a higher % of brain-matter dedicated to processing audio.
it is beyond super-human hearing.
they can hear your heartbeat
they can hear your neighbour farting from across the street
they hear a car moving over a mile away at night
their hearing is basically like having psyhic powers.
the cat is listening for something.
bare flat walls can make excellent sound amplifiers , hence why cats will stare at a concrete wall.
