A dog is able to learn up to 250 words and gestures and count up to 5:
Equivalent to a human aged 3.

A cat doesn’t give a damn, and is sick of your crap:
Equivalent to a human aged 48.

Dog can hear us. Cat can't.

Cat's mid hearing range is about 1-1.5 octave higher than Dog's or eg: the human voice. Not just that, their perception of time is faster than ours (we look slo-mo)

When a cat lives with someone who is mute-deaf the cat will learn to understand gestures and even to make their own gestures to communicate what they want

( Personal I think a cat's "miaow" is likely the closes sound a cat can make to emulate how we sound to them )

@artemissian @juglugs Your last point is true. They meow to communicate with human voice.
