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 Sorry, that's seems not to be true, dogs and cats hearing frequency ranges both cover first hundreds Hz, where the most acoustic energy of human voice is. Also the upper harmonics of human speech are wa-a-ay over 1KHz. See:
