Cats do talk and happily do it too. You just need to teach them a language you understand. My cat knows how to use buttons and we can have an argument about when it’s time for food (when he insists on “now” and I tell him “later”, along with “no” so it is no, now etc). Some days he isn’t willing to use the buttons and meows, but after I ask him he reluctantly does.

Also check out BilliSpeaks on youtube. She was an older cat that later in life learned a ridiculous amounts of words.
