Hypothesis: cats have a mental architecture — brain hardware — that's amenable to learning as much as that of any other mammal with a cortex; but they don't come with instinctive knowledge of certain mental schemas — brain Operating System software, essentially — required for social intelligence. Those mental schemas instead have to be taught/communicated. - Have you ever seen a "cat raised by dogs"? They develop the same mental schemas around socialization that dogs do; begin to understand the sort of "pack" structure and reward norms that dogs think in terms of; and so end up trainable exactly like dogs, using e.g. social-status gratification/reassurance as a substitute for food. And often, you won't actually have to explicitly train a "cat raised by dogs"; cats are seemingly highly skilled at modelling (i.e. witnessing others earning rewards for a behavior, and then self-motivatedly learning to mimic that behavior), and so a cat that hangs around trained dogs may teach themselves "tricks" it observes the dogs doing. - Have you ever seen a cat taught human language using AAC (Augmentative and Alternative Communication) devices, a.k.a. "button training"? They can very quickly absorb human mental schemas, learning to not just to favor "using their words" to signal their needs, but also, through that, to begin modelling the world narratively, telling stories about what they witnessed other-person A doing to other-person B. If you communicate the terms "soon" and "later" to them, they will begin asking about the future, expressing a curiosity about whether events (e.g. a person coming home from work) will happen near or far in time. These are not things that cats seem to instinctively think about, until they have the mental schemas to think about them; but once they absorb these schemas, they do engage with these topics!
