Humans likewise are opportunists... with intelligence they learn to cooperate for mutual gain.
People will do that, but it isn't all about sociopathic cooperation with us, as this implies. We are innately social creatures, and naturally seek to form groups together, even when there is no (non-emotional) personal gain. We have a word for people who cooperate with others only when it gains them something: "sociopaths".
Dogs are that way too. Evolution crafted them to live and hunt in groups, and co-evolution with humans has further crafted them to watch and understand humans and want to please them.
Cats simply are not innately social creatures. They are designed for solitude. That doesn't make them evil, just the creatures evolution has crafted them into. But this means that making them smarter would just make them smarter sociopaths.
