Cats can seem aloof and not caring, but according to Discovery News, it's just an act. Cats have evolved not to be demonstrative. If they're sick, for example, they hide it, because in the wild predators pay attention to weakness.
Cats have cohabited with humans for 10,000 years, and domestic cats have developed an ability to communicate with us. Cat lovers seem to understand them, for the most part.
Discovery News point out that cats behave like kittens around their humans, and humans treat cats similar to the way we treat babies. In order to form such tight relationships, cats need to recognize and pay attention to humans. The study shows that cats might not communicate through grand gestures, but even when we think they're ignoring us, they're paying attention.
