The Cat is Self-Domesticated
Unlike other domestic animals, the cat is self-domesticated.
It chose to live in close proximity to people because it was in its interests to do so, a natural selfishness that remains at the core of domestic cat behavior to this day.
This self-domestication was relatively recent, occurring long after we had domesticated the dog.
The cat's ancestors needed specific psychological and physiological traits to help them to infiltrate the new and unique ecological niche of the human settlement.
Under the altered environmental pressures, both physical and behavioral changes occurred, creating the most successful ever of all the species of cat: the domestic cat.
