AFAIK cats aren't domesticated. It's more that we have a deal with them. They moved in on their own when they realised humans provide shelter if you hunt their pests.
They aren't as domesticated as dogs, that's for certain, but you can't just take a bobcat or other small wild cat kitten and expect it to be a good pet that won't try to attack you when it gets older. Even the more exotic breeds of housecat like the Savannah (crossbred with wild servals) have behavior issues. Housecats have been domesticated to the degree that they continue to act kittenish in adulthood.
