Are any breeds of domestic cat bred primarily for their intelligence? If so, which breed(s)?
By "Intelligence", I mean problem solving ability. This would include such things as the cat attempting to open doors using the handle where other cats would simply miaow to be let through, or turning lights on/off, or learning by example by watching another cat or human perform a task.
By "primarily", I mean that after consideration of the health of the kittens, the parents are selected first for their intelligence and their appearance is only considered after that, unless it is a matter of the breed's health.
I am aware that breeds like Abyssinians, Bengals and Siamese are known for their intelligence, but is the intelligence of any of these or other reputedly intelligent breeds accidental, secondary to that of appearance, or primarily selected for?
