The legend of the Burmese Cat:
Thai monks who were in training to be priests were each given a Burmese with this single instruction: “Please the cat.” Through centuries of this, the Burmese lost much of their cat behaviour. For instance, they are extremely trusting of anyone and everything, so they let you carry them around. The downside to this is that they can never be let outside; they’d walk right up to a dog and try to chat it up. Or beat it up.
That does seem like it would be a good way to teach humility.
