Very good definition! I believe the care and health of the animals should be the first priority if you are just a collector or you are a breeder. Also as a breeder you need to be ready to take care of each baby that is born for as long as it takes. You may have plans to sell them, but they may never sell! At this point a responsible is ready to feed and care for those snakes properly. Also regardless of the situation I don't think a breeder should sell a sick snake even if in person and the buyer knows what they are getting into. This is just a bad practice that should be avoided at all costs.
