Known, mainly, for their impressive speed on the race track, Blue Runners, a subspecies of the common runner, are also famous among owners for being extremely hard to raise. After years of selective breeding to achieve the fastest runner, breeders' efforts had led to unexpected, and some times undesired, side effects. While its now famous blueish sheen is harmless enough, two other unintended consequences cannot claim the same. The first one is that they have become notoriously picky eaters. These once opportunistic omnivores that fed on whatever they could find now cost their owners thousands in monetary loss as they ignore prime cuts of meat and fresh fruits and vegetables. Paradoxically, they have also developed an extreme case of pica syndrome, mainly geophagia, lithophagia, metallophagia and kleptophagia, eating things improper for consumption, which led to many owners putting metal bands across their necks to try and stop them from swallowing anything to big that could end up killing them. Despite all the hardship and problems that their selective breeding has caused many still choose to raise a Blue Runner with hopes that they will bring them fortune on the race tracks since a healthy female Blue Runner is still the fastest among the wide variety of runners.
