Hemoslug

A new technology, originating on the West Coast of the USA by scientists working for the vampire mob, in which human subjects are bred for feeding purposes. The potential hemoslugs are kidnapped from their parents at birth, and fattened up over time with growth hormones and an abundance of food. Cholesterol levels are kept low with chemicals that have been engineered to keep the creature alive during the process. A hemoslug can be bought as livestock, and just one (often reaching a weight of seven to eight hundred pounds) can provide a steady supply of living blood for up to a year before the drain becomes too much. It is regarded as an illegal practice for the time being, but the project is still making advancements all the time. Vampires are hoping to make it a marketable business in the next few years. Hemoslugs are already used openly in various parts of the IceZone.
