Soylent Green is superior to it's predecessors, Soylent yellow, Soylent Red, and cat food in that it is not red, yellow, or made out of cat food. Soylent is superior to Hufu, if for no other reason than you can get Soylent by mail order. It should be made clear, however, that sometimes Soylent green is cat food, and that sometimes cat food is Soylent green. The only way to tell is to feed it to your cat. If nothing happens you can be unsure of it being either Soylent green or cat food. If the cat dies it is your own fault.
