they seem to love the deer cocaine or similar stuff but the chemical in it is nothing more than MSG a preservative that makes chinese food and potato chips taste so good along with a million other junk food products.the problem is that it goes by quite a few trade names to confuse the customers. DICALCIUM PHOSPHATE is one of them i believe. its the taste that gets them addicted but i dont think it has any nutritional value. any chemists or nutritionists out there?
