reading the scope in the req book, I note that cats,dogs, birds, and in some definitions chickens are not covered by the regulations,
the definition of livestock from wiki is
Livestock is commonly defined as domesticated animalsraised in an agricultural setting to produce labor and commodities such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to those that are bred for consumption, while other times it refers only to farmed ruminants, such as cattle and goats.[1]Horses are considered livestock in the United States.[2]The USDA uses livestock similarly to some uses of the term “red meat”, in which it specifically refers to all the mammal animals kept in this setting to be used as commodities. The USDA mentions pork, veal, beef, and lamb are all classified as livestock and all livestock is considered to be red meats.
