Liberationists argue that animals appear to have value in law only in relation to their usefulness or benefit to their owners, and are awarded no intrinsic value whatsoever. In the United States, for example, state and federal laws formulate the rules for the treatment of animals in terms of their status as property. Liberationists point out that Texas Animal Cruelty Laws apply only to pets living under the custody of human beings and exclude birds, deer, rabbits, squirrels, and other wild animals not owned by humans, ignoring that jurisdiction for such creatures comes under the domain of state wildlife officers. The U.S. Animal Welfare Act excludes "pet stores ... state and country fairs, livestock shows, rodeos, purebred dog and cat shows, and any fairs or exhibitions intended to advance agricultural arts and sciences." There is no mention in the law that such activities already fall under the jurisdiction of state agriculture departments. The Department of Agriculture interprets the Act as also excluding cold-blooded animals, and warm-blooded animals not "used for research, teaching, testing, experimentation ... exhibition purposes, or as a pet, farm animals used for food, fiber, or production purposes".
