Regulation of animals

Concerns about the welfare of animals displayed in zoos outside of China have spawned regulations that govern their humane handling, treatment and transportation.

For example, in the United States, the Animal Welfare Act was signed into law in 1966. It regulates the treatment and transportation of animals in exhibitions and research. Cats, dogs, rabbits, hamsters, guinea pigs, nonhuman primates and marine mammals must receive care appropriate to their particular biological needs.

Food must be free from contamination, and must be wholesome, palatable and of sufficient quantity and nutritive value to meet the normal daily requirements for the condition and size of the animal. Animals are required to be fed at least once daily, except as dictated by hibernation, veterinary treatment, normal fasts or other professionally accepted practices.
