The main purpose of this legislative text is to amend the Animal Welfare Act to include cold-blooded species, such as reptiles and fish, under the definition of "animals." This change aims to enhance the protection of these species in contexts like research, testing, and exhibition, ensuring they are treated with care and respect. Key provisions of the amendment specify that the term "animal" will now encompass both warm-blooded and cold-blooded creatures. This includes reptiles, amphibians, cephalopods (like octopuses), and fish.
