H.R. 2976 replaces the Animal Welfare Act’s statutory definition of “animal” to include cold-blooded species — explicitly citing reptiles, amphibians, cephalopods, and fish — while preserving the Act’s existing exclusions for certain laboratory-bred rodents, birds, horses not used in research, and farmed animals used for food or fiber. The amendment also confirms that the Secretary may add other animals to the Act’s scope and makes a textual clarification that “dog” covers all dogs including hunting, security, and breeding animals.
Why it matters: the change would bring many animals that previously fell outside the AWA into the Act’s regulatory framework — potentially triggering USDA licensing, inspection, recordkeeping, and humane-care requirements for a broad set of research facilities, zoos and aquaria, exhibitors, and segments of the pet and breeding trade. The text is narrowly procedural (an amended definition), so practical effect will depend on downstream agency guidance, species-specific standards, and resource allocation at APHIS.
At a Glance
What It Does
The bill amends 7 U.S.C. 2132(g) to define “animal” to include cold-blooded animals such as reptiles, amphibians, cephalopods, and fish, while retaining several statutory exclusions and giving the Secretary discretionary authority to add other covered animals. It is a definition change rather than a standalone set of new standards.
Who It Affects
Universities and private labs that use cold-blooded species in research, zoos and public aquaria, exhibitors and traveling shows featuring reptiles or cephalopods, commercial breeders and pet retailers in the exotic-pet market, and USDA/APHIS as the implementing agency.
Why It Matters
Changing the statutory definition pulls previously excluded species into an existing regulatory regime with inspections, licensing, and enforcement mechanisms; that shift will force agencies and regulated parties to translate warm-blooded–centric rules into standards for ectotherms and other taxa and to decide which farmed or ornamental operations remain excluded.

What This Bill Actually Does
H.R. 2976 is short and surgical: it does not spell out new performance standards or penalties; it alters the triggering language of the Animal Welfare Act by expanding the Act’s definition of “animal” to include cold-blooded taxa. Because the AWA’s protections, licensing regime, inspection authority, and enforcement powers all flow from that statutory definition, any animal newly captured by it would become subject to the Act’s existing framework unless a specific exclusion applies.
The bill names examples — reptiles, amphibians, cephalopods, and fish — to make clear that ectothermic vertebrates and at least some invertebrates are intended to be covered. At the same time the text preserves longstanding exclusions: birds, rats of the genus Rattus, and mice of the genus Mus when bred for research remain outside the Act; horses not used in research remain excluded; and the Act continues to exclude “other farmed animals” including livestock, poultry, or fish used or intended for use as food or fiber or for production-improvement purposes.
Those paired inclusions and exclusions create immediate line-drawing tasks for agencies and regulated parties.Because the bill only changes a definition, the visible next steps would be administrative: APHIS must determine how to apply AWA regulatory instruments to species with substantially different husbandry needs (water chemistry, temperature control, UV exposure, salinity, etc.), decide how to treat mixed-use operations (for example, an aquaculture facility that raises ornamental fish alongside food fish), and issue guidance or rulemaking to address gaps where current standards assume mammalian care. The statute’s clause giving the Secretary authority to designate other animals provides a pathway for further expansion, but also concentrates discretion in the implementing agency.Finally, the amendment clarifies that “dog” in the Act includes all dogs — explicitly covering hunting, security, and breeding dogs — removing any lingering ambiguity that those categories might be outside AWA coverage.
That clarification is textual but matters operationally because it forecloses an argument that some working or breeding dogs fall beyond the statute’s reach.
The Five Things You Need to Know
The bill amends 7 U.S.C. 2132(g), replacing the statute’s definition of “animal” to add cold-blooded animals as a covered category.
The text explicitly lists reptiles, amphibians, cephalopods, and fish as examples of cold-blooded animals that the Act will cover.
The bill retains the AWA’s exclusions for birds, rats of the genus Rattus, and mice of the genus Mus when bred for research, as well as horses not used in research.
The statute continues to exclude ‘other farmed animals’ — including livestock, poultry, or fish used or intended for use as food or fiber or for production-improvement purposes — creating a specific carve-out for farmed food fish.
The amendment adds a standalone clause clarifying that ‘dog’ means all dogs, explicitly including dogs used for hunting, security, or breeding.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
This single-line section names the statute the “Cold-blooded Animal Research and Exhibition Act.” It has no operative effect but indicates congressional intent and provides a reference name for citations and implementing materials.
Replace the AWA definition of ‘animal’
Section 2 substitutes a new subsection (g) into the AWA. Mechanically, changing the definition is the lever: every provision of the AWA that applies to “animals” — licensing, inspection, standards of humane care, dealer and exhibitor registration, transportation rules, recordkeeping, and enforcement — will now reach animals brought within that definition unless another exclusion applies. Because the bill does not rewrite implementing provisions, agencies will implement the change by interpreting current rules against a broader set of species.
Inclusion of cold-blooded animals and Secretary’s discretion
This clause defines ‘animal’ to include warm-blooded animals, cold-blooded animals (with parenthetical examples), and any other animal the Secretary determines is used for research, testing, experimentation, exhibition, or as a pet. The statutory grant of discretionary authority gives the Secretary a formal route to add further taxa without new legislation, but it also places a big administrative burden on the agency to decide which animals meet the statutory uses and to publish clear guidance for regulated parties.
Preserved exclusions, including farmed animals and lab-bred rodents
This subsection keeps the AWA’s long-standing carve-outs: birds, Rattus and Mus bred for research, horses not used for research, and ‘other farmed animals’ used for food or production purposes (explicitly including fish used as food or fiber). Practically, that means ornamental and companion fish would be within scope while aquaculture operations producing food fish would generally remain outside the statute — a distinction that demands operational definitions from APHIS and will be a focus for compliance disputes.
Clarifies scope for dogs
This short clause states that ‘animal’ as applied to dogs means all dogs, including those used for hunting, security, or breeding. The provision closes argument that certain working or breeding dogs might be excluded from AWA coverage and signals congressional intent to keep the statutory protections broad for canines.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Reptile, amphibian, cephalopod, and ornamental-fish animals and advocates — a statutory baseline for humane care and oversight that did not exist under the AWA for many cold-blooded taxa.
- Zoo and aquarium visitors and animal-adopter consumers — potential for standardized welfare practices and clearer accountability at public exhibits and pet retailers.
- Researchers studying cephalopods, certain fish, and other ectotherms who seek consistent ethical standards and public confidence; clearer statutory coverage can harmonize institutional oversight.
- Animal-welfare organizations — clearer statutory footing to pursue inspections, compliance actions, and public reporting when cold-blooded animals are mistreated.
Who Bears the Cost
- Research institutions and private labs that use cold-blooded species — will face new compliance burdens (registrations, inspections, possible facility upgrades) and associated administrative costs.
- Zoos, public aquaria, exhibitors, and traveling shows featuring cold-blooded animals — may need to modify husbandry systems, obtain USDA licenses, and revise recordkeeping and transport practices.
- Commercial breeders, small exotic-pet retailers, and reptile/amphibian shows — regulatory compliance could impose permitting costs and operational constraints that disproportionately affect small operators.
- USDA/APHIS and the federal budget — the agency will need to allocate staff, inspectors, and possibly develop rulemakings and species-specific standards without funding in the statutory text.
Key Issues
The Core Tension
The bill confronts a central policy trade-off: extending statutory protections to taxa that previously lacked them improves animal-welfare coverage and public accountability, but it simultaneously imposes regulatory compliance costs, forces agencies to craft species-appropriate standards from scratch, and risks either overbroad rules that misfit biological needs or under-resourced enforcement that leaves coverage theoretical rather than real.
The bill’s substance is a definition change, which yields broad practical consequences but leaves many technical questions unanswered. The central implementation challenge is translating regulations and humane-care standards historically written for mammals and birds into requirements appropriate for ectotherms and cephalopods.
Water quality, tank life-support systems, thermal gradients, lighting spectra, and species-specific behaviors are materially different from the needs of warm-blooded animals, so APHIS is likely to face pressure to develop new, species-specific standards rather than rely on existing, ill-fitting rules.
Another unresolved issue is the statute’s treatment of fish: the bill includes fish in the definition while the exclusions explicitly exempt farmed livestock, poultry, or fish used for food or fiber. That creates practical ambiguity around operations that straddle categories (ornamental vs. food aquaculture, direct-to-consumer breeders who also sell broodstock), and will require administrative criteria to sort covered from excluded activities.
The Secretary’s discretion to add animals provides needed flexibility but also centralizes line-drawing in agency hands, raising the prospect of uneven application, litigation over arbitrary determinations, and compliance uncertainty for regulated parties.
