Adoption/Rehoming/Retirement of Laboratory Animals after Research

Scope Note

NIH supports and encourages a research institution’s decision to adopt/rehome/retire their research animals following the completion of the NIH-supported research. This decision is completely optional and up to the research institution, should they deem the animals appropriate for adoption/rehoming/retirement. Also, as mentioned on this FAQ, NIH reminds institutions that their policies must clarify the disposition of animals acquired for research once the research has ended, which may include adoption/rehoming/retirement.

NIH developed a webinar to help and encourage research facilities create adoption programs. Viewers can learn about:

  • Establishing adoption, rehoming, retirement, and release programs depending on the animal species
  • Developing institutional policies and criteria for suitable animals
  • Logistical considerations
  • Potential issues to overcome depending on state and local requirements 

Research institutions have the flexibility to determine if they can create an adoption/rehoming/retirement program that meets the needs of the animals in their care. Successful post-research adoption/rehoming/retirement programs:

  • Determine if rehoming is safe and medically appropriate, considering any effects on the animals and their well-being, human safety, and potential environmental impacts
  • Address unique challenges, such as if extensive conditioning and socialization are needed, to successfully integrate into a home setting which may include other animals and/or children. 
  • Meet pertinent federal, state, and local laws and regulations for the transfer of animal ownership
  • Coordinate with local animal shelters when appropriate

NIH funds are allowed to pay for certain post-research efforts related to adoption/rehoming/retirement of animals deemed suitable for adoption/rehoming/retirement (see this FAQ and NIH Guide Notice). Allowable costs may include:

  • Charges incurred to prepare for the transfer of the animal upon completion of the research (but do not extend beyond the transfer to support the care and upkeep of the animals)
    • Developing health certificates, transfer of ownership agreements, and other pertinent legal documents that identifies the terms and conditions of the transfer, health of the animal at the time of the transfer and relinquishes the institution of responsibility for the animal once the transfer has occurred.
    • Diagnostic testing, appropriate vaccinations, and surgical sterilization that may be performed prior to the transfer as deemed necessary by the Attending Veterinarian
 

Note

NIH assumes no legal responsibility for any adoption/rehoming/retirement program, or any matters arising from or related to the adoption/rehoming/retirement of research animals. 

These programs require time, monetary resources, staffing, and expertise. Careful consideration must be given to individual circumstances. Adoption/rehoming/retirement programs should be initiated only when they contribute to the safety and well-being of the animals and the individual(s) receiving the animal. When it is a safe, feasible, and appropriate option, adoption/rehoming/retirement is a rewarding process for both researchers and animals. This NIH Record article also includes information about NIH’s post-research animal adoption/rehoming/retirement program.
