What Are Lab Cats and Why Are They Used in Research
Lab cats are domestic cats used in regulated biomedical and behavioral studies. They help researchers model human diseases, test medical devices, and study neuroscience, genetics, and infectious diseases. In 2025, institutional animal care and use committees, or IACUCs, oversee most U.S. lab cat protocols under the Animal Welfare Act and Public Health Service Policy https://www.aphis.usda.gov/animal-care.
Regulations require institutions to justify cat use, minimize numbers, and follow the 3Rs framework: replace, reduce, refine. Federal agencies such as the National Institutes of Health and the U.S. Department of Agriculture track annual reports on covered species, including cats, to monitor compliance and trends https://www.aphis.usda.gov/animal-care.
Current Research Areas and Funding for Lab Cats
Common 2025 research areas for lab cats include neuroscience, HIV/AIDS studies, cardiovascular physiology, and regenerative medicine. Cats serve as models for diseases such as hypertrophic cardiomyopathy, diabetes, and certain infectious conditions due to similarities with human physiology.
Funding and Institutional Use
Public funding for lab cat research flows mainly through federal agencies like NIH, while private companies and universities conduct additional studies under strict oversight. In recent years, NIH funding allocations for lab animal programs have been tracked in annual reports that include data on cats, dogs, and other species https://www.nih.gov/.
Regulations, Ethics, and Alternatives for Lab Cats
U.S. law requires institutions to maintain IACUCs that review and approve every animal study protocol, including those involving cats. IACUCs assess pain management, housing, training, and endpoints to ensure compliance with federal standards and institutional ethics policies https://www.aphis.usda.gov/animal-care.
Advances in alternatives such as organ-on-a-chip models, computer simulations, and cell-based assays aim to reduce reliance on live animals, including cats, in future studies. Regulatory guidance from the FDA and international bodies increasingly encourages validation of non-animal methods where scientifically feasible https://www.fda.gov/regulatory-information/search-fda-guidance-documents.
