Providing the best, compassionate care for NPRC animals is a top priority and helps ensure research results are scientifically valid. NPRC staff monitors animals daily in order to quickly address any concerns, and all animals receive comprehensive annual checkups, much like humans. The NPRCs follow regulations and guidelines established by the NIH, the USDA via the Animal Welfare Act and institutional animal care and use committees. In addition, all NPRCs maintain AAALAC Int. accreditation, the gold standard in animal care.
