Reinhardt, V. 2004. Flaws in federal regulations pertaining to the welfare of primates kept in research institutions. Journal of Applied Animal Welfare Science 7(4), 273-276.

Federal welfare regulations for primates kept in research laboratories fail (1) to include recommendations pertaining to the legal requirement of the avoidance of stress and unnecessary discomfort during handling procedures, (2) to specify how the legally required uniform illumination can be achieved in the prevailing double-tier caging system, (3) to require sufficient space for caged primates to make social adjustments, (4) to define the ad hoc created term psychological well-being, but they (5) include the clause that the useless space beneath too low resting surfaces can be counted as part of the floor space.
