A block to progress in the design of cages and other restricted environments for animals has been the notion that animal and human needs are necessarily in conflict. The design process should list the established and suspected animal needs separately from human needs- husbandry and experimental. Comparison of the two lists will often show more compatible needs than expected, and design features can be worked out to fulfill them. Adjustments may be made where needs are less compatible until "sufficient" compatibility is achieved. An innovative design for a mouse cage is described to show that this process can lead to harmony, new observations on animal needs, and unforeseen benefits to both animals and humans.
