Practical guidelines for the species-adequate housing of guinea pigs in research facilities. Animals living in groups should be provided a floor area of no less than 1200 cm2 per breeding female, and no less then 750 cm2 per weaned, non-breeding animal. A box with an access hole makes the central area of the enclosure a place of refuge for the animals thereby improving their well-being and, at the same time, increasing the usable floor space.
