How we calculate it

The minimums follow widely used rescue and welfare guidance: about 7.5 square feet for one or two guinea pigs, 10.5 for three and 13 for four, with more recommended. Boars usually get along better with extra room, so we add a column of grids for male groups. Each C&C grid is about 14 inches square.

Floor space matters more than height. Lofts and levels are extras, not a replacement for running room. Read our complete cage setup guide or the C&C build guide next.
