A C&C Cage (aka Cubes & Coroplast) is a easy to build, customize, clean, and secure cage most recommended for guinea pigs. Pet store cages commonly marketed for guinea pigs and rabbits are essentially glorified litter boxes that aren't even suitable for one pig let alone two. C&C cages allow for more space while still containing all your pigs bedding (plus the pigs themselves!). Plus, these cages are highly customizable, so its a win-win!
