C&C Cage for Guinea Pigs: How to Build One Step by Step

How to build a C&C (cubes and coroplast) guinea pig cage: grid sizes, materials, layout and safety tips, plus a free size calculator.

What a C&C cage is

A C&C cage uses storage cube grids for walls and corrugated plastic (coroplast) for the base. It is popular because it is spacious, affordable and easy to resize.

What you need

  • Grid panels, usually about 14 inches square.
  • Connectors or cable ties.
  • A coroplast sheet cut and folded into a tray with sides around 6 inches high.
  • Bedding, hides, hay rack, bowls and water bottle.

Grid sizes at a glance

  • 2x3 grids: suitable for one pig only.
  • 2x4 grids: common size for two pigs.
  • 2x5 grids: comfortable for two, good for three.
  • 2x6 grids and up: three to four pigs or boar pairs.

Safety tips

  • Use baby-safe grids or smaller openings if you have young pigs who could squeeze through.
  • Add a lid if you have cats or dogs.
  • Keep the cage off cold floors and away from drafts.
