Cubes & Coroplast Cage

Contributed by Wendy Lee


We recommend building a C & C (Cubes & Coroplast) cage for your guinea pigs to live in. The recommended size, reasons and tutorial on how to build a C & C cage can be found below.


Recommended Cage Size

No of pigsRecommended areaMeasurements in cm
10.7 m² or more76cm x 91cm
21 m² or more76cm x 127cm
31.2 m² or more76cm x 157cm
41.2 m² or more76cm x 193cm

*These are recommended measurements and not cast in stone. You may need to increase your cage size accordingly depending on the interactions of your guinea pigs while they are inside. Information taken from Guinea Pigs Cage Store

A C & C cage is recommended because:

  • It is inexpensive as compared to store-bought cages. I have put together a 120cm x 65cm cage for my two girls for less than SGD 100 and it is still in use even until today, 2 years later!
  • It is easy to expand and collapse depending on your needs. If you happen to adopt more guinea pigs, you can always buy more grids to add on to the current cage.
  • It maximises space for your guinea pigs to exercise. Watch them run races or laps in your cage when there is enough room! This is essential especially when you are unable to provide them with daily floor time (allowing them to roam freely in an open space in your house)
  • It helps to prevent fights. A bigger cage is essential when you have more than one guinea pig as it allows guinea pigs to play with one another as well as to escape from one another when they want to
  •  It prevents the pee and poo from becoming too concentrated on one spot
  • It can be modified easily (by adding additional grids on top of the cage) to become cat-proof/dog-proof for owners who also have cats and/or dogs at home
  • It has good ventilation and air circulation which are important to prevent URI (Upper Respiratory Infection), a very common illness which can be fatal to guinea pigs
  • It allows you to monitor your guinea pigs easily as the grids provide good visibility
  • It fits easily on tables or you can also add grids below to form storage space for your ever-growing guinea pig’s supplies

How to DIY a C&C cage

Arrange all the grids and secure them with cable ties.

Place in the bath mats.

Cut out the coroplast piece according to the measurement. Be as accurate as possible as wrong measurement will cause the tray to be stuck.

Using pen knife, lightly ‘score’ the coroplast to form a line so it is easy to fold up along the line. Be careful not to cut through the coroplast!

Secure the corners using duct tape.

The tray is done!

Slot the tray underneath the cage. Notice the front of the cage is shorter than the sides and the back so as to allow the tray to go in.
