Guinea Pig Cages, Bigger is Better!


"C&C" stands for Cubes and Coroplast. We coined "C&C" 20 years ago when all the storage grids sold were branded as "Cubes." They form cubes when you snap them together for storage shelves. Coroplast is the brand name for 'corrugated plastic' which comprises the plastic, waterproof base that forms the box into which you add bedding, accessories, and your piggies. The wire grids (that form the cubes) are arranged around the perimeter of the cage, providing safety, airflow, visibility, and the potential of building up and out like tinker toys.

Why So Big?

Pet store-sized cages are glorified litter boxes. Does 7.5 square feet sound like a lot? It's not really. In the grander scheme of things, it is still a very small environment for your cavy. Exercise and exploration space are very important for their long-term health and happiness. Cavies need enough room to do "full-tilt laps." Upper levels should not be counted in providing the minimum square footage. In fact, ramps used to provide access to the upper deck usually take away from downstairs exercise space and count against square footage.

Health Benefits of a C&C Cage

Exercise in General

  • The health benefit of exercise for guinea pigs is significant. Like humans, overweight guinea pigs have a higher tendency toward health problems, including heart disease, diabetes, bladder infections, respiratory problems, bumblefoot, and more.
  • Adult males can develop a condition called impaction -- a loss of muscle tone in the anal area, causing their droppings to get 'backed up' and require periodic cleaning by their guardians. A large cage with ample room for exercise can help keep your guinea pig toned and fit.
  • Adult females tend to put on weight in their belly as they get older. It's more difficult to find and diagnose ovarian cysts and other related problems in females when they are overweight.

Exercise on Their Schedule

  • Not yours. Even if you provide an ample amount of floor time every day, your guinea pigs need to be able to exercise and explore on their own body clocks. Guinea pig activity tends to be an hour "on" and an hour "off." Many are particularly active in the morning and evening -- not necessarily at times that are convenient for you. If they have a large enough cage, they can exercise whenever they choose.


  • Like people, guinea pigs get bored living in the same old small cage hour after hour, day after day, year after year with nothing much to do. It would be like 'being sent to your room' forever, only your room is the size of a walk-in closet and that becomes your life. You have to entertain yourself, eat, sleep, and 'go to the bathroom' all in that small space -- until you die. Even if you are hauled out and allowed to 'play' with some other species periodically, it's a mind-numbing, dreary existence.

Keeping the Peace

  • If you have two or more non-breeding or same-sex guinea pigs (as you should, since they are social animals), it helps keep them happy with each other if they have enough room to run and play and to get away from each other when they choose.

Easier to Clean

  • Believe it or not, a larger cage is much easier to clean and keep clean than the smaller pet store or commercial cages. You can read other people's experiences in the Testimonials and find out more about how to clean the cage on the cleaning page. And an easier to clean cage for you means you'll love your guinea pigs that much more over the years.

More Fun for You

  • Happy guinea pigs are more entertaining and well-adjusted guinea pigs. Healthy guinea pigs means fewer vet visits, worries, and bills. Easy-to-maintain guinea pigs means a happier relationship with your animals. You'll spend less time cleaning and more time enjoying them and your life, especially knowing they are doing so well and you are doing the right thing by them.
