C&C Cages for Guinea Pigs

C&C cages are very popular with guinea pig owners who wish to house their pets indoors. In fact, they were designed with cavies in mind.

This type of housing is also the best option if you have more than 2 guinea pigs as they can be built the exact size that is required for your cavy family.

In this article, we give you all the information you need about these cages including the links to where you can buy a full C&C cage kit or individual components for a more custom design. If you'd like to go straight to the place where you can buy them, you can check the prices out here on Amazon

What is a C&C Cage?

C&C cages are modular guinea pig cages that are usually built to be open and spacious.

They consist of panels / grids which you connect together with C&C connectors and cable ties with a Coroplast (plastic sheeting) insert. 

Usually they are open cages which means it is easy to access your pets for extra cuddles and makes cleaning fairly easy. 

Benefits of a C&C Guinea Pig Cage

One of the main advantages of the C&C guinea pig cage is that it is extremely versatile in design. 

You can build whatever size cage you need and you can even create a second smaller tier over the top. This means more space for your guinea pigs with the added advantage that it doesn’t take up any more floor space in your home.

We use this type of cage for our guinea pigs which fits perfectly into the large space under our stairs.

How Easy is it to Build a C&C Cage?

You will need to plan out the configuration of the cage before you start. If you are only having one tier, it is relatively simple. However, if you are adding a second tier it becomes a little more challenging.

The most difficult part of building a C&C cage is cutting the coroplast in the right shape and making sure it fits correctly.

C&C Cage Supplies

You can buy a C&C Cage as a complete kit or you can purchase the various bits and pieces for the specific size you require.

Which C&C Cages are the Best?

We only recommend the C&C cages sold by Grendle on Amazon. We believe these are the best C&C cages available in the UK.

They are safe for the majority guinea pigs and have the right spacing between bars (approx 3.5cm) to ensure your pets aren't in danger of escaping or getting stuck in the bars. However, if you have baby guinea pigs or breeds with narrower heads than most, you may need to double check that they are going to be safe.

Grendle also sells all the accessories needed if you are building a bespoke cage or if you need extras, except for the coroplast insert which you will need to buy separately.

Read on for the links to all the kits and components.

Buying a Complete C&C Cages Kit

C&C Cages Kit

C&C Cage Kit - Available in various configurations and sizes

The complete C&C Cage Kit is available in a range of sizes including 4x2, 5x2, 6x2 and those same sizes with a 1x2 loft. Please note that these are the number of grids and not measurements in feet or cm. They also sell a 3x2 but we don't recommend this as it is below the recommended size for guinea pig housing. 

What Size Cage Do I Need?

The size of cage that you need obviously depends on how many guinea pigs you have. Here are the C&C Cage Kit sizes that are available for purchase together with the recommended number of guinea pigs for that particular space:

  • 3x2 grids - 43 x 28 inches / 109 x 71cm (not recommended)
  • 4x2 grids - 57.5 x 28 inches / 146 x 71cm (2-3 guinea pigs)
  • 5x2 grids - 71.5 x 28  inches/ 182 x 71cm (2-4 guinea pigs)
  • 6x2 grids - 85.5 x 28 inches / 218 x 71cm (2-5 guinea pigs
  • 1x2 grid loft measures 14 x 28 inches / 36.5 x 71cm (this makes an excellent cosy sleeping area)

We have 6 guinea pigs with a 5x2 grid but with the addition of a 3x2 loft separated into a 2x2 feeding area and a 1x2 dark sleeping area. We have custom built this by purchasing the grids etc separately.

I would certainly not have anymore piggies in this space as it would be too much, but they are all very happy and contented with lots of popcorning and happy squeaks so this size seems to suit them.

As these kits don't include the coroplast you will need to buy this separately. Take a look here at coroplast information and buying options.

Buying Individual Components

If you want to build your own C&C Cage as we did, you will need to buy the various components separately.

These are the items you will need to purchase to build your guinea pigs C&C cage:

C&C Cage Grids

You must be very careful when buying these grids. There are some for sale which aren't suitable for guinea pigs because of the large bar spacing. This means that they may be able to escape or they could hurt themselves by getting stuck.

There have been incidents of strangulation when guinea pigs have got their heads stuck between the bars. If you choose to buy your cage somewhere other than those recommended here, please do check they are 9x9 grids measuring 14x14 inches.

There have also been some inferior ones on the market with a particular type of plastic coating that is not safe for guinea pigs. The ones we recommend are the ones that we use for our cavies and we know to be safe.

The panel pictured below is the one that is safe for guinea pigs.

C&C Connectors

These are the small round plastic connectors (8-way) that you clip on to the corners of the grids to make the cage. Some people ask if they can just use cable ties but you really do need these connectors to do a proper job. They’re very easy to fit too.

Cable Ties

You will need cable ties in addition to the connectors to make the cage nice and sturdy.

They are also useful to use as hinges if you want to create opening doors with any of the grids or grid sections.

Check the price of cable ties on Amazon.


Coroplast is the plastic sheeting that goes inside the cage.

It is a water-resistant plastic polypropylene fluted display board often used for making signs but works brilliantly in these modular cages as it is flexible and can be cut to size fairly easily.  

Coloured Sheets of Coroplast
Coroplast comes in sheets that you can cut to size.

You will need to buy the A1 size (594mm x 841mm) and will most likely need more than one sheet. These particular ones come in packs of 3 in a range of colours (white, black, red, green, yellow) and you can either order the individual colours or buy a mixed set.

C&C Cage Liners

Most guinea pig owners who have C&C housing use fleece cage liners.  This is the best option as you may have the odd sharp bit from the cable ties that stick out from the coroplast which need to be covered.

We made our own cage liners but they do take some time and effort to make and you'll need a sewing machine to do it properly so it is a lot easier to buy them ready-made.

These are available from sellers in the UK and also in the US so wherever you are based you will find someone who will be able to make them for you at a very reasonable price.

Cage Safety

If you don’t have other pets in the home, your C&C cage can be left open at the top. If you have other animals such as cats then you should either use a traditional cage or make your C&C cage safe by build tops for them. Bear in mind when designing your cage that you will need to have easy access for cleaning it out regularly.
