1 What is a fleece cage liner?
What is a fleece cage liner and how does it work?
A fleece cage liner consists of at least 2 layers, and most commonly 3 layers.
The top layer is fleece, which essentially offers a dry layer for your guinea pigs to live on.
Fleece does not hold moisture, so any pee will soak straight through and be ‘trapped’ in the absorbent layer underneath.

What is the absorbent layer?
Underneath the fleece layer you need an absorbent layer to soak up moisture.
Common absorbent layers include Zorb (more common in the US), U-haul blankets (also US), mattress protectors (100% cotton for absorbency), old bath/beach towels, or disposable options such as puppy pads/incontinence pads or newspapers.
In many cases the absorbent layer will be sandwiched between 2 layers of fleece to help keep the bottom of the cage dry, by trapping any moisture in the middle.
Whilst a third layer is not essential, it does mean you can use different patterns or colours on the top and bottom, and then essentially have 2 different cage liners in one. It can also offer some protection for the bottom of your cage.
Does a fleece liner need to have a waterproof layer?
It is also possible to have a waterproof bottom layer using a mattress protector (incontinence bedding) or other waterproof fabric such as PUL.
My limited personal experiences is that these are not as effective and tend to smell more quickly, and of course you can’t use both sides as the waterproof layer always needs to be on the bottom.
However, if you cage liner is directly on a surface that needs to be protected (wood, carpet, etc.) this can be a good option. If you do not want a liner with a waterproof layer, then it is possible to achieve the same level of protection by putting a waterproof layer (such as a shower curtain) directly underneath your normal fleece liner.
2 Getting started with fleece
How many liners will I need?
You will need at least 2, to allow for one in the wash and one in the cage.
If you have multiple cages you will need at least one liner for each cage and a couple of spares.
Buying ready-made liners
The easiest way to start using fleece bedding for your guinea pigs is to buy ready-made liners.

Sewing your own liners
A good option if you have a sewing machine (or a friend with a sewing machine) is to sew your own liners.
This allows you to customise them for your cage size, and can offer a cheaper alternative to buying commercial liners.
A good video explaining how to make your own liners and how they work can be seen here:

In the video she uses a waterproof bottom layer, but this could easily be replaced with fleece if you prefer.

A YouTube search will also bring up a host of suggestions for making all types of fleecy cage accessories for guinea pigs.
Creating a simple test liner or temporary set up
The cheapest way to try fleece (maybe before investing in expensive pre-made liners) would be to buy a piece of fleece or a fleece blanket, place an absorbent layer underneath, lay the blanket over the top, and see how this works for you and your piggies.
A well illustrated example of this set up can be seen on this thread:
