My favourite bedding choice for c&c cages is towels topped with fleece. You can buy these pre-made or you can simply place a large piece of fleece on top of some towels. However, you must treat the fleece first to remove it’s waterproof layer so that the urine can flow through to the absorbant layer (towels). The absorbant layer could also be made of anything absorbant such as puppy pads or simply newspaper (although newspaper often gets stuck once wet).
Treating the fleece is straightforward. You simply wash the fleece on a high temperature and tumble dry it several times. However, you need to be careful not to add fabric conditioner as this keeps the waterproof layer intact. To test whether your fleece is ready, place it on an absorbant layer and pour a small amount of water on it. If there is still a bubble of water on the top, it needs further treatment. If the water soaks through to the absorbant layer and the fleece dries out, it is ready. The process usually takes about 3 washes but can take as little as 1 cycle up to about 7 cycles.
