Guinea pig owners routinely utilize wood or paper types of shavings as the bedding for their pets. While this is perfectly acceptable if the proper sort is chosen, namely those not made of sawdust, cedar or pine, there may be better choices available.
Guinea pigs that inhale tiny bits of paper, dust or wood may ultimately develop respiratory issues or have eye sensitivity. Because wood-type shavings or paper-based products can be shuffled around easily within the cage, the end result is not terribly sanitary.
The pig will end up rolling around in waste until the cage is thoroughly cleaned. While paper and wood shavings are extremely common, they are not environmentally friendly and can become costly as well.
