Wood shavings used to be popular, but more information on how they can harm pets has been discovered over the years, especially cedar shavings. Popular choices include fleece, which can be purchased from a craft store and then washed and reused when it gets dirty, and various kinds of paper-based small animal bedding. Warning It's essential to provide vitamin C in the guinea pig's diet as they can't produce it naturally. Also, avoid using cedar wood shavings as bedding, as it can harm your guinea pig. Feeding Vitamin C is crucial in a guinea pig’s diet, as they cannot produce it themselves, similar to humans and capybaras. Supply this vitamin through guinea pig-safe supplements and fortified pellet food. Additionally, provide plenty of roughage like timothy hay, and avoid sugary treats and seeds to prevent gastrointestinal problems.
