* Potential for ink and chemicals: Paper bags often contain inks and glues that can be toxic to guinea pigs if ingested. Even if you can't see ink, there might be trace amounts that can be harmful.
* Dust: Shredded paper bags can generate dust, which can irritate your guinea pig's respiratory system.
* Lack of absorbency: Paper bags are not very absorbent, so they won't be good at soaking up urine and feces, leading to a messy cage and potential health issues.
* Not ideal for burrowing: Guinea pigs love to burrow, and paper bags don't provide a good substrate for this natural behavior.
Better Bedding Options:
* Aspen shavings: A popular and affordable choice, but some guinea pigs can be sensitive to the dust.
* Timothy hay: Great for bedding and a source of fiber for your guinea pig.
* Paper-based bedding: Look for products specifically designed for small animals, which are made from recycled paper and are generally safe and dust-free.
* Fleece liners: Reusable, washable, and very absorbent, but you'll need to change them frequently and provide additional hay for bedding.
Always consult your veterinarian before making any changes to your guinea pig's environment. They can help you determine the best bedding for your specific pet's needs.
