* Ingestion risk: Guinea pigs are known to chew on anything they can reach. Felt can be ingested, which could lead to digestive problems, blockages, or even death.
* Potential for fibers to detach: Felt can shed fibers, which could be ingested or cause respiratory problems.
* Difficult to clean: Felt can be difficult to clean and can harbor bacteria and parasites.
* Not as absorbent as other bedding: Felt doesn't absorb urine or moisture as effectively as other bedding materials, which can lead to a damp and unsanitary environment.
Safer alternatives:
* Aspen shavings: A popular choice for guinea pigs, aspen shavings are absorbent, dust-free, and relatively inexpensive.
* Paper bedding: Recycled paper bedding is another good option. Look for varieties that are soft, absorbent, and free of dyes and inks.
* Wood pellets: These pellets are absorbent and can help to control odor, but be sure to choose a variety that is safe for guinea pigs.
* Hemp bedding: This bedding is biodegradable, dust-free, and highly absorbent.
* Timothy hay: While not a bedding material, hay can be used as a base for bedding, as guinea pigs need to eat hay regularly.
Always consult with your veterinarian to determine the best bedding for your guinea pig.
