Which bedding types are bad and should not be used for rodents?

• A. Pine and Cedar
• B. Paper Product
• C. Straw
• D. Cotton batting

Answer: (A)

Beddings for rodents should minimize respiratory irritation and ingestion risk. Pine and cedar shavings release aromatic oils and dust that contain irritating compounds (phenols and terpenes) which can inflame the airways and stress the liver in small rodents. The dusty nature of these woods also worsens respiratory problems and can predispose to chronic breathing issues, so they’re not recommended.

Paper-based bedding is typically safe when it’s unscented and free of inks or additives, making it a common choice for rodent cages.

Straw can be used but tends to be dusty and prone to mold or contamination, which can irritate the respiratory tract or lead to allergies in some animals.

Cotton batting poses a higher risk because rodents may chew or swallow fibers, potentially causing choking or GI obstruction.

So the reason pine and cedar are the bad option is their toxic oils and dusty emissions that harm the animal’s respiratory and overall health.
