Why is bedding choice critical for small animals?

Prof. Edward Clarke, Ph.D.Quality bedding systems have a direct impact on the respiratory health and comfort of small animals. Poorly chosen substrates release toxins that are damaging to the lungs over time. The right substrates enable natural behaviors, such as burrowing and odor control. Your bedding selection will not only prevent chronic disease but also promote species-specific behaviours.
Risks from toxic bedding* are found in cedar and pine shavings. These release phenol compounds that attack liver enzymes. Within weeks, rodents develop breathing difficulties. Clay litters bunch together when wet, and if ingested, may cause intestinal blockage. Always check the safety of the material before purchase.
Aspen Shavings
- Safe for all rodents and rabbits
- Medium absorbency controls moisture
- Discourages bacterial growth
- Replace every 5-7 days
Paper-Based Bedding
- Highly absorbent for urine control
- Dust-free option for sensitive species
- Biodegradable and eco-friendly
- Change twice weekly
Fleece Liners
- Reusable system for guinea pigs
- Wick moisture away from surface
- Machine washable at 140°F (60°C)
- Spot clean daily, wash weekly
Depth requirements vary significantly between species. Burrowers like hamsters need 6-8 inches (15-20 cm) for tunneling. Non-burrowers like chinchillas require only 1-2 inches (2.5-5 cm). Incorrect depth causes stress and abnormal behaviors.
Odor control methods preserve habitat freshness. Layers of baking soda beneath the bedding neutralize ammonia. Activated carbon filters can absorb a wide range of gases. Solutions of white vinegar disinfect during habitat changes. These methods help provide a healthier habitat between scheduled full cleanings.
Use suitable bedding right away if poorly bedding was used. Transition over 3 days. Mix some new bedding into the old bedding. You will notice more activity and better respiratory function after about a week.
