What is best to line a rat’s cage with? - briefly
A thick, low‑dust paper bedding (e.g., aspen shavings or commercial rodent substrate) placed over a removable, washable plastic tray provides the most suitable lining. Cedar or pine should be avoided because their aromatic oils can irritate a rat’s respiratory system.

Choosing the appropriate substrate for a rodent enclosure is essential for health, hygiene, and comfort. Several materials meet these criteria, each with distinct advantages and limitations.
Absorbent, low‑dust bedding such as paper‑based cellulose pellets provides excellent moisture control and minimizes respiratory irritation. Pellets can be broken down for nesting material, and they decompose quickly for easy cleaning.
Wood‑shaved products, specifically kiln‑dried Aspen or Pine, offer softness and good absorbency. Aspen lacks aromatic oils that can harm rodents, while pine retains resin that may cause respiratory issues; therefore, only kiln‑dried, low‑resin varieties should be considered.
Corncob bedding is inexpensive and highly absorbent but generates considerable dust and can become moldy if not changed frequently.
Reusable options like hemp or recycled paper mats reduce waste and can be washed, though they require thorough drying to prevent bacterial growth.
For cages with a solid floor, a thin layer of non‑adhesive, non‑toxic fleece can serve as a comfortable base, provided it is cleaned daily to avoid accumulation of waste and moisture.
When selecting a lining material, evaluate the following factors:
- Absorbency rate (grams of liquid per gram of substrate)
- Dust production (mg per cubic meter)
- Potential allergens or toxins
- Cost per square foot and availability
- Ease of removal and disposal or cleaning
In practice, a combination of cellulose pellets for daily use and a thin fleece liner for the bottom of a solid‑floor cage offers balanced moisture management, low respiratory risk, and comfortable footing. Regular spot‑cleaning and complete substrate replacement weekly maintain optimal sanitation and prevent odor buildup.
