Which type of bedding is commonly used in mouse housing in general, including postoperative settings?

• A. Paper bedding material
• B. Sand
• C. Styrofoam beads
• D. Metal shavings

Answer: (A)

Bedding for mice focuses on safety, cleanliness, and comfort, with special emphasis on minimizing irritation around wounds during recovery. Paper bedding is favored because it is highly absorbent and soft, helping keep the environment drier and reducing moisture around an incision, which supports healing and lowers infection risk. Its low dust content makes it gentler on the respiratory tract and easier to monitor the animal’s condition, while its inert, non-irritating texture reduces skin and paw irritation. It’s also practical to replace during postoperative care, aiding in keeping the wound clean and visible.

Other materials pose problems. Sand is dusty and abrasive, which can irritate the respiratory system and skin. Styrofoam beads can be chewed or inhaled and may cause blockages or other health issues. Metal shavings are hazardous, capable of causing injuries and ingestion problems.
