How do you make tunnels for rats? - briefly
Use PVC or flexible cardboard tubing, cut to the required length, drill entry and exit openings, and secure with zip ties or tape inside the enclosure. Provide bedding at both ends and clean regularly to prevent odor buildup.
How do you make tunnels for rats? - in detail
Constructing safe passageways for laboratory or pet rodents requires attention to size, ventilation, and durability. Dimensions should allow free movement without crowding; a tunnel interior of 3–4 cm in diameter accommodates most adult rats comfortably. Length can vary according to enclosure size, but each segment should be no longer than 30 cm to prevent sagging.
Materials commonly employed include PVC pipe, acrylic tubing, untreated wood, and sturdy cardboard. PVC offers rigidity and easy cleaning; acrylic provides transparency for observation; untreated wood mimics natural burrows but demands regular inspection for splinters; thick cardboard is inexpensive and suitable for temporary setups. All components must be free of toxic coatings, sharp edges, and loose fibers.
Step‑by‑step construction:
- Measure the intended route and cut each tube or board to the required length, allowing a 1 cm overlap for connectors.
- Create junctions using elbow fittings, T‑connectors, or drilled holes, securing them with non‑reactive silicone sealant or zip ties.
- Insert a flexible ventilation mesh at regular intervals (every 10–15 cm) to maintain airflow while preventing escape.
- Attach the tunnel network to the enclosure walls or floor using brackets or adhesive pads, ensuring a stable, leak‑free connection.
- Test the assembly by running a hand through the passage; adjust any bends or gaps that impede movement.
Maintenance considerations include weekly cleaning with mild soap and water, thorough drying to avoid mold, and inspection for wear or damage. Replace any compromised sections promptly to preserve the health of the occupants. Regularly rotate the layout to provide environmental enrichment and stimulate natural exploratory behavior.
