How do you create tunnels for a rat? - briefly
Use PVC pipe, cardboard tubing, or flexible plastic conduit cut to the required length, join sections with connectors or tape, and anchor the structure to the cage walls. Place the completed passage at floor level, ensuring smooth interior surfaces for safe rodent navigation.
How do you create tunnels for a rat? - in detail
Creating functional tunnels for a rat requires careful planning, appropriate materials, and precise construction techniques. The process can be divided into three stages: design, preparation, and assembly.
The design stage defines dimensions and layout. Typical tunnel diameter ranges from 5 cm to 8 cm, allowing free movement while preventing escape. Lengths of 30 cm to 100 cm suit most laboratory enclosures. Incorporate bends of 90° or 45° to simulate natural burrows and to increase structural complexity. Include access points at both ends for cleaning and observation.
Preparation involves selecting materials that are durable, non‑toxic, and easy to sterilize. Common choices are:
- Polycarbonate sheets, thickness 3 mm, resistant to impact and autoclavable.
- PVC pipe, inner diameter 6 cm, wall thickness 2 mm, easy to cut and join.
- Acrylic rods, for transparent sections that facilitate visual monitoring.
Cut each component to the predetermined dimensions. For PVC, use a fine‑toothed saw to avoid burrs. Smooth all edges with sandpaper to prevent injury.
Assembly follows a systematic sequence:
- Fit connectors (elbows, tees) to the ends of straight sections, ensuring a snug press‑fit or using non‑reactive adhesive such as silicone sealant.
- Secure joints with clamps or zip ties while the adhesive cures.
- Test each segment for airflow and structural integrity by applying gentle pressure along the length.
- Install the completed tunnel system inside the cage, anchoring it to the base with brackets or weighted clips to prevent displacement.
Final verification includes checking for gaps, sharp edges, and any materials that could release harmful substances. Regular maintenance requires disassembly, thorough cleaning with mild detergent, rinsing, and sterilization before reassembly.
