How can you make a tunnel for a rat? - briefly
Use a flexible PVC pipe or cardboard tube cut to the needed length, seal one end, attach the other end to a stable base, and line the interior with bedding or a small ramp to allow the rodent to enter and exit safely.
How can you make a tunnel for a rat? - in detail
Creating a functional passage for a small rodent requires planning, appropriate materials, and attention to safety. Begin by measuring the intended length and diameter; a tunnel 2–3 cm wide and 20–30 cm long accommodates most laboratory or pet rats comfortably. Select a rigid yet lightweight substrate such as PVC pipe, acrylic tube, or cardboard rolled into a cylinder. Ensure the material is non‑toxic and easy to clean.
- Cutting and shaping – Use a fine‑toothed saw or utility knife to cut the tube to the desired length. Sand the cut edges to eliminate sharp fragments that could injure the animal.
- Ventilation – Drill several small holes (approximately 3 mm) evenly spaced around the tunnel’s circumference to provide airflow while preventing escape.
- Entrance and exit – Fit each end with a removable cap or a short piece of mesh secured with zip ties. Mesh openings should be no larger than 4 mm to keep the rodent inside while allowing visual inspection.
- Stabilization – Attach a base made of acrylic or wood to prevent tipping. Use brackets or silicone adhesive to secure the tunnel upright.
- Cleaning – Line the interior with a thin, washable fabric or place a removable tray at the bottom. This simplifies waste removal and reduces odor buildup.
After assembly, inspect the structure for gaps, loose components, or sharp edges. Place the tunnel in the animal’s enclosure, ensuring it does not obstruct other equipment. Monitor the rodent’s interaction for signs of stress or injury, adjusting the tunnel’s position or dimensions as needed. Regularly disinfect the passage with a mild, rodent‑safe sanitizer to maintain hygiene.
