How can you build a house for rats? - briefly
Use a compact wooden frame lined with soft bedding, incorporate PVC tunnels and a sealed lid for security, and provide separate nesting and feeding zones. Choose untreated pine, non‑toxic glue, and washable fabrics to keep the structure safe and easy to maintain.
How can you build a house for rats? - in detail
Construct a compact shelter that meets the physiological and behavioral needs of laboratory‑grade rats. Begin with a rigid frame made from untreated pine or PVC pipe; dimensions of 30 cm × 20 cm × 20 cm provide sufficient space for a small colony while limiting excessive movement that could cause injury. Secure joints with non‑reactive epoxy or stainless‑steel screws to prevent rust and contamination.
Select a base material that is easy to clean and resistant to gnawing. High‑density polyethylene (HDPE) sheets, 3 mm thick, serve as an ideal floor. Attach the sheet to the frame using silicone sealant, creating a watertight seal that prevents moisture accumulation. For walls, use wire mesh with 1‑mm openings, encased in a thin layer of acrylic sheet to protect against escape while allowing airflow.
Install a ventilation system that maintains air exchange without creating drafts. Position two 2‑cm diameter holes opposite each other near the top of the structure; cover each opening with a fine nylon filter to block dust and pathogens. Connect the holes to a low‑velocity fan that circulates air at 0.5 m³ min⁻¹, ensuring temperature stability between 20 °C and 24 °C.
Provide nesting material and enrichment within the interior. Place a 5 cm layer of shredded paper or aspen shavings on the floor, and attach a wooden chew block to one wall. Secure a small plastic tunnel (10 cm long) to simulate burrowing behavior; anchor it with silicone to avoid displacement.
Implement a cleaning protocol. Flush the interior with warm water, then apply a 0.5 % hydrogen peroxide solution for disinfection. Rinse thoroughly and allow complete drying before re‑introducing the rodents. Replace nesting material weekly to maintain hygiene.
Summarize the essential components: sturdy frame, impermeable floor, ventilated mesh walls, controlled airflow, enrichment items, and a rigorous sanitation routine. Adhering to these specifications yields a functional, safe dwelling that supports normal growth and reduces stress in the animal population.
