How can you create a second level in a rat’s cage? - briefly

Build a secure platform from metal mesh or untreated wood, fasten it to the cage walls with brackets, and attach a ladder or ramp for the rats to reach the upper tier. Verify that the structure leaves sufficient gaps for ventilation and prevents any possibility of escape.

How can you create a second level in a rat’s cage? - in detail

Creating a two‑tier enclosure for rats involves planning, material selection, and precise assembly. Follow these steps to ensure safety, durability, and enrichment.

1. Determine dimensions

   • Height: minimum 12 inches per tier, allowing comfortable standing and climbing.
   • Length and width: match the base cage size, leaving at least 1 inch clearance on all sides for airflow.
   • Weight capacity: each platform should support at least 2 lb per rat, plus accessories.

2. Select materials

   • Frame: stainless‑steel or coated aluminum rods, ¼‑inch diameter, for corrosion resistance.
   • Platform: solid, non‑treated wood (e.g., birch plywood) or safe acrylic sheet, thickness ¼ inch or greater.
   • Fasteners: stainless‑steel screws and nuts, lock washers to prevent loosening.
   • Supports: L‑shaped brackets or custom brackets welded to the cage walls.

3. Design support structure

   • Attach brackets to the interior walls at equal intervals, ensuring level alignment.
   • Use a drill to create pilot holes in the platform material, then secure with screws through the brackets.
   • Verify that the platform sits flat, with no wobble.

4. Integrate access points

   • Cut a 2‑inch opening in the side wall of the lower tier, install a removable acrylic door with a latch for cleaning.
   • Provide a small ramp or ladder: secure a ½‑inch thick wooden or PVC ramp at a gentle 30‑degree angle, anchored to both tiers.

5. Ensure ventilation and hygiene

   • Leave at least ¼‑inch gaps between platform edges and cage walls for air flow.
   • Use removable platform panels for easy cleaning; avoid porous surfaces that retain moisture.

6. Add enrichment

   • Attach chew‑safe toys, hammocks, or hide‑outs to the upper tier using zip ties or small brackets.
   • Place bedding on both levels, ensuring the upper layer is thin enough to prevent collapse.

7. Test stability

   • Apply gradual weight to each tier, checking for flex or shifting.
   • Adjust screws and brackets as needed before introducing the animals.

By adhering to these specifications, the resulting multi‑level cage will provide a safe, stimulating environment while simplifying maintenance and preserving structural integrity.
