How to make shelves for a rat cage? - briefly
Cut plywood or acrylic to the desired width, drill pilot holes, and secure with stainless‑steel brackets or L‑shaped supports screwed into the cage walls; add non‑slip pads or sandpaper on the surface for traction. Ensure all edges are sanded smooth and the mounting hardware is rust‑resistant to maintain a safe environment.
How to make shelves for a rat cage? - in detail
Creating functional levels inside a rodent enclosure requires precise planning, appropriate materials, and secure assembly. Begin by measuring the interior dimensions of the cage—width, depth, and height. Subtract a margin of 1–2 cm from each side to allow clearance for walls and any sliding doors. Determine the desired number of shelves; typical setups use two or three levels spaced 8–10 cm apart, providing ample room for climbing and nesting.
Select materials that resist gnawing and are easy to clean. Common choices include:
- Untreated pine or birch plywood, 6 mm thickness, sealed with a non‑toxic polyurethane.
- Acrylic sheets, 4 mm thick, cut with a laser cutter for precise edges.
- Metal brackets or L‑shaped steel supports, powder‑coated to prevent rust.
Cut each shelf to the calculated size, rounding corners to eliminate sharp edges. Drill pilot holes at each corner and along the edges, spacing them 2 cm apart, then insert stainless‑steel screws (3 mm diameter) to attach the brackets. Use a cordless drill with torque control to avoid over‑tightening, which could split the wood.
Mount the brackets on the cage walls. Align the first bracket set 2 cm below the top rail, ensuring a level surface with a bubble level. Secure with self‑drilling screws that penetrate the cage frame by at least 10 mm. Repeat the process for each subsequent shelf, maintaining equal vertical spacing.
After installation, test stability by applying gradual pressure to the edges of each level. If any flex is detected, add diagonal braces made from thin metal strips, fastened with small rivets. Finally, clean all surfaces with a dilute enzymatic cleaner, rinse thoroughly, and allow to dry completely before introducing the animals.
Regular inspection every two weeks should focus on wear at attachment points, signs of gnawing, and any loosened hardware. Replace compromised components promptly to preserve the safety of the occupants.
