How can I add a second level to a rat cage? - briefly
Mount a sturdy platform using chew‑proof wood or metal slats secured to the cage walls with brackets, then attach a safe ladder or ramp for access and a secure lid to prevent escape. Regularly inspect all connections for wear and reinforce any loose points.
How can I add a second level to a rat cage? - in detail
Adding a second tier to a rodent enclosure improves space utilization and provides enrichment. Follow these steps to construct a safe and functional upper level.
Select a cage with sufficient footprint. A minimum base of 24 × 24 inches allows a sturdy platform without compromising floor space. Verify that the cage has a solid top bar or mesh that can support additional hardware.
Gather materials:
- 1/4‑inch plywood or untreated solid wood panel cut to fit inside the cage dimensions, leaving a ½‑inch clearance from the walls.
- 2‑inch stainless‑steel brackets or L‑shaped corner braces.
- ¼‑inch drill bit and screwdriver.
- Non‑toxic, water‑based paint or sealant (optional, for moisture protection).
- Small wooden or plastic ramps, or a series of graded steps.
- Cable ties or zip ties for temporary support during assembly.
Prepare the platform:
- Sand all edges of the wood to eliminate splinters.
- Apply a thin coat of sealant; allow to dry completely.
- Position the panel at the desired height, typically 6–8 inches above the floor, ensuring the rat can reach it comfortably.
Secure the platform:
- Align brackets with the cage’s side walls, spacing them every 4 inches.
- Drill pilot holes through the brackets into the cage’s metal or plastic frame.
- Tighten screws to create a rigid connection; avoid overtightening that could deform the cage material.
- If the cage uses a wire mesh top, attach brackets to the mesh using reinforced cable ties, then tighten until the platform is level.
Install access:
- Attach a 4‑inch wide ramp to the front or side of the platform, securing it with brackets or zip ties.
- Ensure the ramp’s angle does not exceed 30 degrees; a gentler slope reduces strain on the animal’s joints.
- Test stability by applying pressure to the ramp and platform; any wobble must be corrected before introducing the rats.
Safety checks:
- Verify that no sharp edges or protruding screws remain.
- Confirm that the platform does not block ventilation openings.
- Ensure the height does not impede the cage’s door operation.
Maintenance considerations:
- Choose a removable platform design; detach brackets or use quick‑release pins for cleaning.
- Place a thin layer of bedding on the upper level to prevent slipping.
- Rotate food and water bottles to prevent tipping on the new tier.
After installation, observe the rats for a few hours. Look for signs of hesitation or difficulty accessing the level. Adjust ramp angle or platform height if needed. The added tier should remain secure for the cage’s lifespan, providing additional climbing space and enrichment without compromising safety.
