🐀 The Vet’s 2025 Guide to Building the Ultimate Rat Cage Setup 🛠️

By Dr Duncan Houston BVSc – veterinarian & Ask A Vet founder. A well-designed cage isn't just a shelter—it's a sanctuary where rats explore, socialize, climb, forage, and thrive. In this 2025 guide, we break down how to create the ultimate habitat that’s clean, safe, mentally stimulating, and medically beneficial for your rattie crew. 🧼💚

📏 1. Choose the Right Cage Size & Layout

• 🐭 Minimum: 2×2×2 ft per pair, with at least 3 cubic feet per rat
• 📏 Multi-level: Add shelves, ramps, and hammocks to encourage exercise and mimic vertical exploration
• 💨 Wire bars allow ventilation, while deep plastic bases contain bedding and waste
• 🛡️ Bar spacing & sturdiness: Max ½ inch spacing to prevent escape; no sharp edges

🧼 2. Easy to Clean = Healthier Rats

• 🪣 Deep plastic tray base: Contains bedding and mess
• 🚽 Litter box training: Place in corner with soiled bedding to encourage use
• 🧽 Clean weekly: Full cage wash with pet-safe soap or vinegar solution
• 💧 Daily: Spot clean surfaces, refill water, remove food scraps

🍽️ 3. Safe Feeding & Watering Zones

• 💧 Use bottle with metal sipper; mount securely to prevent leaks
• 🍲 Food dishes should be heavy (ceramic) or attachable to prevent flipping
• 🥦 Feed pelleted diets + occasional fruits, veggies, and seeds
• 🚫 Avoid scatter feeding inside bedding—it attracts mold and pests

🎯 4. Enrichment Essentials

Happy rats are active rats! Provide:

• 🪵 Chew toys: Wooden blocks, cardboard, bird toys
• 🏗️ Climbing tools: Ladders, ropes, hammocks, hanging tubes
• 🧺 Digging stations: Fill boxes with safe paper bedding or hay
• 🧠 Puzzle feeders: Foraging wheels or treat balls engage problem-solving
• 🔁 Rotate toys every 1–2 weeks to prevent boredom

🛏️ 5. Comfy Hideouts & Beds

• 🛋️ Hammocks: Fleece or washable cotton; elevated to simulate canopy cover
• 🏕️ Hides: Plastic igloos, nesting boxes, or snuggle sacks
• 🌡️ Position away from drafty or sunny spots
• 🧺 Add shredded paper or fleece strips for nesting material

💡 6. Budget-Friendly DIY Upgrades

• 🧻 Use tissue boxes, toilet roll tunnels, and cardboard mazes
• 🪜 Convert old ladders, baby toys, or plastic shelves into climbing zones
• 🪴 For the adventurous: set up a bioactive enclosure with diggable substrate, springtails & coco husk

🛑 7. What to Avoid in Rat Cages

• 🪵 Cedar or pine shavings: Release respiratory-irritating phenols
• 📏 Gaps >½ inch: Can lead to escape or injury
• 💦 Leaky water bottles: Encourage mold & foot infections
• 🚫 Wire floors: Cause bumblefoot (ulcers); cover with fleece or solid platforms

✅ Routine Cage Maintenance Checklist

• 🧽 Daily: Clean food/water areas, remove poop and wet bedding
• 🧺 Weekly: Swap and launder fleece liners, clean tray and walls
• 🔁 Monthly: Rotate enrichment layout and inspect for broken or unsafe items
