🐀 Vet’s 2025 Guide to Pet Rat Care: Enrichment, Nutrition & Health for Smart Companions 🧠🍎🏡

By Dr. Duncan Houston, BVSc

Rats are among the most intelligent and affectionate of all small pets. Often misunderstood, they are clean, highly social, and thrive on companionship and mental stimulation. This 2025 veterinary guide covers all you need to know about providing top-tier care for your pet rats—from housing and nutrition to behavior and health. 🐾

📖 Rat Basics

Pet rats (Rattus norvegicus domestica) typically live 2–3 years and require daily interaction. They are extremely social and must be housed in pairs or groups of the same sex to avoid isolation-related stress. Their intelligence makes them highly trainable and curious—perfect for active, attentive owners. 🐀

🏠 Housing & Environment

• Minimum Space: A multi-level cage measuring at least 80x50x80 cm for two rats; larger is better.
• Bar Spacing: Less than 1.5 cm to prevent escape.
• Substrate: Use paper-based or aspen bedding. Avoid pine or cedar—these can irritate the respiratory system.
• Enrichment: Include hammocks, ropes, chew toys, and climbing platforms.
• Hiding Spots: Rats love security—provide boxes, tunnels, and fleece pouches.

🍎 Diet & Feeding

Rats are omnivores, and a balanced diet is crucial:

• Pellets: Use a commercial rat block or lab block with 14–16% protein and 4–5% fat.
• Fresh Foods: Supplement with leafy greens, sweet potatoes, peas, apples (no seeds), and cooked grains.
• Proteins: Offer small portions of cooked chicken, boiled eggs, or tofu once or twice weekly.
• Water: Clean, fresh water should always be available—preferably in a sipper bottle.

⛔ Foods to Avoid

• Citrus fruits (for males): May affect kidney health.
• Blue cheese, chocolate, caffeine: Toxic to rats.
• Onions, garlic, raw sweet potato: Irritating or toxic.

🧠 Behavior & Training

Rats are brilliant and trainable! You can teach them to come when called, use a litter box, and perform tricks. Use positive reinforcement—small food treats and praise work wonders.

• Clicker Training: Rats quickly associate the sound with rewards.
• Target Games: Teach them to touch or follow a target stick.
• Maze Play: Great mental stimulation and bonding activity.

🚽 Litter Training

Rats naturally choose corners to eliminate. Place litter trays in these areas and add some soiled bedding to reinforce location. Use paper-based litter and clean trays daily.

🩺 Health & Veterinary Care

Rats are prone to a few common health issues. Regular checks and prompt veterinary care are essential:

• Respiratory Infections: Sneezing, wheezing, and porphyrin staining (red discharge around eyes/nose) are early signs.
• Mammary Tumors: Common in females—early spaying may reduce risk.
• Skin Parasites: Mites and lice may cause itching or hair loss.
• Dental Issues: Overgrown teeth must be monitored—provide chew toys and hard foods.

🧽 Cleaning & Hygiene

• Spot Clean: Daily removal of soiled bedding and uneaten fresh foods.
• Full Clean: Weekly deep clean of the cage and accessories with pet-safe disinfectants.

🎯 Enrichment Essentials

• Cardboard mazes and boxes
• Hanging toys and climbing ropes
• Dig boxes with shredded paper or clean soil
• Treat puzzles and foraging activities

💡 Tips for Bonding

• Spend time holding and gently petting your rats daily.
• Let them free-roam in a rat-proofed room under supervision.
• Use soft blankets, pouches, and lap-time to create positive associations.

🚨 When to See a Vet

• Changes in appetite or weight
• Persistent sneezing or labored breathing
• Lumps, especially along the abdomen or underarms
