Ultimate Rat Care Guide

Are you considering adding new pet rats to your family? There is so much to discover and learn about their care! Whether you are a first-time owner or an experienced handler, this guide will equip you with crucial, up-to-date information for keeping your companions healthy, active, and thriving.

Rats are highly social, intelligent animals and must be adopted in same-sex pairs or small groups (trios are ideal)!

🏡 Creating an Enriching Habitat

Designing a comfortable, stimulating environment is essential to your rats' physical and mental well-being.

1. Cage Space & Upgrades

Spacious Setup: Provide a large, wire cage with appropriate bar spacing (1/2 inch is recommended for young rats and females).

Maximizing Space with Deep Pans: Standard shallow cage trays don't allow for natural behaviors and spill bedding everywhere. We strongly recommend upgrading cages like the Double Critter Nation with deep stainless steel or heavy-duty plastic drop-in replacement pans (such as 8-inch-deep cement mixing tubs or custom metal pans). Replacing flat wire shelves with full-floor deep pans vastly increases usable floor space and prevents foot injuries like bumblefoot.

2. Burrowing & Bedding Fundamentals

The Need to Burrow: Rats have a strong natural instinct to dig, tunnel, and burrow. Providing a deep layer of bedding (at least 3 to 4+ inches in a deep pan) gives them necessary mental enrichment and stress relief.

Bedding Options:

Flake Pine / Aspen Shavings: Highly recommended for superior ammonia control. Note: Pine must be dust-extracted and kiln-dried.

Paper Bedding: Soft for nesting but requires frequent spot-cleaning as it does not control ammonia as effectively.

Fleece Liners: Great for shelf coverings, but fleece does not allow burrowing and offers zero ammonia control on its own unless paired with absorbency layers underneath.

DO NOT USE: Cedar bedding or scented litter, as the aromatic oils are toxic and cause severe respiratory illness.

3. Cozy Hides & Nesting

Provide multiple resting areas so every rat feels secure. Use large igloos, wooden hideouts, hammocks, sputniks/space pods, and cardboard boxes filled with tissue or soft paper materials.

4. Climbing & Vertical Space

Rats love to climb! Fill vertical space with ropes, cargo nets, bird ladders, lava ledges, and fabric hammocks. Hammocks also serve as "fall catches" to prevent injury in tall cages.

🌡️ Environment & Temperature Control

Rats are very sensitive to extreme temperatures and high humidity. Maintain a cage room temperature between 65°F–75°F (18°C–24°C) in a well-ventilated area away from direct sunlight and harsh drafts.

Emergency Temperature Management

Cooling Techniques (Hot Weather):

Relocate the Cage: Move the cage to a cooler room or basement.

Ice Packs: Wrap frozen ice packs or water bottles in thick socks/towels and place them in the cage.

Ceramic Tiles or Marble Slabs: Chill tiles in the fridge and place them in the cage for rats to lie on.

Pea Fishing: Offer a shallow dish of cool water filled with frozen peas for interactive cooling.

Heating Techniques (Cold Weather):

Warm Water Bottles: Place a bottle filled with warm water wrapped securely in a towel inside the cage.

Extra Nesting Material: Provide extra fleece scraps, shredded paper, or hay for burrowing.

External Heating Pads: If using a heating pad, place it on LOW under only one half of the cage exterior so rats can move away if they get too warm. Ensure all electrical cords are completely out of reach.

Avoid heat lamps or internal heat sources, as rats will chew cords or touch hot surfaces.

🥗 Nutrition & Water

• Base Diet: Feed a high-quality, nutritionally balanced commercial block or lab pellet formulated specifically for rats to prevent selective feeding.

• Fresh Foods & Treats: Supplement daily with fresh veggies (kale, broccoli, carrots, peas) and occasional fruits (apples, berries). Offer healthy proteins like cooked eggs, mealworms, or seed mixes in moderation.

• Hydration: Fresh drinking water should always be available via chew-proof glass or heavy-duty water bottles. Check nozzles daily to ensure they aren't blocked or leaking.

🧼 Hygiene & Cage Cleaning

• Spot Cleaning: Remove soiled bedding, leftover fresh food, and wipe down plastic surfaces every 1–2 days.

• Deep Cleaning: Perform a full bedding change and wash pans/accessories every 1–2 weeks (depending on group size).

• Safe Cleaners: Wash cage pans and toys using mild solutions like Dawn dish soap, white vinegar/water mix, or Chlorhexidine (2%). Rinse thoroughly and allow everything to dry completely before adding fresh bedding.

• Bathing Note: Rats are meticulous self-groomers and rarely need baths. Only bathe if they get excessively dirty or sticky, using a shallow basin of lukewarm water and a gentle, tear-free pet shampoo. Always dry them completely to prevent chills.

🐾 Enrichment, Bonding & Health

• Daily Playtime ("Out-of-Cage Time"): Rats require at least 1 hour of supervised free-roaming time daily in a rat-proofed area or playpen equipped with tunnels, maze boxes, and foraging toys.

• Mental Stimulation: Rats are incredibly smart and can easily learn tricks (like spin, come when called, or fetch) using positive reinforcement and small treats.

• Health Checks: Monitor your rats daily for signs of illness:

  • Clear eyes, ears, and nose (watch for excessive red secretions called porphyrin around the eyes or nose).

  • Smooth, even breathing (no clicking, wheezing, or sneezing).

  • Active appetite, healthy weight, and clean coat.

  • Always have an exotic veterinarian established before emergencies arise.
