How to Care for Pet Mice: A Beginner’s Guide

Mice are tiny, adorable, and surprisingly low-maintenance pets, making them a great choice for first-time pet owners. But like any animal, they have specific needs to stay happy and healthy. Whether you’ve just brought home your first mouse or you’re thinking about getting one, this guide has everything you need to know about caring for these little cuties.

Why Mice Make Great Pets

Mice are small, affordable, and full of personality. They’re curious, playful, and fun to watch as they explore their surroundings. Plus, they don’t take up much space, making them perfect for apartments or smaller homes.

Setting Up the Perfect Mouse Home

Cage

• Size: Even though they’re small, mice need plenty of space. Aim for at least 200 square inches of floor space for one mouse or a small group.
• Type: Wire cages with a deep plastic base or glass tanks with secure lids work best. Avoid cages with wide bars—they can squeeze through tiny gaps!

Bedding

• Use paper-based bedding or aspen shavings. Never use cedar or pine—they’re toxic to mice.
• Add about 2-3 inches of bedding so they can burrow and dig.

Accessories

• Hideouts: Mice love cozy spaces to sleep and feel safe. Small wooden huts or cardboard boxes work great.
• Toys: Add tunnels, climbing structures, and chew toys to keep them entertained.
• Wheel: Get a solid-surface wheel (no wire or mesh) to prevent injuries.

What to Feed Your Mice

Main Diet

• High-quality mouse food or lab blocks should make up most of their diet. These provide all the essential nutrients they need.

Fresh Foods

• Treat them to small amounts of fresh fruits and veggies like apples, carrots, and broccoli. Avoid citrus, onions, and garlic—they’re harmful to mice.

Treats

• Offer occasional treats like seeds, nuts, or small pieces of cooked pasta. Just don’t overdo it—mice can gain weight quickly!

Water

• Always provide fresh water in a small water bottle with a metal spout. Make sure it’s clean and refilled daily.

Handling and Socializing Your Mice

Building Trust

• Start slow! Let your mouse get used to your presence by sitting near their cage and talking softly.
• Offer treats from your hand to build trust.

Picking Them Up

• Scoop them gently with both hands or let them climb onto your hand on their own. Never grab them by the tail—it’s painful and can cause injury.

Social Needs

• Mice are social animals and thrive in same-sex groups. Lone mice can get lonely, so consider getting at least two or three (just make sure they’re all the same gender!).

Keeping Your Mouse Healthy

Common Health Issues

• Respiratory Problems: Watch for sneezing or wheezing—it could mean they’re sick or their bedding is dusty.
• Overgrown Teeth: Provide chew toys to help keep their teeth trimmed.
• Weight Issues: Mice can gain weight quickly, so avoid overfeeding.

Signs of a Healthy Mouse

• Bright, clear eyes
• Smooth, shiny fur
• Active and curious behavior

Cleaning the Cage

• Spot-clean daily by removing soiled bedding and uneaten food.
• Do a full cage clean once a week, replacing all bedding and washing the cage with pet-safe cleaner.

Fun Facts About Mice

• They’re super smart: Mice can learn tricks and even navigate mazes!
• They’re night owls: Mice are most active at night, so don’t worry if they sleep all day.
• They’re tiny hoarders: Mice love to stash food in little piles around their cage.

Final Thoughts

Mice are small in size but big on personality. With the right care, they can live happy, healthy lives and bring a lot of joy to yours. If you’re ready to care for these tiny adventurers, start by setting up a cozy cage and showering them with love and attention.
