Mice and rats can make wonderful pets for the right owner. They are intelligent, social, and relatively low-maintenance compared to dogs.
Both mice and rats are nocturnal, which means they're most active at night, so be prepared for some evening entertainment. They're also crepuscular, meaning they're active during twilight hours.
Mice are generally more timid and can be skittish around new people, while rats are often more outgoing and affectionate.

Choosing a Pet
Before adopting a pet, it's essential to learn about their lifestyles. You should also consider the differences between pet rats and mice.
To choose a pet mouse, purchase it from a reputable seller who properly socializes their mice. They should be able to identify the mouse's sex prior to sale to prevent unwanted pregnancy and fighting. Look for a mouse with a healthy coat, bright eyes, and good energy levels.

Right Rodent for You
Choosing the right rodent for you is a great way to have companionship without breaking the bank. Rodents like rats and mice are inexpensive to care for, eating less food than larger animals.
They're also low maintenance pets, requiring minimal investment to help them survive. You can find everything you need at a reputable pet store like Planet Pet, which supports local Australian businesses.
Make sure to purchase your pet rodent from a breeder or reputable seller who socializes their animals. This will help prevent unwanted pregnancy and fighting between pets.
Pet vs. Other
Choosing a pet can be a daunting task, but understanding the differences between various options can make the decision easier.
Before adopting any pet, it's essential to learn about their lifestyles, as seen in the case of pet rats and mice, which have different living arrangements.
Pet rats are social animals and thrive in the company of their human family members, whereas mice are more independent and can be left alone for short periods.
Rats are also known to be more curious and playful, often requiring more attention and stimulation, whereas mice are generally more low-maintenance.

Pet rats are also more prone to health issues if not provided with a suitable environment, such as a large cage with plenty of toys and hiding places, whereas mice are more adaptable to smaller spaces.
Ultimately, understanding these differences can help you choose a pet that fits your lifestyle and living situation.
An Overview
Choosing a pet can be a daunting task, but knowing the basics about the animal you're interested in can make all the difference. Rats and mice are popular pets, but they have different needs and characteristics.
Rats and mice require a safe and secure living space, such as a hutch that protects them from predators and the weather. The hutch should have a waterproof design and provide enough space for exercise and exploration.
A suitable hutch design includes a dark, dry area for the rats or mice to rest and hide, as well as bedding of soft hay or shredded newspaper. The other section of the hutch should have access to light and be fitted with ropes, ramps, or ladders for environmental stimulation.
Rats and mice need regular cleaning to stay healthy, which includes removing soiled bedding and ensuring they have a dry area to sleep. This is crucial to prevent respiratory infections, skin ailments, and pest infestations like fleas and mites.
Rats and mice can be good pets for children if they are treated appropriately and socialised, but they must be handled regularly to develop a positive relationship with humans. If they are not accustomed to being handled or are mishandled, they can bite.
Pet mice are scientifically known as Mus musculus and typically range in size from 2.5 to 4 inches. Their life expectancy is between 1 to 5 years.
Here's a quick overview of the pets mentioned:
Why They Make the Best Pets
Dogs are often considered to be one of the most loyal companions a person can have.
Their ability to form strong bonds with their owners is due in part to their high social intelligence, which allows them to read and respond to human emotions.
Housing and Environment
Mice and rats make great pets, but they need a safe and comfortable place to live. A hutch or cage that protects them from predators and harsh weather is essential.
Their hutch should have a waterproof design and a dark, dry area for rest and hiding. Bedding like soft hay or shredded newspaper is a must.
Good ventilation is crucial, but the hutch should be free of drafts. Regular cleaning is also important to prevent respiratory infections, skin ailments, and pest infestations.
A cage size of about 80 x 50 x 80 cm is suitable for a rat, but mice require larger spaces due to their quick and active nature.
For mice cages, it's essential to have small bar spacing to prevent them from escaping. A rodent cage with a substrate layer, water tank, and food bowl can solve these problems.
Toys are a must for mice, providing mental stimulation and exercise. A solid exercise wheel, hammocks, and ladders can keep them entertained and happy.
A secure wire cage with a plastic bottom and multiple levels is ideal for mice. The wire walls provide ventilation, while the plastic bottom offers comfort and prevents foot injuries.
To keep your mouse cage safe, make sure it's secure to prevent escape and out of direct sunlight and breezy areas.
Here are some recommended cage sizes and features for mice and rats:
Remember to add a good quality and chemical-free substrate like organic pet bedding, natural pine shavings, shredded paper, or plain wood shavings to keep your pet mouse safe.
Care and Maintenance
Rats are generally cleaner than mice, allocating separate sections in their cage for food, waste, and sleeping.
Mice, on the other hand, can be quite messy, producing up to 50-75 droppings a day.
To keep their cages clean, mice need to be spot-cleaned daily and their cage fully cleaned two to three times a week.
Cleaning involves changing out the bedding to remove droppings and urine, and scrubbing the cage with mild soap.
Rats are also tidy, but their cages still require regular cleaning to prevent odor and ensure a healthy environment.
You'll need to place your mice in a temporary safe place while you clean their cage, and dispose of old bedding thoroughly.
Fresh bedding should be added to the cage once it's dry and clean.
Health and Hygiene
Keeping your pet mouse or rat healthy and hygienic is crucial for their well-being and your enjoyment of having them as pets. A healthy mouse has clear, bright eyes and soft, smooth fur.
Their active and curious personality is another sign of good health. Regularly eating and drinking, maintaining their weight, and engaging in regular grooming are all indicators of a healthy mouse. Clean ears and feet are also a good sign.
A clean cage is essential for your pet's health and hygiene. Clean your mouse cage regularly, ideally spot-cleaning daily and doing a full clean two to three times per week. This will prevent odor and ensure a pleasant environment for your pet.
Here are some key signs of a healthy mouse:
- Clear, bright eyes
- Soft and smooth fur
- An active and curious personality
- Readily eating and drinking
- Maintaining their weight
- Regular grooming
- Clean ears and feet
Remember, a clean cage is a happy cage!
Common Health Problems

Mice can experience health issues, just like any pet. Regular exercise with toys and a wheel is recommended to prevent obesity, which is a common health problem in mice.
If you notice your mouse is overweight, it's essential to provide a balanced diet and plenty of opportunities for physical activity. A mouse's ideal weight is crucial for its overall health.
Mice are also prone to certain cancers, skin disease, respiratory disease, and diarrhea. These health issues can be prevented or managed with proper care and attention.
Here are some common health problems in mice, along with their symptoms:
Regular veterinary check-ups and a clean, healthy environment can help prevent these health issues in your mouse.
Mouse Health
Maintaining your pet mouse's health is crucial for their well-being and happiness. Keep an eye out for clear, bright eyes.
Regular grooming is essential for your mouse's health. They should be cleaning their ears and feet regularly.

An active and curious personality is a sign of a healthy mouse. If your mouse is lethargic or uninterested, it may be a cause for concern.
A healthy mouse will readily eat and drink, and maintain their weight. If you notice any changes in their appetite or weight, it's time to take them to the vet.
Here are some signs of a healthy mouse:
- Clear, bright eyes
- Soft and smooth fur
- An active and curious personality
- Readily eating and drinking
- Maintaining their weight (no weight loss or gain)
- Regular grooming
- Clean ears and feet
Handling and Interaction
Rats and mice can be good pets for children if they are treated appropriately and socialised, but they must be handled regularly to develop a positive relationship with humans.
To make sure your rats and mice feel secure and safe, pick them up gently, and if they're not accustomed to being handled, wear gloves to avoid being bitten.
Mice do not typically enjoy being handled unless they are trained to be held from a young age, so it's best to keep handling to a minimum.

To train your mice, talk quietly next to their cage to get them used to your voice, and offer them treats by hand to promote them coming up to you.
If you do pick up your mouse, gently scoop them up from underneath, paying attention to their body language, and put them back in their cage if they seem stressed.
Rats, on the other hand, love to bond with their owners and can become quite affectionate, making them easier to handle since they're bigger and more robust.
Pet mice, however, are quite self-sufficient and don't need as much attention, but they do appreciate a good playtime and will enjoy interacting with you in their own way.
If you're considering getting a pet mouse, look for one that has a healthy coat, bright eyes, and good energy levels, and make sure they show interest in interacting with you.
Diet and Nutrition
Mice and rats are natural omnivores, so they can thrive on a variety of foods.
In the wild, they can live on plants, but in captivity, they require a more nutritional diet. Commercial pet food, fruits, and vegetables can easily provide the necessary nutrients.
It may seem gross to us, but it's common for rodents to ingest their fresh poop to get all the nutrients they need. All happy rats and mice do it, so don't worry if you see them doing this!
Rats and mice are easy to feed, and they'll eat most foods. You can feed them pellets available at pet shops, along with grass hay and fresh green vegetables.
Some good options for vegetables include cabbage, lettuce, carrots, broccoli, apple, and celery. Fresh, cool water must be provided at all times, either in a drip feeder or a shallow bowl.
A mouse diet consists primarily of specially formulated rodent pellets, such as Mazuri or Oxbow Garden Select. You can also offer fruits and vegetables, like tiny cuts of apples, bananas, peas, and carrots, in a separate bowl.
Mice graze, so it's best to provide their daily pellet needs at once. Discard any uneaten food pellets after 24 hours and any uneaten fresh food before it spoils or gets contaminated.
Here are some examples of foods that are safe for mice to eat:
- cabbage
- lettuce
- carrots
- broccoli
- apple
- celery
On the other hand, there are some foods that are toxic or poisonous to mice, and should be avoided. Here are some examples of harmful foods for mice:
- Chocolate
- Citrus fruits
- Onions
- Garlic
- Raw beans
