9 Practical Facts About Mice As Pets

1. Is a Pet Mouse or Mice a good suit for you? 

Before you adopt that little mouse or nest of mice, you should know some things about these little critters. There are many misconceptions about them, such as just being a feeder animal, cheap to care for, requiring little commitment, or just being a pest.  

2. Their Life Spans are Quite Short 

This will either be a pro or con, depending on what you are looking for. The average lifespan of a mouse is only around two years, maxing out at three years, so they will be shorter commitments than other small pet animals.  

Mice start their lives as pinkys, after their mother gives birth. A Mother mouse can become pregnant by a buck, a male mouse, as soon as six months, so if you plan on keeping both sexes you will need to keep them separate.  

3. They Are Social Animals 

Mice are social animals and are happier when they are kept with at least another same-sexed mouse, preferably from the same litter. Few bucks do not get along with other mice, and will need to be homed alone, but maybe happier if there is another cage nearby of mice to communicate with. 

Mice As Pets Pros And Cons

4. Low Costs & Maintenance (PRO)

Most mice owners can keep their pets healthy and happy for only about $15-$25, depending on your chosen pet store. This cost makes up bedding, their pellets, chew toys, and treats, though it is advised to choose treats from your kitchen versus packaged. You may also need to replace some of the initial items, such as their hide home. They do not require salt or mineral stones.  

It is advised that you save about $250 per mouse, as this is the cost of an average vet bill.  

The largest cost will be buying al the initial items. This would include their cage, a wheel, a water bottle, and places to hide.    

Overall, the cage that is suggested to get is a 10-gallon tank with a cage topper or 20-gallon long tank, though some mice are happily housed in a bin cage or a wired cage. The length of the cage should be at least 20 inches, the width 10 inches, and at least 15 inches tall so that there is space for them to climb. If you are choosing to go with a wired cage, make sure the bars are not more than ¼ inches apart, and that there is enough space to provide at least 5 inches of bedding.  

Mesh wheels are suggested, though plastic will do. Depending on your cage, you may have to be more creative in attaching a water bottle, but any aimed at hamsters or small animals will do. You will also need a food bowl that can hold around half a tablespoon per mouse. The hide homes can vary in price, or you could build your own.  

5. They Are Quiet (PRO)

Mice, for the most part, are pretty quiet. Their squeaking and other vocal communication are quieter in comparison to other social small animals, and as long as you have a silent wheel you should not be bothered much by their noise levels.  

6. Good Starter Pet for a Mature Family or Person (PRO)

While mice do not particularly get along with children, they can make a wonderful first pet for someone mature enough to learn their care and proper handling, because of their reclusive lifestyle and low cost to care for them.

Also, because they tend to have shorter lives, they are a shorter time commitment, and if you would like to try your hand with other small animals after, you can most likely repurpose most of their leftover things. 

7. Not Good with being Handled (CON)

While you can hand feed mice, and it is suggested, they most likely are not the pet for you if you want a ton of cuddles. They can eventually be trained to climb into your hand but may try to jump if you try to remove them from their cage.

When adopting older mice, this chance is risen, unless handled well when younger. But, if you are looking for a pet you can observe more, or do not want to carry too much than they are a good choice in a pet.  

8. They Are Nocturnal (CON)

The reason most house mice take a while to be found is usually that they only are active at night. This is the same with pet mice, though they may make their presence known sooner, around twilight, when in a habitat they are more comfortable in.  

9. Not Good with Young Children (CON)

As mice tend to be timider then other small animals and less cuddly, they would not be good for families as a started pet. Though small pets are not recommended for any child under four, and the parents make sure the children are handling them properly.

A child may squeeze a mouse or other small animal to try to keep a hold of it, and if dropped, there is a high chance the mouse may be harmed and will run away, turning most likely from a pet to a pest.  

Are Mice Good Pets for You?

If you are looking for a pet that you will not have to worry about outliving you, such as a turtle, with a low cost to care for, a mouse or mice are a good pet choice for you. They only require minimal care, which makes them a great starter pet, as long as the family it is mature enough to learn to properly handle them.
