Do Pet Mice Bite? 5 Tips to Avoid Mouse Bites

Mice take some time to build trust with you. At first, the mouse you bring to your home will not trust you, and you will have to earn that trust. They will hide and elude you at the start, and when you will try to pick them up, they might also bite you.

You’ll need to be extra careful and sensitive about handling the mouse right at the start. Some encouragement and careful care will slowly allow you to build a rapport with it. Biting is very common, especially at the very start.

In this article, we’ll take a look at how to avoid mouse bites and prevent them from happening in the future. While mice bites do not hurt that much, it’s slightly annoying to see that your mouse doesn’t trust you and starts to bite you when you approach it.

Tips to Get Your Pet Mouse to Stop Biting

Biting is not a form of aggression, but is rather a form of protection that the mouse uses when it feels threatened. It might make sense to ease the feeling of uneasiness of the mouse when you’re around. You’re an intimidating figure for them, and you’ll need to build some trust with it. Here’s how.

Tip #1: Build Trust with Your Pet Mouse

Building trust with your new pet mouse will take some time, and you’ll have to care for the mouse in these times. Don’t be too aggressive with this, as you introduce yourself to the mouse. Do it slowly and carefully, and avoid handling the mouse too much at first.

Instead, show the mouse that you’re there to care for it, instead of posing yourself as a threat. Trust will come with weeks or months of good care, careful feeding and gentle handling. Interact with the mouse when you can, but don’t be persistent if the mouse doesn’t like it. Take it slow.

Tip #2: Handle Your Mouse the Right Way

When you want to build trust, you can start to handle the mouse more often. But don’t overdo it, and you have to do it the right way.

Handling the mouse too aggressively can make them uncomfortable, especially if you hold them too tight. Instead, caress them gently, and start to gently pet them. Maybe you can ease the process with some treats to make the mouse feel more comfortable.

Also, avoid handling the mouse too often. This can cause excess stress, and you don’t want that, especially at the start.

Tip #3: Give Your Mouse Treats Before Picking Up

Yes, giving your mouse some tasty treats might help build more trust. If you want to pick it up, maybe feed it some treats from your hand, or put it somewhere near you to help them build more trust.

After you see that your mouse gained some courage, you can gently pick it up into your hand. Handle the mouse gently and give it some treats to encourage it. After some time, you’ll notice that your mouse trusts you more.

Tip #4: Mice Need Social Life

Yes, mice are social creatures. They need engagement, they like to be around you or other mice. But you’ll have to be careful with this as if you put them too close to other mice, they might get restless and some mice can even get territorial.

You can also consider putting some toys into the cage or tank. This can ease the socializing process for the mice, and make them trust you more. But most importantly, they like to be engaged, to interact with you or other mice.

Tip #5: Don’t Stress Out Your Pet Mouse

Stress is a problem with any creature, and even more so with mice. They are fragile, and excess stress can cause diseases and even death. Fortunately, you can do a lot to reduce stress levels significantly.

First of all, make sure they are comfortable and cozy, and that they’re given enough space. As some mice are intimidated by other mice, they might turn aggressive. Also, make sure they get more than enough food to survive.

Stress can also come from the outside, and it can be other pets, especially cats can cause stress, but dogs as well. Keep them somewhere quiet and away from stressful factors.

Does a Mouse Bite Hurt?

Even though the mouse’s front teeth are quite sharp, the mouse bites won’t hurt that much. You’ll feel them more like a pinch rather than a bite. But mouse bites are not pleasant because you’ll know that the mouse doesn’t trust you. It’s a form of self-defense, but it doesn’t hurt that much if a mouse bites you.

Are Mouse Bites Dangerous to Humans?

Bites from mice that you know and keep in your cage are generally not dangerous. However, if you get bitten by a mouse from unknown background, it can transmit some bacteria or diseases that you can contract. But generally speaking, mouse bites are not dangerous to our health.

Can a Mouse Bite You While Sleeping?

It’s possible, but highly unlikely. If you keep your mouse in a cage at night, then it’s virtually impossible. In some cases, it can happen, but it’s unusual as the mice will only bite when they are in danger. A mouse is very unlikely to attack you on your own, and they will only bite when they feel threatened or in danger.

How to React to a Mouse Bite?

It’s easy to be annoyed by a mouse bite, but it doesn’t hurt that much. Stay calm if a mouse bites you, and don’t throw your mice or treat it badly. That will only make it worse, as the mouse will lose all the trust it had. Instead, put it down gently and release it, and try to build up the trust for the future.


Mice bites can happen, but they are not severe. You can decrease the likelihood of bites by making yourself familiar to the mouse. Mice usually bite when they feel endangered, not to attack.
