Mice are considered part of the rodent family. Their scientific name is "Mus musculus".
Mice have an average life span of 1.5-2.5 years.
To properly sex a mouse, the distance between the anus and the genital opening is measured. Males have a space twice the distance of females.
In general, mice are very cute and popular pets that require minimal care. They do tend to get sick once in a while, and when they do, it is usually severe. mice are definitely cute and small, but they can bite hard. They are usually territorial of their own surroundings. Your mouse should feel safe and not try to bite with routine handling. Never abruptly awaken your mouse as they tend to hibernate and can scare easily and bite if not approached carefully and gently. It is best to house your mouse alone and away from your other pets. He or she will feel safer this way.
There are three basic reactions mice can have to fear.
All mice will react in one of these 3 ways to fear. These are characteristics that are a result of instinct and the genetic code. There are no bad mice. If a mouse is afraid enough it may bite (fight response to fear). Even if we don't like an animal's behavior (and the behavior is "bad"), the animal is not bad. Of the three responses mice can have to fear, let's look at each one and see how they affect our mouse.
This is one way mice react to fear. This presents itself in the form of chewing or biting. These animals are not bad, they are simply afraid, and this is how they deal with it. Unfortunately, it can be challenging in a household to have mice that react to fear with a fight response. Since they are simply afraid (just like mice who react with freeze or flight), if we are emotionally hurt or offended and fight back (hitting, yelling, etc), this will only make them more afraid.
mice that freeze stay very still. Sometimes they even hold their breath for long periods of time. They can continue chewing or stop chewing. If you see this (and you probably will), just notice it. If you are observant you will start to notice what you can do to help your mouse feel less scared.
This is when a mouse feels unsafe and runs away. Some mice freeze first, then, when the time is right, they run away. Since mice can run from fear, chasing them makes them more afraid, so if you can it's best to give them the space and let them come to you. Some mice will do this quickly; some may not come to you for weeks to months (or longer). But it always helps to know it's not you but simply that your mouse is afraid. Don't feel bad or guilty or wrong, just notice when your mouse is the least afraid and interact then.
When a mouse is afraid they can react in any of the three ways we discussed, but there are several interesting points.
This is vital information because you can notice where your mouse is, and you can make changes to help your mouse feel more safe (such as putting your baby down, picking your baby up, stopping petting your mouse, or changing the environment).
