Will my mouse bite me?

My mice were JUST weened and in the popcorn stage of their life when I got them. After tons of research, no one had mentioned the popcorn stage. So if you get them and their heads are huge. Half the size of their bodies, be prepared for jumping and a couple nips. They jump without fear of being hurt, although when you open the carrier they'll just BONG up up and away, so some people recommend sitting in the bathtub with the curtains closed in case they get away. Don't worry though, they grow out of this REALLY quickly. They also bite cause they think their going to die and thats all they know how to do. As they age (wait a week and a bit) they'll start to never bite unless they think your food, and even then it wont be too hard. By nature, they dont bite. Just remember. Day 1 get used to their new cage in silence, Day 2 get familiar with seeing you. Day 3, start to make some noise around the cage, just talk, play some music for a bit, watch tv. Day 4-6, spend the whole day with your hand in their cage. Also, to pick them up, scoop them from the bottom, coming down on them like a claw of an owl freaks them out a ton. Something else I did was to put them on my desk while I'm working (that was after a month of trust training and they were out of their popcorn stage) Be prepared for them to poop and pee with fright, although it's a good sign if they hold all their bowl movements in. That means they like you and are not scared.

A mouse will only bite you if it smells food on you, which will make it bite you, so wash you hands(or yourself if its necessary) before holding or going near your mouse. And, maybe it would be a good idea to buy the supplies first, so you're prepared. Building it up first would also be smart because if you build it after you get the mouse, the mouse will most likely wander off(so make a backup plan!).

Only if it smells fear or food
