A friend just got a pair of fancy mice for her children. They are trying to get the mice accustomed to the humans, and my friend said one mouse already bit her, "but it didn't hurt too much".
I've had mice before and know that they can bite strong enough to draw blood. I also have made the mistake of not teaching a cat to not bite humans when he was tiny and his bites were cute; we couldn't re-educate him as an adult. So, if mice have the ability to learn to not bite, I think it will be in my friend's interest to try to teach them. She told me she is not sure how she should react, but I didn't feel qualified to give advice.
Should my friend try to train them to not bite humans, or is this impossible with mice? If she can train them, what approach can work? If she can't train them, how should she behave? Ignore the bite? Put a distance between herself and the mouse?
She mentioned that the mice are already losing some of their anxiety towards the humans, and she thinks the bite was exploratory behavior, not defense.
