It turns out that their ability to smell is much better than ours. Moreover, they rely on touching and the feeling of warmth near them can easily bring them to their parents. Once their ears develop, they start to rely a lot on their hearing too.

Can Baby Mice See in the Dark?

No matter the lighting conditions or whether your mouse is a baby or an adult, mice can’t see well in general. Their eyesight is blurry and it helps them distinguish between shapes while they can’t see fine details. They can follow movements that happen around them and that’s all.

In the dark, the situation is even worse but their other senses help them a lot in figuring out what is happening around them exactly.

Conclusion

We can conclude that baby mice are pretty helpless, which is why they rely so much on the care of their parents. They can’t see nor hear anything in the first two weeks, yet they need to be fed in every two hours. It helps them a lot to stay near their parents who are eager to defend and feed them.

They even sleep together, providing warmth and protecting them from the potential dangers lurking out there. If you have a few mouse babies but the parents are not there, you can raise them by yourself without a problem.

Just make sure that the temperature is warm enough in the room and feed them in every two hours. Before you know it, they will become strong and happy adult mice who are eager to play.
