Mice live very dangerous lies, and they have many predators, so it is common for mice to have a lot of babies.

The average litter a mother Mouse can have is anywhere from 4 to 11 pups. It can have any amount of pups within this range, depending on their health and the environment they live in.

How many babies do mice give birth too?

On average, a mother mouse can give birth to a litter of four to eleven pups. For such a tiny animal, this is a lot of babies.

Frequently, when they have pups on the higher range like 8 to 11, the mother mouse will be obese to the point where she can barely move. If she gives birth to pups on the low side, like three to 6, she still will be fat but should be able to move around and even run a bit.

However, you may be relieved to find out that a mouse can be sterilized or neutered. Of course, neutering or spaying for a mouse will take specialized surgery that not many veterinarians know how to do, but it is possible. 

What helps a mother mouse give birth easier?

There are several things a human and a mouse caretaker can do to ease the birthing process. First, make sure that the bedding in your mouse’s cage is clean at all times. Make sure the food and water are always fresh and replenished, and there is no poop around the cage. As time draws closer to her birthing, she will be more nervous and cautious than usual.

You will not see her running around her cage as she did when she was not pregnant. During this time, female mice are incredibly vulnerable and are more at risk of being killed by predators. While she may be in the cage now and safe from predators, this instinct is already ingrained in her mouse brain, so she will hide more, especially in the last few days before her birthing process begins.

It would help if you also moved her cage into a dark and unbothered part of your room. One popular place to place the cage is in the closet. Keep any other animals away from the kid while she’s pregnant, while she’s getting birth, and two to three weeks after giving birth.

If she is giving birth, you must not bother her. Your presence is unwelcome and uninvited. Do not try to pet her or add food and water to her cage. She may try to run away. This means she will run all over the cage and place a great strain on her body as she is still getting birth.

The entire birthing process for a mouse can take up to two hours. When she is done giving birth, then you can add extra food and water. You may be tempted to clean the cage of all of the birthing material, but this is a bad idea. Leave her completely alone with her pups for the first week.

You may be tempted to pet the new pups, but do not do this. Mice are known for abandoning their pups if they have been handled by another creature.

How to care for the new pups?

First, do not move or bother the new pups for the first week of their life. They need to be with their mother so their mother can bond with them. If their mother does not bond with them, she will refuse to take care of them.

Second, when a week after they have been born has passed, you must clean out the wedding of the cage, remove everything that the mother mouse gave birth on. Add fresh new mice bedding to the cage and new litter as well. 

If you are cleaning the area around the cage, do not use any harsh chemicals for sprays. If you have to clean your room, gently pick up the cage and place it somewhere else why you clean. Mice are extremely sensitive to everything around them, and this includes chemicals and cleaning solutions.

When the baby mice reach about three weeks old, the sex of each mouse must be identified, and then each of the mice must be placed into a separate cage. If this does not happen, the male hamster will try to mate with their sisters and get them pregnant.

Do mice eat their young?

Unfortunately, yes, mice and other rodents are known for eating their babies. It’s actually more common than you think in the Animal kingdom to see cannibalism. There are two main reasons why a mother mouse would eat her young. 

The first reason a mouse would eat one of her younglings is that she is stressed and cannot find a good food source. The birthing process is an incredibly tiring process, no matter what species you are, so she will not be able to leave her pups and scavenge. However, the mother does have self-preservation. She will take care of herself by choosing to eat one of her younglings. It’s very common for the mother mouse to eat the runt of the litter so that larger pups can have a better chance of surviving.

The second reason she will eat her young is that the runt of the litter is holding everybody back from developing faster. In the animal world, there is no protection against terrible Predators. So, instead, the mother Mouse will eat the smallest pup of the litter. If she eats one or two of her pups, that means that they will be more milk for the other pups. She will not have to drain her energy drink away from her body in order to feed more pups.
