If Your Mouse Has Babies, What Should You Do?

Mice litter

You may be astonished to find a litter of offspring in your pet mouse's cage shortly after taking her home if she was unintentionally bred at the pet store. You could be shocked with a litter if you bring home two mice who were mis-sexed. But don't worry; with a little care from you, the new mother mouse should be alright!

What to Do When Your Mouse Has Babies

If a mouse that has recently given birth is disturbed, she may get upset and leave or ignore the pups. This implies that during the first few of weeks, other from giving food and water, you should leave the mice and their cage alone as much as possible. While it may be tempting to check on the infants to ensure that everything is in order, it is important to let the mother do her job.

Make a soft nest in the cage with strips of toilet paper or face tissue. You should do this as soon as you learn your mouse is pregnant (it is usually pretty obvious by a couple of days before birth, simply by the sheer size of her belly).

If you discover your mouse is expecting, clean it well to preparation for the impending arrivals. However, don't clean the cage for a bit after the pups are born. For the first 10 to 14 days, let it alone (you can spot clean really wet spots if absolutely necessary, but avoid disturbing the nest).

Make sure to provide plenty of food and freshwater, but make and watering as efficient and calm as possible.

While it is okay to have a quick peek in the cage on occasion, avoid sitting and watching for long periods.

Keep in mind that the mom will be very protective and may act more aggressive than usual; this is natural and no cause for concern.

Though interference should be avoided whenever possible, if you must transfer a baby for whatever reason, use a spoon to prevent getting your fragrance on the infant. Even if a youngster is out of the nest, it is rarely required to transfer them; the mother will typically recover any wayward puppies and return them to the nest.

Caring for the Litter

It may be good to let additional female mice in the cage if you have a litter, since they will frequently assist in the care of the litter. However, another female may attempt to take over a litter or cause other interference, so make sure other females are assisting the new mom rather than hindering her. However, if you have a male mouse, now is the time to transfer him out, both to avoid another pregnancy (which can occur soon after birth) and to ensure that he does not interfere with mom rearing the litter (which is uncommon but possible).

The baby mice will be ready for weaning at about 3 weeks of age, and it is best to separate the male pups into one group and the females into another at this point.

Make sure you're feeding a high-protein, high-quality meal. To give the mom a nutritional boost, you may provide tiny portions of hard-boiled egg, morsels of cooked chicken, cheese, wheat germ, or dog biscuits in addition to a good-quality diet.

Unfortunately, if you bought a pregnant mouse from a pet store, she can be relatively young and not the best mother. She could be more prone to abandon or even eat her children. It is exceedingly difficult to preserve the infants if she does not care for them and they are less than 10 days old. For at least two weeks, avoid handling the newborns at all. To avoid shocks like these, make sure you get your mouse from a business that separates males and females at a young age.

If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
