Baby pet mice are often referred to as kittens or puppies (or pups). Extremely cute, baby pet mice are a big responsibility for the owner and require a lot of care in terms of the environment they live in. If you have a pair of pet mice (male and female), chances are that you will end up with some baby pet mice sooner or later. If you choose to hold onto them, then there are a number of things that you need to take care of.

The most important thing to understand is that an expecting mother needs to build a nest where she will give birth to baby pet mice. It is important to provide her with all the material she would need for that process and that means extra shavings and bedding material. Most mice prefer to give birth when alone – a natural instinct that comes from being in the wild. If you happen to be around, try and be discrete if possible and not disturb her too much during the process.

Once you have pet baby mice, it is important to focus a bit on the mother and ensure that her health remains good enough to feed the babies. Pet baby mice tend to feed quite frequently and it is important for the mother to be able to sustain that level. You can help by having food on standby at all times along with fresh water. Some may suggest spiking the water with essential vitamins just to give some additional boost but in most cases, plain water does the trick.

By about the third day, the pet baby mice begin to display pigmentation under their skin and there is a semblance of colour that begins to take shape. At this time, you can sort of make out the variety of mouse each will turn out to be although the clarity of the markings (if any) will not be seen until they have grown up a bit.

By the 14th day, pet baby mice begin to open their eyes and their fur also begins to take shape. This is when they begin moving around the cage. It is important to have a cage where these little creatures can find footing and not a normal wire mesh cage with just a layer of shavings as the floor because they can easily pass through the gap. So you need to ensure that the wire cage (if that is what you are using) is not wide enough for the pet mice babies to fall through.

Pet mice babies are extremely hyper-active creatures and their job is to jump around, tire themselves out, feed to regain energy and then repeat the cycle. This is the right time to put exercise equipment into the cage as these young ones jump to the chance of exploring something new. It could mean hours of fun for you, watching them trying to master a wheel you just placed in the cage.

By about three weeks, these pet baby mice are almost completely developed and this is when they begin growing rapidly. In a small litter, the babies get more access to nutrition from the mother and this is vital to grow quickly. By this time, the baby pet mice are a joy to watch as they begin playing with each other and everything around them. They begin to grow teeth and then, almost everything in sight is nothing more than a chew toy.

By their sixth week, baby pet mice are all weaned and ready to leave their mommy’s side. Their characteristics are more pronounced as are their markings. This is also the time when the males need to be separated from the females as both start hitting that age when opposites attract.

Once weaned, baby pet mice are at their final stages before reaching adulthood and it is the right time to find new homes if you are looking for some.

If you are a breeder, then it is always advisable to keep each litter separately. Mixing litters of different ages or introducing new baby pet mice to an existing litter doesn’t go down well with either as mice tend to form a community of their own and outsiders aren’t really allowed.

Whether breeding pet mice or simply rearing them, you will always find immense joy when you wake up to the noise of little squeaks coming from within your pet mice cage. A new born is always a joyous occasion and an entertaining one too, in the case of pet mice babies.
