1. Mice have very restricted vision, and like most
mammals, are color-blind. They only have two
channels for perceiving color information
(dichromate), as compared to most humans who have
three (trichromate). Their vision is similar to
red/green color blindness in humans. Color for
mice seems to be less important than brightness
is. Additionally, mice vision is very blurry, the
equivalent of about 20/2000 human vision.
2. The house mouse has a lifespan of about two to
three years, although the world record for a
genetically engineered mouse was almost 5 years.
Females reach maturity at about six weeks after
birth, and males at eight weeks. Both can begin
copulation as early as five weeks.
3. Mouse give birth to a litter of 3 – 14 (average
6 – 8), and one female can have 5 – 10 litters per
4. The general care instructions are to leave the
mother mouse and her litter be, as any disturbance
can cause her to be agitated and abandon the
babies. Provide the usual food and water, and
(ideally before birth) give the mother some toilet
paper or tissue to help her build a nest. Avoid
handling the babies or interference of any major
sort for at least two to three weeks.
5. In the wild, mice are primarily herbivores,
consuming any kind of fruit or grains from plants.
Some mice have adapted to urban areas and will
eat discarded food scraps. As pets, mice are
typically fed a commercial pelleted mouse diet
that generally consists of the necessary grains,
fruits, and vegetables. The pellets are crunchy
to help maintain the mouse’s teeth.
1. Humans have three types of cells in our
eyes, which absorb blue, green, and red light.
Mice, on the other hand, only have two types. So,
mice are color-blind, similar to how some humans
(mostly males) can be color-blind. More studies
are being done with mice vision and how it can
relate to humans.
2. Male and female mice start their mating with
calls that attract one another. A gestation period
of about 19-21 days is followed by mating. So, a
human baby is growing for 9 months whereas a baby
mouse is growing for about 19-21. This means that
many mice can be born within a year. On average,
mice live for 1 1/2-2 years, but some can live up
to 3 years.
3. Usually about 5-10 mice are born in a litter.
Reproduction happens all year long for mice,
except those in the wild because they usually
hibernate during the colder weather periods.
4. Pet mice are selectively bred, which enhances
their qualities to be better pets. As you can tell
some wild mice may not be as nice as your pet
mouse. The first things for new born mice is to
make sure they are in a warm, safe, and
comfortable environment where they are not
bothered by other pets in the house and are
cuddled up. Feed the mice a heavily diluted baby's
milk formula. Do not give them cow's milk because
it is too harsh and they can suffer digestion
problems which can lead to their deaths. You can
use q-tips dipped in warm water to clean the mice
and progress digestion. When the babies start to
open their eyes, you might give them crumbled
crackers and more solid foods to get them used to
what they will be eating when they are older. And
don't forget to play with them!
5. It is important to feed mice a healthy and
balanced diet. Pellets or any mouse food mix
available at the pet store is good. You can also
add some grains and seeds. Since it is very
important that the mice is properly nourished
(some can be picky eaters), you can supplement
their pellet diet with things like, fresh fruits
and vegetables, lettuce, sunflower seeds, and
whole grain pastas. Make sure you never feed the
mouse chocolate because it is toxic and can be
fatal. Also, every mouse is different so you
should see what the mouse likes and what causes
the mouse problems (diarrhea, etc). As you can see
a lot of these "supplementary" foods are ones that
can be found in the wild, and these are the foods
herbivorous wild mice eat. Some wild mice can be
omnivorous and will eat insects, snails, and
centipedes in addition to their veggies.
Mice see two-color vision, like dogs (or
"color-blind" humans). This means that they can
tell blue from yellow, but can't tell green or
yellow apart, and red looks black to them. The
range of mouse vision is about focusing the lenses
in their eyes; they can see light from any
distance, but I don't know how nearsighted they
are, so it may be blurry.
