Yes, it is very unusual for a mouse to be born with its eyes open. Most small mammals are born with their eyes closed.
Many mammals are born with their eyes closed like this. It has to do with whether or not the babies need to see right after birth or not. Mice (and rabbits) are born in dark burrows and cared for by their mothers, so they don't need to have their eyes open right away. Animals like horses need to see if a predator is approaching, so they're born with their eyes open.
Their eyes open around 2 weeks of age.
hhighnkk,
Baby mice are born blind and their eyes remain closed until around 10-14 days after birth. Their eyesight develops gradually as they grow, with full vision typically achieved by the time they are a few weeks old.
mice' eyes open at aprox. two weeks. they need to be able to nurse for at least a month before separated from their mothers.
not always sometimes there eyes will be open just depends on how they die usually
yes all Giraffes are born with there eyes open
Two weeks after they're born, to the day, baby mice first open their eyes. Mouse eyesight is not very good though--they rely much more strongly on their sense of smell and touch.
yes they can it's quit weird when you think about it.
They remain eyes once they open!!
Don't worry. They'll open their eyes soon. If, after a few more days they don't, you should contact your local vet.
not all babys are born with their eyes open ,my mom said i was born with my eyes closed and they did not open for 3 days.
