I just recently found a baby mouse. It had fur when I found it and it's eyes were not yet open. I searched the internet and this website was very helpful! http://mouseranch.com/FYI/orphans.shtmlhope this helps!
You can tell a baby mouse is a mouse by looking at its size, shape, and features. Newborn mice are tiny, hairless, and pink, with closed eyes and big round ears that lie flat at first. As they grow, they develop soft fur, their eyes open at about 2 weeks old, and their tails become long and thin — about the same length as their body. Baby mice are also much smaller than baby rats; they have smaller heads, more delicate features, and shorter feet. If the tail is long, the ears are large goto.now/YJkWW👈🏻
born with there eyes open
They are probably about a week old. You can see pictures of a rat litter (very similar in development to mice) at http://www.noselicks.com/shirelings/ The pictures show the daily changes in a litter of pups as they grow from birth to a few weeks old.
It takes about 2-3 weeks for a baby cat to open it's eyes.
Yes, it is very unusual for a mouse to be born with its eyes open. Most small mammals are born with their eyes closed.
a baby ferret is born with eyes closed
Before baby mice open their eyes, they're too young to be weaned. The mother mouse will feed them milk. If the babies don't have a mother or have been abandoned, they'll need to be fostered or hand-fed, or they won't survive.
food
No. The mouse is perfectly normal. Some times the eyes open at different times. It's all good though
