My mice are going on 13 days old and still dont have their eyes open?

Hey were born the 28th of may and they dont have their eyes open yet are they just late developers or should I be worried. They have all their fur and are getting around great, This is my first litter of babies to care for.My mice are going on 13 days old and still dont have their eyes open?
Completely normal. Believe it or not, most mice will open their eyes on the 14th day of life. However, it can extend to up to 20 days! Don't worry about it, I'm sure your babies will be a-okay.My mice are going on 13 days old and still dont have their eyes open?
Eyes are the last thing to develop on a small rodent. So, it is completely normal. If everything else has developed normally, then there should be no worries. If they do not open in the next four or five days, then you should take them all to your local vet. But another sign that it is normal, is that all of the rats don't have their eyes open instead of just one or two runts.





hope this eases your concerns :0)
they should open in a day or 2, they open usually when they are 14 to 17 days old, if they don't open ask at a pet shop or call a local vet for advice, good look, hope i helped
