This is my first litter. There are 5 of them. Californians. They are 3 wks old today. One of them has both eyes not open, and another has just one eye open. Everything I have read says they should have their eyes open by 10-14 days, so I thought maybe there was something wrong. I used some warm water and a soft cloth, but they are not crusted shut, not red, doesn't appear to be any problem, except they're just not open. They are even drinking out of the water bottle, eating a bit of pellet, and bouncing around the cage just like the other three. Any ideas or suggestions?
