Okay, my cat had kittens about 5 days ago. It was a litter of four. One of them seems to have something wrong with it's eyes. The other three have their eyes closed because obviously kittens are born blind and they don't open them until awhile. Back to the problem, one of the kittens has had it's eyes slightly open and it appears there is something wrong her. Is this normal? Is she going to be blind? Should we go take her to a vet?
