My fiance's friends have a female cat who just had kitten. By their size I would say they are about four weeks. Well the momma and babies all have colds. The momma seems ok, but the babies have at least one eye crusted over and one of the babies has two crusted over. You know what they're going to do about it????? NOTHING!!!!!! I am so ticked at them right now. They are so irresponsible.
