I have kittens that where born May 23, 2005. I recently went on vacation and my mother watched them. I was worried about them starving while I was gone because according to the baby kitten calendar they should be weaned. I got food and tried everything for i left. i called a vet and she said the mother will wean when its time not to force it. Again I explained I was going out of town. So I went and got wet food for my mother to put out every day. I came home last night and they are eating hard food and will not have nothing to do with soft. Is this ok? Any words of wisdom?
