She spends all day away from them now and won't let them nurse unless it's on her terms. I have one male that refuses to eat dry food. All of the other kittens are nice and plump and eating food and using the litter box just fine but this one boy won't eat the food and only wants mom but she's pushing them away. I don't know what to do since mom won't feed him half the time and I cannot leave out anything but her food for them because she'll eat it and get sick. She has to stay on the pea and duck or pea and chicken food. They are 6 weeks old tomorrow. He seems very healthy just on the thin side. He plays with the other kittens and plays with us he just wants momma milk.
