That's right. The only nipple kittens with a mom will take is mom's. That's why I said in my above post that unless they will lap it from a dish, at 3 weeks old you'll have to syringe it.
Yes I did get the hang of it they are 4 1/2 weeks now and all are eating out of a dish. Almost are a pound and a couple ounces and the runt is 15 ounces. I am strictly feeding wet canned kitten food. Mixed with the kmr. They are all turning into little pigs and we are going through 3 cans a day. Mom nurses them after we are now working on box training them and we have good homes for 3 of them the other two will be staying with me. Moms spaying is scheduled for right after Christmas I don't want to fix her till after they are 8 weeks. Invade it will cause her to stop nursing. I need to pick up other liter for them as they try to eat what we have what is the best kind of liter to use. I saw a clay based one is what is recommended. The runt is now thriving. He fought us on the syringe so we mixed with a little wet food and finger feed him for a few days a few times a day.
