My queen Balinese delivered a litter of 5. Prior to the delivery her nipples were flat and my vet said they would come out once the kittens started nursing. I spent 9 hours on the day of delivery pinching and pulling her nipples and only could get 4 to be used. unfortunately one of the kittens weighs half the weight of the others and frequently gets pushed off. We have been feeding him by tube feed since he doesn't have a good nipple. Has anyone dealt with this and have you heard of a nipple puller. We called two other vets besides our own, we talked to our two mentors and none had heard of a nipple puller. My one mentor said to use a warm wash cloth and rub the nipples frequently. This was the only thing that helped, but wasn't enough to get all the nipples working.
