As fosters we received a mother with five kittens about two days old. One passed away while four are thriving now at eight days old, their eyes are starting to open. We were brought four more newborn kittens today, vet said mother had no milk. (Which I never heard of before) We are trying to tide them over for now. I removed four original kittens and let the mother (who nursed them readily) the four new kittens. My main question is will she start producing more milk for the extra ones? I am planning on syringe/bottle feeding the older kittens to supplement them while the newbies are getting started. I have both in separate beds with heating pads beneath them. Now what?
