She is letting 2 of the three nurse but I don't think she is interested in keeping them clean really. She is worn out. Young mother with her first litter. So how often do I need to take a warm cotton ball and wipe their bottoms? Also the one I dropper feed (he will not suck a bottle yet) I leave with her in between feedings. Is this best? I just came in to check on her which my vet said to minimize because she is semi feral....she will allow contact but she is NOT at all used to being in a house. Anyway when I came in to check on my runt he was up under the backside of her body and I literally could not find him til I heard his low yelps.....Should I just keep him on a heating pad with me or leave him with his siblings? He drank 1 ml three hours ago the 1.5 ml about an hour ago. He seemed a bit more interested second time around. Ideally how much should he be drinking. I have let him judge it thus far. When he becomes disinterested I don't push it.
