I'm not going to pretend to know much about hand feeding an animal, because I don't. My friend has a litter of 6 kittens.. the mother just up and disappeared two days after they were born. She was feeding them with an eyedropper and for some reason... the milk comes out of their noses. What does this mean?
That could mean on of two things, that they are being fed too quickly or that they are full.
That is why I used a feeding kit with the tiny bottle. I used a hot needle and poked a few holes in the nipple. The opening should only be big enough so that a few drops come out when shaken vigorously.
Be careful they do not get the milk in their lungs at this early of an age they can develope pnuemonia and because they are so weak they cannot fight it off.
