Jen is right , cow milk is not good for kittens. But is better than nothing. I have seen rise new born kitties with cow milk diluted in some water, way back before the replacement formula was avalaible at the pet shops.

For feeding I used a very small serynge, and follow the kittens sucking rhythm.

I raised 3 little one in April let me see if I found the thread, I got wonderful help and related links.

Good luck!
