Awwww! I have a friend who took home 1 day old kittens from the SPCA to foster. She had a little bitty baby bottle with KMR(kitten milk replacement) that she fed each of them every so many hours either every 2 or 4 hours (morning and night) and had to stimulate each of them after to go potty. I belive she took a damp papertowel and would rub their bottom until they went.

You can also try doing a search on google.com or something like it for orphaned kittens or hand raising kittens.

Good Luck. Hand raising a kitten can be a big undertaking but also very rewarding.
