KweeN, you definitely want to get some KMR (kitten milk replacer), and a small nursing bottle designed for small puppies & kittens. (The nipples usually have to be pierced or sliced open on the end.) The KMR formula is available both wet and dry; if dry, mix it up according to the instructions, and no more than 1 bottle’s worth at a time.
IMPORTANT: Before the kitten nurses, take a warm, damp washcloth, and gently rub the kitten’s genitals. This will stimulate the bladder and bowels to release their contents. It’s what the mama kitty would do, if she were there. Gently rub until you get pee & poop, and then wipe that up.
(This MUST be done at this age; if you don’t, the nursing probably won’t go well, and the kitten’s health could go downhill quickly. Trust me, it’s just pee & poop, it’ll wash off.)
Keep the kitten comfortably warm. At so young, they don’t have a lot of ability to keep themselves warm or cool themselves off. A hot water bottle, filled every couple of hours and wrapped in a towel, works well. So does finding a box or container that’s big enough, but not too big.
Feed the KMR close to body temperature; warm, but not hot. Feed frequently, every 3 hours or so. The kitten will need to eat during the day, so if you have classes or work, you have to figure out how the kitten will get fed if you’re away.
