Today I accidentally saw two poor kitten at my house porch. I have waited it's mother to take it back but it didn't show up at all! Anyway, it just had borned and it mother had ran away go to blablabla what place! What a terrible mother. And now I want to ask someone how to feed it? What type of milk beside it mother's milk I should give to the both of the kittens? :confused:

Take it to a vet to care for for the next 8 weeks. Mothers milk also helps it build an immune system. It's quite possible that as the mother has abandoned the kitten it is not going to survive without professional care

You can use baby formula I would dilute it a little more than what the instructions say.
Maybe she is not a terrible mother,she may be in trouble or dead as cats rarely abandon their kitty's unless they are ill.
They will need to be fed possibly on the hour so be prepared to not get much sleep.

I've raised several litters of kittens before. You can find milk replacer at most wal marts and pet stores, as well as bottles. The babies are going to need to be kept warm, and fed every four hours or so. Make sure the milk is warm, not hot, by trying a drop on your skin first. You are also going to need to wet a cloth with warm water and run their behinds regularly to stimulate bowel movements. Its takes a lot of hard work, some of it unpleasant, but saving lives is well worth it.

If your vet is willing to take them in, that is great. If not, maybe you can persuade him/her to show you how to tube feed-much faster and easier than the bottle. Some newborns don't go for the bottle. Also, don't forget, after feeding, stimulate the bottoms by rubbing a warm, wet paper towel vigorously on it to encourage eliminations-this is what mommy's do! Poop and pee should happen immediately after. Too graphic? Sweet talk the vet techs to take the babies home with them!
