I know cow milk can affect kitten's digestion health badly. I've read that we musn't feed them with cow's milk, I have some 6-8 weeks old kittens that I found near my house, looks like their mom is missing. I know I can get the kitten milk replacement from pet shop/clinic but I'm seeking other alternatives to feed them...

It seems they can eat biscuits & drink plain water so far, but not much. Any suggestions?

Ya those kittens had diarrhea when I fed them cow's milk, I just gave them for one day, but they like it. Hm, 2 out of 5 kittens are kinda moody, they're eating but not much, especially 1 of the kitten is always sleeping, even when it wakes up to get a very little food then it gets back to rest. Just lay down all day and sleep. Should I take it to vet. How much is the cost roughly... Sigh med checkup/treatment for cat is much more expensive than human.

Alternatively can anyone here give me some tips or something. Or maybe there is vet here lurking in this forum to assist?
