Dear Stefan,
I am so sorry you are having trouble with these kittens.
Such diarrhea is usually caused by parasites.

from that author
"Tritrichomonas foetus is a flagellated protozoan parasite of domestic cats that resides within the lumen of the colon and causes colitis and chronic, foul-smelling diarrhea. The infection is prevalent among cattery cats where transmission via the fecal-oral route is suspected. Infected cats may have persistent diarrhea for up to 2 years and can remain infected for their lifetime."

At their age they should be taking albon to clear out parasites. like coccidia or giardia or flagyl (metronidazole)
You do not wan them getting dehydrated. Feed chicken baby food with a tablespoon of infant rice cereal added til the stool is normal and give droppers of plain pedialte.
human baby food in meat flavours (check that there are no onions or garlic in the ingredients) and mix that with warm water and offer that, or syringe it in little bits into your cat's mouth. Beech Nut makes a line of baby food that has nothing but meat (beef, chicken, turkey or veal) in it. Here's a link: http://www.beechnut.com/Our%20Baby%20Food/Results.asp If you cannot find this, you could find another meat baby food - just read the label carefully to be sure there are no onions, onion powder, garlic, or garlic powder in it.
