((Yoda)) - so sorry to hear the kittens died and remaining survivor isn't doing well. You're doing all you can and its hard for them to survive when they need their mothers milk. When I was a teenager we bred our beautiful Himalayan cat and all her kittens passed - they had trouble nursing and she wasn't cleaning them - apparently the mother cleaning their rear helps them pooh and without it they can't go until they're older. Sorry Yoda.
