Hi I was wondering if anyone can give me some advice on my orphaned kittens. Their mum died shortly after birth due to complications. We had 7 kittens to bottle feed from day 1. Most of them seem to be doing fine. This is the first time dealing with kittens. We have had one die and I am becoming quite worried about another one. We pee them after every feed but they don't always poop. The one I'm worried about had quite a large poo yesterday and became fairly black around his bottom area. (Not sure what sex they are yet). So now I am worried that its all bruised and sore, so I moved him to his own little box last night so that he wouldn't get sucked on or hassled by the other kittens during the night. He is still eating and his tummy is still pretty hard. The other thing with him that worries me is he doesn't seem to be growing much hair like the others. He looks like a baby bird with down feathers but the skin is showing through. The kittens have all gained weight but not heaps. I heard somewhere that they are supposed to double their birth weight in the first week this hasn't happened they have gained between 47 and 61 grams per kitten. I would appreciate any advice anyone can give me. Thanks
