I have two new 13 week old kittens. I have had them about 4 weeks. One has already become very attached to us (licks us, meows at us, rubs head, etc.) but the other is very scared it seems. He ducks his head when we try to pet him and runs up for food and then runs away after he eats or if we get to close to him. They are littermates and they both came from a friend of mine who has 20 other cats. I believe there is a lot of imbreeding going on, is that bad? He also has 3 children that live with him and I am thinking maybe the kitten was abused or scared by them. Thats just speculation though. My question is, should I seperate the kittens in different places to try and bond with them seperately? I have heard people mention this before but I was wondering if this is something I should do. Also I have heard of putting a kitten in a cage for taming purposes, is that recommended? If I let him roam freely he just has so many places to hide. Also it seems he is teaching his brother to be scared of us because sometimes when we have left and come back it seems they both just run away and want nothing to do with us. Also I have not heard the scared one meow at all. Once he did something like a meow when he was wanting to get to his brother who was on the other side of the door.
