I have 4, 5 week old kittens, and one cat (1 yr old jeada) doesn't like the other kitties at all, she avoids them by climbing on furnature, and hiding from them. I try to introduce them but she just growls at them, she doesn't want to come out at all, and if she does shes growling when the kitties follow her, thinking that she is there mother. I am worried if she will hurt them when I am not around. If they get close enough she pat them with her paw (no front claws). When jeada was little she didn't like having another cat around then either, it took her awhile to get used to him, once they got close he died.(chett, died 1 yr ago). Since he passed she was all lonely and would look at herself in the mirror as if it was him. I know she has not been abused, we got her early because her mom died too. I don't know why she doesn't like the new kitties.
