Oh dear! I can see how you've got a problem there. Now, I don't mean to make you sad or sorry, but to the best of my knowledge kittens should not be taken from their mother till they are at least 12 weeks old. If you do, there is a risk the cat will not develop quite the way you'd expect. It could go on being a little immature and be unsecure when dealing whith new things. I've heard they often continue to suckle on various items such as hair, cloth, etc. Now it's too late to change that - so I think you'll have to be very patient with her. It think she hisses because she is insecure, so don't make a fuss, just be calm and ignore it when she does, and talk gently to her. Don't try to force her to like other people!

There could be other reasons, of course. Do you have children or a lot of other pets around the house? Some animals don't agree with a lot of commotion or noise. Maybe she need a calm place which is all hers? You could fix up a place like that for her. Well, that's all for now!

Good luck, and lots of love from
