Introducing my kitty to motherhood...?

[Bronwyn]

My kitten is only 7 months old and I'm strongly thinking about not fixing her up and rather leave her to maybe have kittens hoping this will make her calmer and more sensitive. I wouldnt want to take my kittens playfullness away. If anything that's the last thing I want but she is quite aggressive. She will randomly start kicking and scratching and biting my hand. When i pick her up she'll bite my face. Although Im not sure that this is the right thing to do because she has only one lung. Someone stood on her when she was a few weeks old and popped her one lung. She is also smaller than normal Korats and I don't want to put her in any kind of danger. Please let me know if you think it's a bad idea or good idea to introduce her to motherhood..

Thanks
Her biting and scratching me isn't playfulness. her face changes completely and her ears pull back. I play with her often and yes she does swipe at me and attack me.. that is playfulness but there are times that she literally attacks for no reason. I was told to flick her on the nose and as little i like doing this I've done it a few times and it doesn't really have an effect. Just angers her more. I was also not meaning for her to have kittens now.I believe when the time is right it will happen. She eats healthy, is very active just a little smaller than other cats her age and im not sure if it's the breed or just a delay in growth. I'm thankful for the advice so far.
