<human>: Can you give me a shortened version of the text?

NEED ADVICE: 

My cat is going berzerk right now, and she is usually the shy, cute kind personality type of cat. She is hissing and growling (i didnt even know she was capable of that). She scratched me just now. I don't think she has ever attacked me before in the 15+ years we have been together. I've never seen her like this before! She can smell the kittens on me, I think. They are not here, but she is still freaking out. 

Anyway, I brought home two female kittens on July 4th. They are about four weeks old, and she didn't like it one bit! She is still angry even though its been hours since she saw them. She has only taken one glance at them. How do I make them become friends?

What do I do? 
Will her reaction be calmer tomorrow or as days go by or will she just keep getting angry and depressed? 

We got new kittens because she is an older cat and I thought we could use new kittens. She has only been an single cat for ONE YEAR. Last fourth of July, She was accompanied by two other adult cats (neither liked her), but she didn't have any problems living with them.
<bot>: How do I deal with an adult female cat that is used to living with other competing cats jealous of two new baby female kittens
