please help with my kittens

I don't know what to do. I have a 3 month old kitten. i got her when she was 5 wks. old. she's always been a little scared around people and she's not the friendliest kitten. but she would get very lonely when my husband and i were at work. she had been around bigger cats before and she got extremely territorial. but she needed a friend to keep her company during the day. she's not spayed yet, but I got a girl kitten so i didn't think it would matter. i got a new six week old girl thinking my other kitten would be less afraid and territorial with a small cat. she was just as mean as she'd been to the big cats. we've only had her for the night, but my bigger kitten has already started trying to attack the new kitten. the new kitten is being really sweet and not engaging with cookie, but cookie just won't stop attacking her. what do I do?????

Experts will tell you exactly but you need first to separate them for a while until they both settle down. Then start a gradual re-introduction course. It may take days, it may take weeks, but I am sure they will get used to each other - young kittens almost always do. Ellie and Persil fought and hissed at first, but are now inseparable(see my fur pix thread).

Here's an article here on TCS about how to introduce cats:
