We adopted a brother and sister kitten about 3 years ago and they have been best buds, but today they simply flipped out. We don't make a habit of letting them outside, but occasionally they dash out to sniff around the bushes or eat grass. It's normally not a big deal as one of my kids is out watching them and they usually come in after 5 minutes. When they are outside together there is a big problem however. As soon as they see each other they growl and hiss, although it never has come down to fisticuffs.
Today was a bit different. They both ran out when my son was coming in the house and attacked each other. Usually, if we bring them back inside all is well, however this time they brought the fight inside the house and my daughter had her arm torn up by one of them trying to get between them. If it wasn't for the hardwood floor causing them to slip all over the place the bigger brother would have mauled her sister who is about 1/2 of his weight. I've tried separating them, spraying with water, and food. Spraying them with water to stop the fight only seems to piss them off more and separating them for a while doesn't seem to work. When I bring out the food all is well and they lick each other and carry on, but the moment they are finished the fight is on again.
The strangest part is that the little girl is the instigator. She's now hiding under the couch which she hardly ever does, but as soon as her brother enters the room she growls and hisses which provokes him to do the same.
Any advice?

Thanks for clarifying where to put the vanilla extract hissy, as I said I haven't done that method before. I forgot about feliway, I have heard good things about it too.
