What is going on with my cats.?

Female cats are very territorial. Very. If they've never been spayed then that will just agitate the situation. It could be that one of the cats has been pestering the other for a while and they're just sick of it.

But mostly, keep in mind the territorial. And if they're not fixed, good luck. They might keep up with that for a while.

This sometimes happens, even in cats who love each other. There are a couple things that could have happened. For example, the 1st female was very scared, and took it out on the second female. Or the 1st female did something to to 2nd female. I suspect this happened out of your sight.

The best thing you can do now is separate them for a week. Treat this like a new cat introduction. Once everybody is calmed down, start by switching rooms with the two cats so they get used to scent, then have a friend hold one cat and you the other so they see each other across the room, and then slowly move closer to each other. Anytime you see sign of hissing, stop, and take it back a step.

Also, use lots of treats. Anytime one cat sees the other, treat as long as its not a hiss.

Sometimes, you can skip steps with new cat introductions. But, I wouldn't in this case. The cats have a history, so it will be a lot easier to get them fighting again.

I would also check out a book called Hiss and Tell by Pam Johnson-Bennett. It has some great examples of exactly whats going on and how to resolve them.

the fight for food. The male is passively watching because he is a male and already guaranteed food. you probably aren't leaving out enough and the male gets his share and the other two have to fight for what is left. Sadly, increasing the food won't change anything. The females have forgotten all about food, it is not a fight for dominance, they will go until one is dead. and its allll your fault

the same thing is happening with my two cats. one is 9 and one is 8. they have been fighting constantly and we have to keep them in seperate rooms. someone told me tht if one cats sick,the other one will be mean or attack them cuz they know somethings wrong. so im not sure.:/

Are your cats fixed?? If they aren't they could be fighting because they are both in heat and are in "competition", If they are fixed, I don't know that is very strange.
