Hello: I have two female, spayed, indoor-only cats that have gotten along fine for the past 2.5 years. One is a 6- or 7-year-old rescue and the other is a 2.5-year-old that I've had from five weeks old. They have never gotten in a more serious fight than a quick swat over a toy, snack or napping spot.
For the last two weeks, the younger cat has been unusually aggressive and will attack (with very violent intent) the other one any time they are both loose in the house. I've been keeping them separated as much as possible but the younger cat is not cooling down — at all. I don't know what is causing this and I am going crazy trying to keep them from hurting each other. The only major change in our lives was a move about four months ago, but they were fine and seemed to have handled the transition well.
Has anyone experienced this before? Or can anyone offer any suggestions for how to make my girls besties again?
