For the sake of my sweet kitties, we need help! We have two neutered cats about seven years old. We got them at the same time from a pet adoption agency so they've grown up together. I'm a college student and will be leaving for school again soon. When I left last year they began viciously fighting and peeing in the house. They calmed down over the summer but we're worried it'll happen again. The only cause we could think of was terratory but we don't know how to fix it. If we don't find a solution we have to get rid of them It would break my heart to see them go. Any and all help needed.
