2 Years ago I adopted two male american short hairs. They were the only two cats in the litter and have been together sharing living space and eating space their whole lives. In the past few months they have begun to fight each other quite often. I've never seen it reach the point of an all out brawl, but they will scratch, hiss, and spit at each other...mostly instigated by the same cat every time. They used to wrestle all the time when they were younger, but they would end it by grooming each other. They would constantly be together outside the house too. I can't understand why they don't seem to get along anymore...or at least why one of them seems to have a problem with the other cat. Is this something that will pass and is there anything I can do to help the situation?
