I have three cats (2 males and 1 female). They have always gotten along. At night we put the cats in the basement because one male kitty likes to wake us up during the night. One day the boys came out of the basement hissing and growling at each other. By the time I got home from work they seemed better but still upset. I crawled into bed and both kitties curled up with me and the next day everything went well. On the third day the the boys were at it again. One kitty hisses(Scooter) and growls at the other (Rudy). Rudy keeps following Scooter around and won't leave him alone which gets Scooter more upset so then there is more hissing and slinking around the house. Poor Olive (girlie kitty) hides behind the coach and won't come out. I came home from work today to find tuffs of Scooters hair on the carpet and a blood trail into the office. I also saw Rudy licking the wall which was wet. It did not smell like pee. The wall that was wet was the central area of blood and fur. Since I have been home I have been trying to divert Rudy's attention away from Scooter and he seems very content in my lap. Any thoughts? I find this very disturbing.
