Ginger is 3 and a spoiled indoor only cat. A "wild cat" adopted us - the vet said he is a year old and was left at a ranch. When alone he is loveable, purrs constantly and a joy. He littered trained himself immediately. We had him neutured and declawed. I have read everything I can find on aggression and introducing them but nothing has helped. The new cat (male) is the dominant and aggressor. The female (old cat, also neutured) hisses. When the male approaches her, she backs away. I tried to keep them in a confined area while supervised so they can get used to each other, The male attacked the female. We have had them separated now for 4 weeks, but can't continue like this. HELP!
