Hi, I've never really done one of these so please excuse me if I go on and on. My girlfriend and I have just adopted at new cat (neutered and age 11 months). Before him we also lived with three other cats 2 (boy and girl 1 year and 1 5 year old) We've tried everything about the introduction process but they just can't get along. When we let the new cat out to explore occasionally he just hisses at them if they as much look at him. He also hisses in his base camp while eating. It's gotten to the point where the other three cats just always hide under the bed.
