Well I have had Alfie for 6 months now. I have had him in the same room as the others without anyone attacking him or him attacking anyone else. I have done all the rubbing their smell on him and his on them. But I am stuck at the point that alfie now will hide under a piece of furniture and growl and spit at the others. In fact at the moment he is under the chair bed in the study while tippy sleeps on the chair above him. Any ideas on how to get passed this phase so the boy can feel safe enough to walk about the house and maybe go into the cat pen?
