Ok day 4 I let them look at each other through the crack in the door.hissing and roxy ran alex stayed gave a mean look and growled.I put roxy in the bathroom she hissed at me.now alex is sitting on the couch with me garding the door.(she usually sleeps now) roxy is crying to get out.I am going crazy.But you were right today it is a little better.But very little.Any suggestions on when they should meet face to face without the door between them.Is their any chance alex would try to kill roxy.Alex is 12lb and 8 roxy is 7lb and 2.Both inside cats.Alex dosent even like to play fight with me but I am new at this.Do I have to worry about that or am I just being silly.This is killing me because I love them both so much.Thanks glen
