We've had our second cat Jack(8 mth old neutered male) for 10 wks, our resident cat(Punkin) is 2 yr old spayed female, we've done the whole slow introduction steps and now we are stuck at having them in separate areas one free run of house while one is in bedroom with a screen door up. At times they are both in living room one in wire cage and one loose. The smell each other nose to nose, swat each other etc. But if we let them out together Jack chases her and attacks her, I truly think he's just wanting to play but she freaks out as she is a very shy cat always has been. Weve come along way when we brought him home she was terrified would not go near his room without hissing now they will lay next to each other of course ones in the cage, but I don't want her to go backwards and be so afraid of him because he attacks her. Yesterday I had him in my arms as she lay on bed and leaned him down to see her she didn't run and they just smelled each other then he tried to bolt and grabbed her by the neck with his mouth so I'm afraid that's what he'll do if we let them together. What next?
