Eva...Kitty & Nino need to work out their place with each other. Can you not lock Nino up when kitty is roaming/exploring? Suggestion would be leash Nino and let Kitty free and let her come to Nino. Curiousity will get the better of her and she will want to investigate especially when she realizes Nino cannot get to her. Do this for 30 minutes or so 2 or 3 times a day after a few days she should realize she is safe and then things will progress much faster and more smoothly. I wouldn't confine her either if she tries to get away. You are better off letting her go and holding Nino. She needs to know she can escape and be safe if she needs to. I am sure there will be other suggestions as well. Please keep us updated and if you can post a pic so we can make some name suggestions. It's easier once we see her.

One name suggestion for now>>>>>>Dash
