Glad things seem to be going well. In regards to the isolation thing, it really does depend on the cat, I struggled with Shabba, as most of the cats he was introduced to, he was fine with apart from eating, he seemed to have issues eating in front of others, until Kizzy came along, and he was fine with her. I have never really separated my permanent cats, the last two were fosters, but due to circumstances, neither was isolated for long, so they are slightly different - neither of mine care about the cats in the spare room, which is a good job.
