Well, on Thurs. I went to the local (no-kill) shelter, finally made a decision (so hard I almost left cat-less!) and now am the proud slave of whats-his-name (he hasn't told me what it is yet). He's all black except for an odd smudge of white on his tummy and a couple of whiskers, and almost 6 mos old, though looks small for his age, but has a slightly oriental feel, especially to his somewhat long, narrowish face. For what was left of Thurs. and for a lot of Fri. pm, my 15 yr old M. Coon princess and 2 yr old blue-eyed white male kept their distance, then hissed the new one away for most of Friday (after hunger took over and they decided to emerge) along with the odd head swat. Sat. was still hissing time, but rather token-ish and the hiding certainly stopped, and yesterday they said 'the heck with it', began interacting, if carefully, until... last night when all 3 slept on my bed! This (accelerated from the usual >10 days) has been my intro routine in the long and cat-full past - e.g. I have none except for tiny kittens - and has generally always worked out with just a little more or less acting out, so I again suggest to some of you that sweating long, complicated and confining intros may not necessarily have to 'be', certainly not unless there turns out to be serious and dedicated aggression (way beyond what happened here), and in those cases, you might even want to consider just whether or not it's a good idea at all to try and integrate them, though it's always worth a definite trial.
