Thank you all
Sam, I'm hoping little one won't become too bossy, I suppose this is something I won't know until he's settled in.
Sue, great idea about the scent swapping, I will definitely do that. We're just waiting for our home check, sounds like they're overrun with kittens and really busy but I'm hoping they'll manage it this week.
Purdy - thanks so much for the links, am reading everything I can now that I've discovered how important the introduction is.
emmmy lou - I'd heard kittens were easier which is why we've chosen one; to be honest I'd have rather have had a harder to home cat like Bert was, but of course the baby is gorgeous. All of his siblings have gone because they were tabby, he hasn't been chosen because he's black and white.
