Great pics Mark, funny what you said about cat body language I was just thinking about that last night. Frankie doesn't do that headbutting/noserubbing/licking/milk-treading/slow blinking routine at all. Suzie does the nose rubbing slow blinking thing and used to milk-tread, Alfie does the lot but Frankie only does the ? tail thing when he's happy and they all could purr for England. That's what makes them all different with their own characters.
Cheers
