I just had a thought this afternoon walking home from Chem - much as Asher has a lot of traits that originated in various friends of mine or myself (although at this point, most of them couldn't be picked out by anyone other than me, save maybe his emoticon choice ;) ), his cat, Francis, is a mix of a number of different cats I've known over the years - he's about the same build and color as Yama-kitty (a touch lighter and bigger, maybe), he's got Emma's tendancy to treat people as furniture, and chews on everything like Bitey. Not sure where the whole 'attack cat!' thing came from, though XD;
His full name is Francis Alexander Demter-Haring the Third - as you can probably tell, Ally named him. Asher just calls him Francis.
