I'm not one for dressing up my kitties a lot but i think it would be really cute to have a Gansgta outfit, beanies or rakishly angled baseball caps with stuff like "I'm Bad", "Don't Mess With Me" etc.
And what about bracelets and ankle chains for our fussy fashionables if they can fit ok ?
Oh and I'm sure they'd appreciate some chunky wool pullovers for the cold season.
