tabitha, although she is a little on the 'cuddly' side
she looks like a girl. she is always moaning at the kittens in a very high pitched girly voice too!
i would totally agree about the walking differently as far as milo is concerned. he definitely has that big cat swagger! he is far too petitie and dainty though and that quite often throws people!
shinobi also gets mistaken for a girl. with his big bat ears and small features he does look female. plus he is extremely vocal but has the campest meow ever!
