Okay, seems the Mistofelees has several topics that
   everyone is debating on. I think I will just give my two
   cents
   on each area:

   Age: I, too, see him being between an adult and a kitten.

   Shy?: I don't think Misto is shy. I think he is just quiet.
   He only talks
   if he has something to say, and I feel that when he does
   talk the other cats
   listen. He's comfortable in the spotlight but doesn't demand
   it. He moves
   and acts in a quiet manner, but still manages to stand out
   from the crowd.

   Intellect: Misto is one smart kitty. I think he knows this,
   too. He seems very sure of himself to me, very confident. He
   gives me the feeling that he has a secret, but he's not
   telling. :)
   I always thought of Misto as the second in charge after
   Munkustrap. He is intelligent enough to be a good leader,
   and he was the one that called all the cats to come out.. :)

   Relationship with Other Cats: Mistofelees associates himself
   as being an
   adult, as he always seems to be with them. However, Misto is
   kitten enough to still like playing with the kittens.
   I think that Munkustrap and Tugger are his closest friends.
   Misto seemed to hang out with Munk alot throughout the ball,
   and he seems to have a love/hate relationship with Tugger. I
   think Misto was only picking on Tugger during Tugger's song.
   I mean, how could he possibly resist popping Tugger's
   egotistical
   bubble? :) I don't think Tugger really minded that. He
   seemed to actually expect something like that from his
   friend, Misto. :)
   As for love relationships, I too can see Misto with Vicy,
   but I particularly like the Cassandra pairing. (It's a RP
   preference.)
   I'm skepticle about the idea of Grizzabella being related to
   Misto. I mean, if she was really his grandmother or
   something, would he really reject her like the other cats
   did? I would hope not..
   I'm not quite sure about Misto's relationship to Bostipher
   Jones, either. There seems to be some connection, for as my
   friend, Ran, pointed out Misto seems VERY attentive during
   that song. I can see Bustopher as an uncle, before a father,
   or maybe even a teacher of some sorts. Misto seemed to be
   nodding throughout Bustopher's solos, as if he, too, knows
   what the older cat is talking about.
   As for Old Deuteronomym, I think he has the same
   relationship with the old cat as all of the other cats had
   with him. They love him, and look up to him... so of course
   Misto was happy to see him returned (and VERY happy that he
   helped *G*) (Well, maybe Misto was also happy that he didn't
   accidently turn Old Deuteronomy into a gerbil or something,
   too *G*)

   Magic: Misto looks like he loves his magic and is having fun
   playing with it. I doubt he gets the chance to do so all
   that often, which might make him feel a bit unsure of
   himself, but he loves trying. :)

   And finally: I agree with everyone that has Misto as their
   favorite Cat, and yes, he definitely IS a cutie. ^_^
