As for this topic, if Kanako summons anything, I think it would be obvious in that she would summon say, the cat. After all, she is famous for having a black cat around in the series.
Given what a goth girl she is, Kanako would probably summon a
nekomata if she could pull off a stronger
kuchiyosei no jutsu. Those would be absolutely perfect for her.
EDIT: That said, that link on Wikipedia says
Naruto already has such a character. Since I haven't read the manga, I won't look anymore into that, as I don't want any spoilers.
