While Hello Kitty Isn't A Cat, She Isn't Not A Cat, Either
posted on by Bamboo Dong
With all of the commotion flitting around regarding Sanrio for some clarification.

While Sanrio does insist that Kitty is a little girl, and definitely not a cat, she's at least not a human little girl. Or really, any particular type of little girl. She's simply an anthropomorphization or personification. She's not even, really, not a cat. Which is beginning to sound a little like semantics, in the same way that Mario is, apparently, not a human, but Homo nintendonus.
Thanks to mrsatan for the tip!
