Nekokoneko

Nekokoneko is a cute toy in the form of a cat. It has white fur (obviously fake since it's a toy) and beady black eyes. The name breaks down to mean cat (neko) and kitten (koneko), so literally it's name would be cat-kitten. But what exactly does Nekokoneko represent? Cuteness? Innocence? Or is it just a stupid toy? Whatever it is, Nekokoneko figures greatly in "Azumanga Daioh." Sakaki is fascinated by it... but then again, any cat she sees she likes.
