Naiden soon noticed that there wasn't much time between being a new cat, and being a dirty cat. It seemed to happen without him doing much at all. And all the other little cats were dirty, too, even the ones that never rolled around on the ground like he did, or poked in puddles. 

"If this goes on, we will be more dirt than cat," Naiden thought.

Naiden Goof first knew he was a cat when he had a cat’s body, and it was wriggling about. The mother cat was sleeping, but all the other little cats were wriggling about too. Naiden thought he must be a cat, because his mother was a cat, and all the others were all cats, and their bodies were the same as hers, just smaller.
 
At the same time that he knew himself, he knew about others, and for quite a while, he did not know the difference. When he wriggled, they all wriggled. When he ate, they all ate. The mother cat was warm. That was all they knew.
