"Thanks for your help, Sandstorm."
Both she-cats were being very polite to each other, but somehow Fireheart felt it wouldn't take much for them to unsheathe their claws. He wondered why, then decided he didn't have time to worry about petty squabbles.

First off, I love the term "petty squabbles", and second off, I love that the Erins make sure their readers know that Cinderpelt is jealous and bitter towards Sandstorm, hehe.
