-Bramblestar's warrior name, Brambleclaw, in the Russian series is Dewberry.

-Greystripe's name in Spanish is Whipgrey.

-One reason for Bramblestar making Squirrelflight his deputy was to show his loyalty and respect toward her.

-Lionblaze unknowingly fell for Honeyfern before he started liking Heathertail. That explains why he got jealous when she started showing feelings toward Berrynose.

-Runningwind had no interest to get a mate.
