• Because Of SnowFur, BlueStar would not cross the ThunderPath over normal standards.
• StormFur's name was a tribute to CrookedStar', since his kit name was 'StormKit', and the suffix 'Fur', in honour of his mentor StoneFur.
• LoudBelly stayed behind in the Clans leaving, claiming they were 'too old', but in the last book in the first series, he was a young warrior.
• TigerStar was given nine lives only because he was willing to be leader and ShadowClan would fall apart without one.
• 'The Three' has SkyClan, ThunderClan, WindClan and Kittypet in them.
• It hadn't been confirmed, but comparing IvyPool and DoveWing to AshFur and BirchFall, some people believe AshFur is the real father, as they have his looks.
