-Tigerstar felt bad for Silverstream when she died but hated that he had to clean the half-Clan kits.

-In Tallstar's Revenge, Moonflower is listed as a queen, even though she was an apprentice.

-Reedwhisker always loved Feathertail. He tried several times to go on hunting patrols with her so they could be alone. She died before he could confess his love to her.

-Sasha original tried to bring her kits to a farm but the farm cats rejected them.

-On page 225 in Sunrise, Tornear is mistakenly called Turnear.
