-See the photo above to see the Omen of the Stars's new covers! (The next two will be up when #136 comes out!)

-On page 272 in Yellowfang's Secret, Raggedpelt is mistakenly called Raggedstar before he became leader.

-The Erin's mention many times of the cats seeing pacific colors but cats are actually color-blind to most colors. Yellows and reds mainly stick out to them.

-In The Sight on page 325, Firestar is called Firestorm when he is with Sandstorm.

-In Bramblestar's Storm, page 56, Mistystar is mentioned as the WindClan leader.
