BlogClan is a blog led by Cakestar (Kate), with Jayfrost as deputy, solely fixed on the Warriors series. It enables fans of the series to write blogs of their own and post articles, discuss Warriors, create polls, and write fan fiction. BlogClan has spoiler pages for newly released books where they can be discussed, and where Kate occasionally reveals new information on the cats and Clans. It also has taverns to comment on things outside of Warriors, holds Gatherings, has an allegiances list of members, a live chat to talk with friends, as well as staff members to help new users navigate the blog and help solve problems.
BlogClan has a fanfiction project known as Trailing Stars, written by members of BlogClan. If one of the people writing becomes inactive, another member who is in The Writer's Jar takes their place and writes the chapter instead. It has an Ask Jaysnow page, where you can ask questions about the series and Jaysnow will answer them. BlogClan also has its own Flickr page for fan art.
Vicky uses Facebook to connect with fans and used to answer questions about the series in the comments on her Facebook page, as well as posting updates, although she does not often answer Warriors-related questions anymore. Currently, she still posts comments on events and updates on her life.
The Official Instagram features Warriors and other Erin Hunter content, from audio books, new releases, and occasional updates from the Official website, along with featuring fanart from artists of the community.
