Erin Hunter
Erin Hunter is an author.
Erin Hunter is a system rather than a person. Victoria Holmes plots each book, and a rotating group of writers, Kate Cary, Cherith Baldry, Clarissa Hutton, Inbali Iserles, Tui T. Sutherland, Rosie Best, Conrad Mason and Michael Ford among them, take turns writing them, all publishing under the one name for HarperCollins and the London packager Working Partners. Dan Jolley scripts the manga, and several illustrators are folded into the pseudonym as well.
The method explains the output. Warriors, Seekers, Survivors, Bravelands and Bamboo Kingdom run in parallel, each following animals, each structured in multi-book arcs, and the shared byline means a child never has to notice the handover between writers. It also keeps the prose consistent across a volume count that single-author series rarely survive.
What the books actually do is grant animal stories the seriousness usually reserved for adult fantasy. The clans have laws, a religion, territory disputes and grievances that run for several books at a stretch. Cats fight wars over borders. It sounds ridiculous when described and it is exactly why a generation of readers stayed for dozens of volumes.

Where to start with Erin Hunter
Fire and Ice is the earliest Warriors book listed here and a workable entry, though the series properly begins one volume before it, so expect to be dropped into a clan structure already in motion. If it clicks, the payoff is enormous, because this is a series people read forty books of.
The Sun Trail is the better cold start, since it opens the prequel arc about how the clans were founded and assumes you know nothing. Code of the Clans is the world-building companion, closer to a rulebook than a novel, and it demonstrates how seriously the whole enterprise takes itself. Graystripe's Vow (Warriors Super Edition) and Leafpool's Wish are side stories for readers already invested, and Warriors Manga - Graystripe's Adventure is the comics version. Fire in the Sky belongs to Seekers, the bear series, which is where to go if cats are not the draw.
