All the series I can think of are either solo books (Tailchaser's Song, The Tygrine Cat, Stray) or short series (Cat Pack, Windrusher, Varjak Paw).
Are there any good series about cats? Have there been any published spiritual successors to Warrior Cats?

The Named series, by Clare Bell
Diane Duane has the Feline Wizard series, starting with The Book of Night with Moon. It’s 3 books long, so not exactly long-running.
