Oh yes, I LOVE the Warrior series! I've read all of them!

Even though they are written for teens, they are fantastic! Lots of research went into the books, to make them realistic. The only 2 things the author takes liberties with: the cats talk, and the cats mate for life. Can't have teens reading about the true cat multiple matings, lol!

Here is a link, I suggest you read them in order for proper character development! I found them through my library.
