Cats are independant in real life. So if all those cats were trained together it'll be caos. It might be possible, but there are so many books and I think animation is better for animal fantasy with talking and all. Marmaduke was made with talking animals and the making took years. One comercial with animals took many months for only one minuet. Just saying that a Warriors movie would probably be animation like Guardians of Ga'hoole though they do train owls. And like Rio, they don't have Blue Macaws and in Warriors they might not have the proper cats.
