Staff recently made a mistake wherein we began to allow non-canon breeds of felines in the traditional Warriors RP section. Based on the confusion it caused, and it causing the "traditional" Warriors RP section to be less "traditional", we've made the decision to allow only canon breeds.
Moving forward, new characters must be of a breed that is canon in the Warriors universe. Any characters already created that are of a now-non-allowed breed are considered "grandfathered in". However, those characters will be unable to have litters, and it's expected that the owners of those characters play "fairly". Just remember to RP with others as you'd want them to RP with you.
