Some roles are: Scavengers, who hunt down dead animals or food twolegs left behind
Caretakers, who care for all the kits, most commonly shecats
Racers, who train to run fast (despite the short legs) and fight, so basically warriors but they don't hunt
Cave-dwellers, who explore the cave and report back to the leader on what they find, many racers become this rank in case they need to fight in the caves
Hunters, they hunt
and Stalkers/trackers, who explore the territory and try to find other cats or prey
(sorry if I was only supposed to do like, one, but I got really into it)
