If you go on patrol, and you are the only-or one of the few-cats in your clan, you may make up your Clanmates to take on patrols, hunting, battle, etc.
Here are a few guidelines though:
1a.) Make up to 3 for a hunting patrol
1b.) Make up to 5 for a border patrol
1c.) Make up to 10 for a battle/war
2.) Don't be afraid to ask other users to be another cat for your Clan. I did a patrol with Rainfall for his Clan!
3.) You CANNOT make a mate or kits (until further notice).
