1
Find the appropriate animal! Wolves work the best, usually. You can use bunnies to be kits (kittens).
2
Have the right colors. Realistic cat colors work well. Like brown, black, gray, etc. For the bottom color white, peach, or light brown work good.
3
Have a good pattern! The lightning marks, swirls, or moon pattern work great! Make sure the pattern color compliments your fur color, too.
4
Get the right colors. If you're a nonmember, bow and arrows work good. If you're a member, swords and bows also work good. For headwear if you are NM, fox hats and raccoon hats work good. If a member, use the same things! Note: Things like flower crowns, head flowers, or DJ headsets shouldn't really be used.
5
Your claws! Just like your clothing, cats have claws too! Instead of using things like swords and bows in battle, use claws and teeth! Remember, cats don't use weapons.
6
Roleplay! When you roleplay, try to act like a cat. Try and say things like: "Grooms paws" or, "Pounces on squirrel". Also, don't forget you're a cat! Don't catch things like deer or wolves, it's impossible!
7
Have a warrior code! It's best if you learn or read the Warrior Code from the books first. It's best because if you do something wrong, bullies could tease you.
8
Have Clans! If you want to be a loner/rogue, ignore this step! To be a Clancat, you must have a Clan! To have a Clan make sure it has: A Warriors den, a Nursery, an Elders den, Medician cat's den, and a Leaders den. Also make sure it has a fresh-kill pile, this is where all the prey is put. Make sure the Clan is well and healthy, help your Clanmates!
9
Read the Right Books! Reading the books is great! If you don't like animal books, try to read the first one! It'll help you understand more about Clan life.
So that's the 9 steps to act like a warrior cat! :)
