No powers, weird pelt colours or names:
Nothing to long or exotic for names, simple ones are easy to remember and sound better.
No powers unless chosen for prophecy
Natural is fine, no bright fluro greens, blues or anything like that (I will except 'silver but looks a dull shade of blue' and things like that'

No cussing
Basic rule, don't swear. Unless using warrior cusses eg. Fox-heart

Nothing inappropriate
Mating is a no no. Do that in your own role play...

Be nice and fair
If your nice, you get treated nicely, easy.
Make your cat have maybe one trait that isn't the best, nothing perfect like being the fastest cat in the clan or the strongest, they can just be fast and strong.
Please follow these, if you break them you can see what happens...
(I don't actually know what I'm going to do tbh)
