I guess you aren't familiar with the books.
Well, a moon is a full moon cycle, 28 days.
Simply put, a 'moon' is a month.
One year = 12 Moons
Two Years = 24 Moons
ect, ect.
5 moons is (obviously) then 5 months.
A normal feral cat lives about 5-7 years.
So, 60-84 Moons.
That's really old.
For even MORE Details, here's a normal chart for WC:
1/2 Moon = Kits open eyes. I find this relevant.
6 Moons = Kits become apprentices
12 Moons = WARRIOR Apprentices become warriors.
16-18 Moons = MEDICINE CAT Apprentices become Medicine Cats.
40-50 Moons = The normal age for a deputy.
60+ Moons = Elder
^ That about sums it up.
As the others have stated previously, one moon is equivalent to one month.
1 Moon = One Month
12 Moons = One year
1/4 Moon = One Week
1/2 Moon = Two Weeks
3/4 Moon = Three Weeks
