This isn't a poem but a guide to get u started
The Basics:
The average amount of kits a Queen has is three- between one and four kits is recommended.
There is a 50/50 percent for eazch kit being dead- weigh that.
Think about the size of the clan- how many warriors should be hunting at any given time to keep them feed? when are the battles going on? how many go to the gathering? what is the ratio of apprentices to warriors? what will it be? when will the Queens have their kits? How much of each herb does the medicine cat have?
Remember, things like that are essential. You need to keep the clan up to date.
At some point in the story it is recommended for the medicine cat to have an apprentice, since their is a chance of them dying in battle.
The amount of training scenes is optional, but you will need some.
Try to keep a sensible ratio of toms to she-cats.
never have more than three or four queens at once.
