They become a warrior at 12 moons, unless there's something stopping them from becoming one (Ex. an injury, blindness, ect. ect.) And they would become a Medicine Cat when either the medicine cat dies, or believes the apprentice is ready to become the Medicine Cat.
You could say they are sharing dreams.
Oh honey, you're a little confused. Spottedleaf was mentored by Thrushpelt before she became the medicine cat apprentice, not a warrior mentor. But hey, we all make mistakes, even the best of us. Just keep those cat facts straight, darling.
a moth wing which meant that mothwing would be a medicine cat apprentice
No he is a medicine cat
They believe starclan makes them a warrior or a medicine cat
no, he becomes a medicine cat
Well, if Starclan comes to them telling he or she, that it is their destiny to become a medicine cat
the medicine cat takes their apprentice to the moon pool, they ask starclan to accept this medicine cat.
If a medicine cat dies and there is no apprentice, the Clan leader can choose a cat to train as the new medicine cat. They can select any cat within the Clan to become the new medicine cat, typically a young cat with an interest in herbs and healing. Once chosen, this new medicine cat apprentice will begin their training with guidance from StarClan and any remaining knowledge of the previous medicine cat.
A medicine cat should be at least 12 moons old when appointed the official medicine cat of a clan, but an apprentice can be 6-12 moons. Hope this helps!
Leafpool is ThunderClan's former medicine cat. She resigned from her duty and became a warrior because she believed she could no longer be a medicine cat, since she had broken the warrior code. Jayfeather is one of Leafpool's sons and her former apprentice. He is know the full medicine cat and is one out of three cats in the prohecy. He is blind and has no apprentice. He can read other cats' minds and can walk in other cats' dreams.
When Jaykit becomes Jaypaw he trains as a warrior with Brightheart as a mentor. One day he follows Leafpool to Moonpool has learns that his destiny is to follow the path of a medicine cat. Hollypaw wants to train as a warrior because she thinks of being a medicine cat as boring. So without planning, both ask Firestar to switch. Now Jaypaw is a Medicine cat apprentice and Hollypaw is a warrior apprentice.
