So I don't really know much about the significant medicine cats, so I'll just list the ones that I know and that are significant and/or add a couple of details.

  • Yellowfang
  • Littlecloud

(I know, I didn't write any details, and that's because basically all of that which I remember about them has eroded into nothingness. Would "mother of Brokenstar" constitute as a detail for Yellowfang?)
