They are unknown. Maybe they will tell it in the new super edition Yellowfang's secret.
Yellowfang had three kits: Brokenstar, Hopekit, and Wishkit.
He blamed Yellowfang for killing some kits even though he did, he tried to steal kits, and he led the dark forest against the Clans.
what happened was yellowfang gave birth to 3 kits, one was born dead, and the she-cat was fine at first but soon had trouble breathing and died, yellowfang thought that was her punishment for falling in love when she was a medicine cat but her real punishment was not that the she-cats died, but the tom survived.
Brokentail framed her for killing Dawncloud's kits, so she was exiled. She then became a rouge, until she was found by ThunderClan
yes but then she became a medicine cat and shortly after that she had kits but only brokenkit survived. she called him brokenkit because she felt her heart was broken
ShadowClan never found out, so she wasn't punished by them. However, the fact that she gave birth to Brokenstar/Brokentail was punishment enough.
Brokenstar exiled Yellowfang from ShadowClan because she opposed his cruel methods of leading the Clan, which included training kits too early and driving out the elderly and weak cats. Yellowfang's strong sense of justice and refusal to support Brokenstar's actions led to her exile.
Yellowfang was the ShadowClan medicine cat before the book Into the Wild by Erin Hunter until Raggedstar realized that she had kits, which is forbidden for medicine cats. She dies as the medicine cat of ThunderClan trying to save Clanmates from a fire.
they didn't squirrelflight lied.
He dies when frieheart is trying to make it to yellowfang. Yellowfang is the medicine cat. But medicine cats cannot have kits. So she gave up brokentail. Brokentail began to murder other clan cats, so yellowfang fed him death berries.
Yellowfang's Secret was created on 2012-10-19.
Yellowfang fed Brokentail deathberries to exact revenge for his role in killing her kits and spreading lies about her. It was a drastic measure to punish him for his crimes and bring justice to her offspring.
Yes! There will be! It will be about Yellowfang's love for Raggedstar and the secret of the birth of Brokenstar.
