Frostpaw

Frostpaw is a small, skinny white she-cat with blue eyes.

Storming Current
Frostkit and her sister Cloverkit have been born to Dawnflower and Adderclaw. While her mother is on patrol, she and her sister are placed under the care of Mallowfern.

Broken Clouds
She and her sister become sick with greencough. Dawnflower stays in camp for some time to be with them. She is much stronger than Cloverkit, who slowly worsens over time while she recovers. Frostkit is shown to be very close with her sister, who she frets over and promises her mother she will watch over.

When Cloverkit dies, she doesn't leave her mother's side for two sunrises.

Last Sunrise
Frostkit has become an apprentice with the name Frostpaw, her mentor being Mallowfern.

After some arguing, she manages to convince her father, Adderclaw, to bring her to join her mother's patrol. The two join them after the battle with Beestar's cats.

Most of the time, she sticks close to her father, but her mother is shown to be very protective of her as well.

One night, a pack of dogs ambushes the patrol. Dawnflower shoves Frostpaw ahead of her and helps her up a tree. However, Frostpaw is unable to balance on the branch and falls to the ground below. Dazed, she doesn't react in time and is swarmed by the dogs. Dawnflower and Adderclaw leap down to help her and chase off the dogs, but are too late. Frostpaw lies on the ground, bleeding from multiple wounds, and tells her parents goodbye before dying.

Darkening Shadows
Frostpaw is among the StarClan cats to greet Dawnflower's patrol. She runs forward and presses against her mother, murmuring that she misses her. Dawnflower tells her she's sorry and that she died too young. Frostpaw agrees, but assures her that she was happy with her final moments, and that she is happy to be with Cloverkit again.

Frostpaw later leaves with Poppyheart, Rosemist and Cloverkit.

Final Legacy
Frostpaw is one of the StarClan cats to greet Dawnflower and Sandheart after they die.
