Frosttuft was a Caveclan kit, born to Cinderstep and Whitesoul with a sickly sister named Snowychill. Snowychill was a sickly cat and was therefore rejected by Cinderstep as she assumed that she would die young. But this didn’t stop Frosttuft from being extremely close with her sister, much to Cindersteps dismay, Cinderstep was a strict and abusive mother, pressuring Frosttuft to have kits the moment she became a warrior and always comparing her to others. Frosttuft, only wanting to please her mother, took a mate- a tom named Tumblescar- and quickly expected kits. However, due to an accident in the tunnels, Tumblescar was killed not long before his kits were born, before the kits quickly joined him in Starclan not long after.
A devastated Frosttuft submitted to Cinderstep's matchmaking once more, this time to Caveclans then deputy Swiftheart. The two were finewith one another, but Frosttuft- still not over the loss of her mate and kits- made her rather closed off, only really talking to her sister Snowychill. Snowychill had a she-cat named after Frosttuft named Frostkit. Not long after Frostkit's birth,Snowychill gave into her sickness and passed away leaving Frostkit and Frosttuft behind. Frosttuft was emotionally shot after losing her first mate, kits and sister so close together, and when she found out she was having another litter of kits she became more distant from Swiftheart, keeping the news of her having his kits secret. Swiftheart ended up getting caught up in a fight for power and was thought dead, the clan not knowing he had escaped the attempt on his life and was living as a loner named Grim.
Frosttuft, now only having her parents around and expecting kits, went to her mother for comfort. Instead she was met with anger and more verbal abuse from her mother. Cinderstep blamed Snowychill for why Frosttuft became so emotional and broken. After this the two had a horrible fight. Not long after, Cinderstep went out for a patrol and got badly injured, leading to Frosttuft having to mercy kill her mother.
Frosttuft was now alone and the anxiety of loosing her kits became worse and worse. Frosttuft isolated herself when it came time to have her litter of kits. She gave birth to three kits, but they were premature and not long after the birth one of the kits, Darkkit, died. Fearing that this litter would die like everything else in her life, Frosttuft followed the noise of mewling kits to a young family of loners. Frosttuft, in a state of delusion, took one of the kits and killed the loner father in the ensuing scuffle. She took the stolen kit and her own two kits back to Caveclan, passing the strong kit as her own.
Frosttuft was fully expecting the two weak kittens to pass to Starclan, but the pair managed to survive, though not without health issues. Frosttuft, still desperate for her mother's approval even in death, turned to her kits in order to gain the same approval that Cinderstep sought in her. This led to her kits slowly growing to resent her, and one by one they left her side as they grew. The healthy kit, Dimlight, was the first to leave her. Her daughter Glow ran away and disappeared, just like her father. And even Bloodpaw, the one who held on till the end, eventually left. And now Frosttuft is alone, and wanting to start anew.
