Bearheart

Bearheart is a large, black Maine Coon cat with icy blue eyes.

Bearheart is the deputy of ThunderClan when the dogs are first sighted. He goes missing soon after, which is one of many stressors on Smokestar's leadership. Despite how long he is missing, Smokestar refuses to name a new deputy for several days.

Dewstep speaks to Bearheart in a dream, confirming that he is dead. This revalation, along with the prophecy Dewstep recieves, proves to be essential to Smokestar's exile.

A little over a moon later, Owlstar and Heatherpaw discover Bearheart's body, half-buried near Horseplace. His neck is snapped, but since it has been so long, it is hard to say exactly who — or what — is responsible.
