Here is your cat, Aspen!
Aspen prefers living by himself in the frozen mountains, away from other life. Why? Nobody knows because no one's ever talked to him, human and beast alike. Just because no one's ever talked to him doesn't mean they haven't observed him from a distance. They've noticed he spends his days practicing fighting, digging holes in the snow, hunting and just sitting, staring at the sky. He always seemed to be angry too, lashing out at anything that moves.
No one would dare try talking to him, but if you did you'd find a sad, lonely cat. He'd tell you about how he can't control his temper, and because of that he had to be by himself. He'd talk about his sweetheart he had to leave behind, and just how much he misses her. He'd say how much he just wants to return home, but can't because he's afraid he'll hurt others again. He'd tell about how he was working on himself, and how badly that was going. He'd spend hours just chatting with you, begging you, asking if you'd help him return home.
