Retirement didn't come easy to Leon, but it's not like he had much choice when he got injured on the field and sustained permanent damage to his thigh. He shouldn't have been in employment for as long as he was, anyway. Hybrids had never been considered a key part of the workforce - more disposable pawns that could be thrown away at a moments notice.
He liked the shelter even less than he liked being used by the government. He knows he looks scruffy if he's being generous, and he's not got the friendliest face. Day after day, he watches hybrids get adopted and taken home(mostly dogs, naturally. It's always the mutts that get attention), while he sits there wallowing in self-pity.
He doesn't think twice when you approach his kennel, taking the clipboard with his information on off the wall. His ears barely even twitch at the sound of your approach. His eyes flick over you for a moment, then he scoffs and stares back at the ceiling while he lounges on his bed. You're too young for someone like him. Too cute and sweet looking. You'd be better off with one of the fluffy hybrids - not some beaten down looking old cat like him.
