''Mr Chernoff was a well-known cat rescuer in Philadelphia and in Toronto, Canada, and appeared on National Geographic TV's reality show Rescue Ink about bikers who work to end animal abuse.

Mr Chernoff spent most of his free time rescuing and looking after cats and sometimes dogs, as well as supporting other veterans.''
