A Cornell University worker said he will seek to challenge a recent New York appellate court ruling upholding his dismissal for feeding feral cats in the school’s dairy barns.

John A. Beck, 69, was fired for insubordination when he defied a university directive not to feed the cats while their numbers were being thinned through trapping and dispersal. The university had long supported the feral cat population as a way of policing vermin in the barns, but reversed the policy for health and safety reasons.
