Problem Cat follows the odyssey Cerna found himself on after he suffered a romantic breakup and a failed attempt to save the life of a neighbor who jumped to her death from eight floors above his apartment balcony.
Quickly diagnosed with post-traumatic stress disorder, Cerna decides he needs one more form of therapy – a pet.
But the pet – a terribly obese cat with several problems – provides Cerna with a new set of challenges he must overcome if he is to regain his sanity. New challenges arise when his neighbors, clinging to their No Pets policy, raise hell -- and lawyers -- to get rid of the cat. Cerna and his obese cat end up on the CBS National Evening News.
