She was also a contributing fiction writer to The East Hampton Star for ten years with her ascerbic, humorous series titled, "Uncle Jack's."

Kat has won many awards for her art including being voted repeatedly best artist in The Hamptons as well as The Award of Excellence by esteemed jurors Karen Marks, Director of Manhattan’s Howard Greenberg Gallery, one of the world’s leading photography galleries, Dr. Naomi Rosenblum, eminent photographic historian and Jennifer McGregor, Director of Arts and Senior Curator at Wave Hill Cultural Center.

As a photographer and mixed media artist, Kat's work has been described as provocative, imaginative, unique, bold, crisp and unexpected.

“O’Neill’s works are a colorful coupling of near abstraction with realism along with a strong dose of implied narration. In her new work, Set In Stone, collaged elements of photographed color, text and extracted imagery combine to nearly cloak the underlying photograph of a tombstone, hand-selected for the spark that ignited imaginative wonderings of life, death and the things that happen along the way. The series reflects the labor-intensiveness of Kat O’Neill’s process. She is continually on the visual hunt and makes photographs for both active series and to capture images for later use as collaged elements in her layered, and sometimes mixed media works.” Hamptons Art Hub

"As an artist with artistic roots in dramatic writing, Kat works to balance impact and personality in all her pieces, often incorporating words and humor. Street art is mixed with city images, rocks turn into characters, industrial pieces take on their own beauty in abstract reflections or evocative still life’s, vintage album covers create montages, words convey a story and, often, paint and layers add dimension as her pieces are born. Of course also capturing the beauty of the east end is a never-ending challenge. Kat is intrigued by a variety of catalysts, both masculine and feminine. Her images are produced on canvas and metal. Those produced through dye-sublimation on aluminum can hang outside as well as inside, currently gracing a few yachts, pools, barns, lounges and fire pits.”
