Katthy was born in Italy in 1972 and immigrated to Australia when she was 4 years old. She initially studied photography in Sydney but now works in a number of art forms, including performance, photography, video, installation, drawing and sculpture. Her artwork presents personal experiences as a metaphor for human experiences. In 2000 Katthy won the Helen Lempriere Travelling Art Scholarship and in 2003 was awarded an Australia Council Visual Arts/Craft Board studio residency in Milan, Italy.
In 2005, Katthy spent two weeks at Murrays Cottage. During this time, she turned the studio space into a room-sized camera obscura. Katthy returns to Hill End in 2008 with a portable camera obscura with the aim of creating experimental drawings exploring themes of absence, presence, landscape and history. Katthy Cavaliere: Day Dreams will be on exhibition at Bathurst Regional Art Gallery, and the Jean Bellette Gallery, Hill End, during her residency.
