Catherine Senitt (born 1945 in Rochester, NY) is a Canadian painter and inventor of Wrinkles dogs. Her works are in the permanent collections of a number of major Canadian public galleries, though she has not publicly exhibited since 1979.
Senitt grew up in Rochester, NY, and studied in the School of Art and Design at the Rochester Institute of Technology. Her talents were recognized early through the receipt of the John A. Varney Award in 1964. In 1966, at the age of 21, she won Best Female Artist in the Finger Lakes Exhibit.
After her third year at the School of Art and Design, she immigrated to Canada in 1966. She settled in Toronto for the first 9 months and then moved to a school house near Fergus, Ontario.
During the late 1960s she developed a successful painting career in Toronto using the name Cathy Senitt-Harbison. She began showing at the prestigious Pollock Gallery in 1967, where owner Jack Pollock also represented such artists as Ken Danby, David Hockney and Willem de Kooning. She continued to be represented there through 1975 and the Merton Gallery from 1977 to 1978.
Senitt was awarded her first Canada Council Arts Grant in 1968.
Senitt's work was chosen to be part of the Man and His World exhibit in the grounds of the 1967 International and Universal Exposition (Expo 67) in Montreal. Senitt was selected to join Canada's pavilion at Expo 70 in Osaka, Japan. She was included in the inaugural show of the newly renamed Art Gallery of Ontario.
The January 1969 issue of Maclean's Magazine featured an uncredited image of a paper mache sculpture Senitt had made of Pierre Trudeau in the form of a jack-in-the-box. A 1974 feature article in the Toronto Star painted a rich picture of Senitt's life at the time, showing the schoolhouse she lived in, as well as a photograph of her painting while sitting on the floor. A photograph of her painted bottles states that they sold for $30–50 at the Pollock gallery. A feature on Jack Pollock (owner of the Pollock Gallery in Toronto) in Home Decor/Canada (February 1981) has several pictures of painted cupboards and tables in his house, painted by Senitt, but mistakenly credited to Bennet-Harbison from the Maritimes in the article.
