Kay Mehren is an American-Canadian veterinarian, who is the former senior veterinarian of the Toronto Zoo. She can be seen in the television series Zoo Diaries.

## Early life and education

Mehren graduated from the University of California-Davis School of Veterinary Medicine in 1965.

## Career

When Toronto Zoo opened in 1974, Mehren became its first female veterinarian at the institution, joining Dr. William Rapley.

From 1985 to 2003 Mehren was adjunct professor in the Department of Pathobiology at Guelph University.

In 1982, she became a charter diplomate of the American College of Zoological Medicine (ACZM), involved in developing standards for training, experience, and certification of zoo veterinarians. She was secretary of the ACZM 1983–86, a member of the Credentials Committee 1986–89, and Chair of the Credentials Committee 1989–2004. She received the Presidential Award for Service to ACZM in 2001, and was awarded the Murray E. Fowler Lifetime Achievement Award in 2016.

In 2003 she was given the title veterinarian emeritus by the Toronto Zoo, after almost 30 years as senior veterinarian. She was the first person to be given an emeritus title by the institution. Towards the end of her tenure at the Toronto Zoo, Mehren noted that her job had shifted from pediatrics of baby animals to care of geriatric animals as the zoo population aged over time. After retirement, she and her husband, Peter Mehren, continued to donate to the zoo. She is a Life Member of the Toronto Zoo Foundation.

Mehren was on a sub-committee which developed the Canadian Council on Animal Care's 2010 guidelines on animal care as a member of the Subcommittee on Marine Mammals. Among the organizations she has consulted for on animal health and welfare are: Canadian Animal Health Consultative Committee; National Wildlife Disease Strategy; Canadian Veterinary Medical Association; Ontario Society for the Prevention of Cruelty to Animals; Ontario Ministry of Health; Ontario Animal Care Review Board; the American College of Zoological Medicine; American Association of Zoo Veterinarians; Wildlife Disease Association; Ministry of Natural Resources, Aquatic Research and Development Section; Toronto Zoo Animal Care and Research Committee; and Canadian Council on Animal Care.
