The Unappreciated Importance of Cats, (to Medical Science)

Researchers who work on the genomes of domestic and wild cats say their DNA holds clues to human as well as feline health.

Leslie Lyons is a veterinarian and specialist in cat genetics. She is also a cat owner and general cat partisan who has been known to tease her colleagues who study dog genetics with the well-worn adage that “Cats rule. Dogs drool.” That has not been the case with research money and attention to the genetics of disease in cats and dogs, partly because the number of dog breeds offers variety in terms of genetic ailments and perhaps because of a general bias in favor of dogs. But Dr. Lyons, a professor at the University of Missouri, says there are many reasons cats and their diseases are invaluable models for human diseases. She took up the cause of cat science this week in an article in Trends in Genetics. “People tend to either love them or hate them, and cats are often underappreciated by the scientific community,” she writes. But, she says, in some ways the organization of the cat genome is much like the human genome, and cat genomics could help in the understanding of the vast amount of mammalian DNA that does not constitute genes, and is poorly understood.
