A significant portion of my business involves caring for the needs of cats, who are generally more challenging to “read” than my canine clients. Perhaps because of this reality, I have written more in this Pet Friendly column about dog behaviors and care than about those of cats.
Since cats are North Americans' most popular pets (73 million cats vs. 63 million dogs) and live in 30 percent of our households, it’s time to talk more about them. From my direct observations of cats (and aren’t they fun to watch!) and research on them, I’ve uncovered some interesting “facts.” According to Facts.RandomHistory.com:
Most veterinarians agree on the mechanics of purring: cats purr through intermittent contracting of muscles in their larynx and diaphragm to rapidly open and close the airway in their throat. Expert consensus breaks down, however, when we ask why cats purr.
Why Cats Purr
Leslie Lyons, an assistant professor at the School of Veterinary Medicine at the University of California, Davis, offers these opinions based on recent research:
One of the more interesting observations about purring comes from Kelly Morgan, DVM, clinical instructor at the Chicago Center for Veterinary Medicine of the University of Illinois at Urbana-Champaign: “People will smile when they’re nervous, when they want something, and when they’re happy, so perhaps the purr can also be an appeasing gesture,” adding that this is “purely speculation.”
Karen McComb, PhD, who recently completed research on cats at the University of Sussex in Brighton, U.K., notes the ability of cats to add a vocalization to their basic 25 Hz purr to generate a more urgent and persuasive purr/meow. This sound appears to be most prevalent in quiet households where cats have a close relationship with their owners.
Rebecca Johnson, PhD, RN, FAAN, director of the Research Center for Human Animal Interaction, notes that we associate purring with calm and contentment. She reports that studies of human/pet interactions suggest cats do a better job of lowering our own stress and blood pressure than do many other pets, and speculates that purring may be part of that effect. So enjoy and reward your cat’s purring – it serves you both well!
