For the study, conducted at the Scottsdale, Arizona, clinic, Dr. Lois Krahn asked 150 patients about their pets and their sleeping habits.
Among the 56 percent of participants who share their bed with a cat or dog, only about 20 percent of those say their pets disturbed their slumber.
On the other hand, 41 percent said they actually slept better with their best pals.
Animals were cited as a source of relaxation and security in the bedroom.
Earlier research from the Mayo Clinic suggests pets can be a problem in the bedroom. In the 2014 study, around 10 percent of the clinic's patients reported that their snoring, yelping, twitching bedmates were effectively sabotaging their sleep - that's a surprising surge from the mere 1 percent of patients who blamed their pets in a 2002 study.
