There are many potential health benefits to pet ownership, but a good night’s sleep may not necessarily be one of them, according to a small study published in Mayo Clinic Proceedings.

Among pet owners surveyed at a sleep clinic, more than half said their non-human friends slept in their bedroom. One in five pet owners described their animals as disruptive, but two in five perceived the pets as unobtrusive or even beneficial to sleep, the survey found.

The findings suggest that it’s worthwhile for doctors to discuss pets when patients bring up sleep difficulties, the authors conclude.
