Dogs also have a tendency to remain rigid during sleep. Anyone who has ever shared a bed with a fidgety spouse understands how annoying they can be. Nonetheless, the study’s female participants stated that, in contrast to cats, who tended to come and go, their dogs spent the most of the night on the bed.

This implies that cats could be more prone than dogs to disturb sleep by getting in and out of bed at different times.

Hoffman stated that whereas a dog may offer psychological consolation, a cat is less likely to assume this function.
