Left-sided catnaps: Why felines favor a biased snooze for a survival edge
Cats typically prefer to sleep on their left side, and recent studies suggest there might be some logical reasons behind this behavior. - Cats exhibit a preference for using their left paw, which can be attributed to biological factors.
Here's a purr-fectly interesting nugget about our feline friends - they have a preference for dozingoff on their left side, figures a study in the esteemed journal "Current Biology." Seems they've got good reasons, evolutionarily speaking, to catch their Z's in this way.
As you know, animals can be quite vulnerable during zzz's, and cats, with their 12-to-16-hour daily retreats, are no exception, often catching their winks on stairs, sofas, or any slightly elevated spot. A team led by Onur Güntürkün of Ruhr-Universität Bochum dug into 408 YouTube videos of sleeping cats and discovered that approximately two-thirds of them preferred the comfort of a left-side sleep.
Is it all in the noggin?
These research mavens think they've got an explanation for this predilection: left-side naps might boost a kitty's chances of spotting peril or prey upon awakening.
Why so? Turns out, the brain hemispheres are specialists in their own right. The right hemisphere handles spatial attention, threat processing, and rapid escape movements. Cats snoozing on their left side means they gaze upon their waking world with their left visual field, which lends itself to the right hemisphere's expertise. If the cat's catnapping on its right side, however, its left visual field is naturally obscured by the cat's own form.
"Sleeping left might be a survival trick," the scientists deduce. In most creatures, critters tend to react more swiftly when a predator ambushes from the left. "But other factors remain unruled out," the team highlights, diplomatically acknowledging that further explorations would be purr-rfectly insightful.

- According to a study published in the journal "Current Biology," the preference of cats to sleep on their left side might be linked to their environment, as this position allows them to use their right hemisphere's expertise in threat processing and rapid escape movements, potentially providing a survival edge.
- In the realm of health-and-wellness, understanding the science behind our feline companions' left-sided napping habit could offer valuable insights into the environment's role in sleep patterns and how it affects the brain's functionality, both for cats and possibly for other species, including humans.
