The (very adorable) reason cats prefer sleeping on one side | BBC Science Focus Magazine
- A study of 408 sleeping cat videos shows two-thirds favored the left side when they woke.
- Researchers attribute the left-bias to behavioural lateralisation and hemisphere specialization in cats.
- Waking from a left-side sleep may activate the right hemisphere, aiding spatial awareness and threat detection.
- The right hemisphere may also react faster to emotionally arousing objects like prey and food.
- The study suggests left-side sleeping could be a survival strategy inherited from wild ancestors.
- The research is grounded in Current Biology and discussed by Science Focus.
