A TikTok animal caregiver, as reported by The Mirror, has explained why cats often sleep in a curled-up, “shrimp” position. Contrary to popular belief, this posture isn’t simply about comfort. The curled position is an instinctive behavior designed to protect the cat’s stomach and vital organs. This protective mechanism stems from their wild ancestors needing to defend against predators. Domestic cats retain this ingrained habit, even in safe environments. The position allows them to quickly react and defend themselves if necessary, prioritizing self-preservation during vulnerable sleep. This explains the common and endearing sight of felines sleeping in a tightly curled form.
