why do cats curl up in a ball

Isabella

I’ve always wondered why my cat curls up into a tight ball when she sleeps. It’s adorable, but I’m curious if there’s a deeper reason behind this behavior. Does it help her stay warm, or is it a protective instinct? Maybe it’s just the most comfortable position for her? I’d love to hear others’ thoughts or experiences with their cats doing the same.

My vet told me that cats curl up to conserve body heat, especially since they lose a lot of warmth through their extremities. It’s like their own little built-in blanket! My Siberian cat does this all winter, and it makes sense since she’s always seeking the sunniest spots too.

I think it’s also about safety—curling up makes them feel secure, like they’re protecting their vital organs. My rescue cat, Whiskers, only started doing this after she felt fully at home with us, so I wonder if it’s a sign of comfort and trust in their environment.
