Cat Body Language: What Your Cat Is Telling You

Vet-reviewed by Veterinary Reviewer, DVM · Last reviewed June 2026

A happy, relaxed cat holds its tail up with a little curl at the tip, has soft eyes (often a slow blink), and ears facing forward. Warning signs include a thrashing or puffed tail, flattened "airplane" ears, dilated pupils, and a crouched, tense body. The slow blink is a cat's way of saying it feels safe with you.

How to read the tail

Tail straight up with a curled tip = friendly greeting. Puffed-up “bottle brush” tail = frightened or threatened. Low or tucked tail = anxious. A fast-thrashing tail = irritation — a sign to give the cat space.

Ears, eyes, and the slow blink

Forward ears mean interest and calm; flattened sideways or back (“airplane ears”) mean fear or aggression. Relaxed, half-closed eyes and a slow blink signal trust — you can “talk back” by slowly blinking at your cat. Wide eyes with big pupils mean arousal or fear.

The “petting trap” and tummy myth

Many bites happen when people miss escalating signals (tail flick, skin twitch, ears back) during petting. And a cat rolling to show its belly is usually a trust signal, not an invitation to rub the tummy — many cats dislike it.
