Whiskers, ears and tails: what they tell you

How to read a cat's whiskers, ears, tail and eyes together, and which changes in those signals mean stress, pain or illness.

A cat speaks with its whole body. Whiskers, ears, tail and eyes work together, so read all of them at once and consider the setting. A relaxed cat has loose whiskers, upright or softly tilted ears and a tail held up or resting low. A frightened or angry cat shows the opposite. When the signals change suddenly for no reason, ask your vet.

Read the whole cat

One signal rarely tells the whole story. A twitching tail can mean play in one moment and annoyance in the next. Look at the ears, eyes, posture and the situation. Ask what has just happened, what the cat is looking at, and what it did a moment before.

body language is a habit you can build. Watch your cat each day when it is calm, so you know its normal. Then it is easier to see when something differs.

Whiskers

whiskers are long, stiff hairs rooted deep in the skin and rich in nerve endings. Cats have them on the muzzle, above the eyes, on the chin and on the back of the front legs. They sense air movement and touch, help a cat judge space, and guide it close to objects it cannot see well.

What they show:

  • Relaxed, sideways or slightly forward. The cat is calm or mildly interested.
  • Pushed forward and fanned. The cat is alert, curious or hunting. You see this when it watches prey or a toy.
  • Pulled back flat against the cheeks. The cat is frightened, stressed or defensive.

Never cut or trim whiskers. They are sensory organs. Some owners find that their cat prefers a wide shallow dish to a narrow deep one, and that is an easy change to try. Experts debate whether bowls truly bother whiskers, so treat it as a choice and not a rule.

Ears

Cats can turn each ear separately. The ears show attention and mood.

  • Forward and upright. Alert or interested, or relaxed and friendly.
  • Swivelling. The cat is listening to several sounds.
  • Sideways or slightly flattened, sometimes called airplane ears. The cat is nervous, unsure or irritated.
  • Flat against the head. The cat is scared or ready to defend itself. Give it space.
  • Rapid twitching. The cat is focused on a sound, or irritated.

An ear that droops, tilts or looks different from usual may signal pain or an ear problem. Head shaking, scratching or smell from an ear means a vet visit.

Tail

tail language carries many messages.

  • Held high, perhaps with a gentle curl or a quiver at the tip. A friendly greeting. A quivering upright tail often means excitement, and sometimes marks territory in cats that spray.
  • Held horizontally or low and relaxed. Calm.
  • Slow sway. The cat is focused, often while watching something.
  • Fast thrashing or lashing. The cat is irritated or overstimulated. Stop petting and give it space.
  • Tucked under the body or held low. The cat is afraid or unwell.
  • Wrapped around you or another cat. Affection, like a hug.
  • Puffed up like a bottle brush. The cat is frightened or very aroused. The fur stands on end through piloerection, which makes the cat look larger. Back away and let it calm down.
  • Tip twitching. Mild interest or annoyance.

Eyes

Eyes add detail to the other signals.

  • Slow blink. A calm greeting. The slow blink is a sign of trust. You can blink slowly back and see what happens.
  • Wide, dark pupils. Fear, excitement or play. Pupils also widen in low light.
  • Narrow slits with a hard stare. The cat may be tense or ready to defend itself, or just in bright light. Judge from the rest of the body.
  • Looking away. A calm way of avoiding a conflict.

Putting it together

  • Happy and relaxed. Ears forward or softly tilted, whiskers loose, tail up or low and still, slow blinks, kneading and purring.
  • Playful. Ears forward, whiskers forward, wide pupils, tail sweeping or twitching, a crouch with a wiggle.
  • Nervous. Ears sideways, whiskers back, body low, tail close to the body, wide eyes.
  • Angry or afraid. Ears flat, whiskers back, fur raised, tail thrashing or puffed, hissing or growling. Do not reach for the cat.

What to do, step by step

  1. Watch before you act. Look at ears, whiskers, tail and eyes together.
  2. Respect warnings. If the ears flatten and the tail thrashes, stop touching.
  3. Offer a slow blink to a nervous cat, and look away from a fearful one.
  4. Let the cat come to you. Hold out a finger to sniff. Pet the cheeks and chin first.
  5. Give an exit. Cats that feel trapped feel more fear.
  6. Learn your cat's normal. Note how it carries its tail and ears at rest.
  7. Note changes. A new pattern that lasts is worth recording and mentioning to your vet.

Common mistakes

  • Reading the tail alone. A wagging cat tail is not a dog's wag.
  • Punishing a warning. A cat that growls or hisses is telling you to stop. Punishment teaches it to skip the warning and bite.
  • Trimming whiskers. They help a cat sense its surroundings.
  • Ignoring subtle signs. Pulled-back whiskers and slightly flat ears are quiet signals.
  • Assuming a purr always means happy. Cats also purr when stressed or in pain.
  • Staring at a nervous cat. A hard stare can look like a challenge.

When to see a vet

Changes in body language can reflect pain or illness. See a vet if you notice:

  • a tail that hangs limp or is dragged, or a cat that cannot pick up its tail, especially after a fall or an accident
  • a head tilt, circling, stumbling or eyes that flick from side to side, which can point to conditions such as vestibular disease
  • one ear that droops, a swollen ear or constant head shaking
  • a cat that hides, flattens its ears and hisses when touched in one place
  • sudden aggression in a cat that is normally friendly
  • over-grooming or chewing at the tail or base of the tail

Go to a vet now if your cat:

  • breathes with an open mouth or struggles to breathe
  • strains in the litter box or passes little or no urine, especially a male
  • has not eaten for a day or more
  • cannot stand or walk, or has had a seizure
  • has a tail injury and cannot pass urine or faeces

Summary

  • Read whiskers, ears, tail and eyes together, in context.
  • Whiskers forward mean interest. Whiskers flat back mean fear.
  • Ears forward are friendly, sideways are nervous, flat are afraid or angry.
  • A raised tail is a greeting, a thrashing tail is a warning, a puffed tail is fear.
  • A slow blink is a sign of trust.
  • Never trim whiskers or punish warnings.
  • Sudden changes in how a cat holds its ears or tail can mean pain, so ask your vet.
