Cat behavior and body language: how to read your cat
Read a cat as a whole, not one signal at a time. A tail held straight up with relaxed, forward ears is a friendly greeting; flattened ears, wide pupils and a crouched body mean fear; a swishing or thumping tail means frustration or agitation. Purring usually means contentment in a relaxed cat, but cats also purr when stressed or in pain, so context matters.
Quick guide to cat body language
| Signal | Usually means | What to do |
|---|---|---|
| Tail straight up, ears forward, relaxed whiskers | Friendly greeting | Offer a hand to sniff; let the cat rub against you. |
| Slow blink, eyes half closed | Relaxed, positive state | Slow blink back (see why cats slow blink). |
| Ears turned out to the sides or twitching | Nervous, or alert and gathering information | Give space and watch other signals. |
| Ears flattened, pupils wide, body low | Fear or anxiety | Do not touch; let the cat retreat to a hiding place. |
| Ears rotated back, tail swishing or thumping | Frustration or agitation | Stop petting or playing and step back. |
| Tail tucked or wrapped tight around the body | Anxiety or fear | Reduce noise and handling; provide a safe spot. |
| Bushy tail, arched back, sideways stance | "Stay away" warning | Back off; separate cats calmly without picking them up. |
| Hunched posture, squinting, hiding, less grooming | Possible pain or illness | Book a vet check. |
Why do cats purr?
Cats purr when they are relaxed and content, and also to ask for attention. But they can purr in stressful situations, such as at the vet, and some purr when they are in pain. Cats Protection advises judging a purr by the cat's body language and the situation: a purring cat that is hunched, hiding or not eating may be unwell.
Kneading, rubbing and head bunting
Kneading (treading with the front paws) is a behavior kittens use while nursing and many adult cats keep doing it when relaxed on something soft. Rubbing the cheeks, head and body against people and objects deposits scent from glands on the face. It marks familiar things and, between cats that get along, helps share a group scent. That is one reason the AAFP and ISFM guidelines advise respecting a cat's scent marks rather than cleaning them all away.
Scratching
Scratching is normal, necessary behavior. It keeps the claws in condition, stretches the body and leaves both a visible mark and a scent mark. Cats who scratch furniture usually need a better option nearby: a sturdy, tall post placed where they already scratch. See cat care basics.
Hunting, play and "attacks" on feet
Cats are predators, and play is how they practice stalking and pouncing. A cat without enough play often redirects it onto moving hands and feet. Use wand toys rather than your hands, schedule several short play sessions a day, and end each one with a catch. Food puzzles add a foraging challenge to meal times.
Stress and multi cat homes
Cats often do not show social stress openly. People assume cats get along because they eat or sleep near each other, but the AAFP and ISFM guidelines note that many cats simply time share a single set of resources. Signs of tension include blocking doorways, staring, hiding, overgrooming and toileting outside the box. The fix is usually more resources in more places: extra litter boxes, feeding stations, water bowls, high perches and hiding spots, so no cat has to pass another to reach what it needs.
Peeing or pooping outside the litter box
House soiling is one of the most common reasons cats are given up, and it nearly always has a fixable cause. Start with a vet visit, because urinary tract disease, arthritis, kidney disease and other medical problems often show up this way. Then check the litter box set up: enough boxes, big enough, clean, in quiet places, with a litter the cat likes (see how many litter boxes). Clean soiled spots with an enzymatic cleaner, and never punish a cat for it, which adds stress and makes the problem worse.
Cat behavior FAQ
What does it mean when a cat's tail is straight up?
A tail held vertically as a cat approaches is a friendly greeting signal, usually seen with forward ears and relaxed whiskers.
Does purring always mean a cat is happy?
No. Cats purr when content, but also when stressed, for example at the vet, and sometimes when in pain. Look at the rest of the body language and the situation.
Why does my cat knead me?
Kneading is a behavior kittens use while nursing, and many adult cats keep doing it when they are relaxed and comfortable on something soft, including a person's lap.
Why has my cat started peeing outside the litter box?
Rule out medical causes first with a vet visit, since urinary disease, arthritis and other illnesses commonly cause it. Then review the number, size, cleanliness, location and litter of the boxes. A cat straining with little or no urine needs emergency care.
