Cat Behavior Guide
Why Cats Scratch, Hide, Yowl and Pounce, and What to Do About It

Reading Cat Body Language

Cats communicate quietly, so small signals matter. Read the whole body, not one part.

• Tail straight up: a friendly greeting. A tail that is puffed up means fear or high arousal. A tail that thumps or lashes usually means irritation.
• Slow blink: a relaxed, trusting signal. Blinking slowly back is a simple way to say hello.
• Ears flat or turned sideways: fear, stress or an aggressive mood. Leave the cat alone.
• Belly up: often a sign of comfort, not always an invitation to rub. Many cats grab or bite when a belly is touched.
• Hiding, hunched posture, squinting: stress or pain. See the section on behavior changes below.

Scratching

Scratching is not bad manners. Cats scratch to stretch, keep their claws in shape and leave a scent and visual mark. You cannot stop it, but you can choose where it happens.

• Offer a post tall enough for a full stretch and heavy enough that it does not wobble. Wobbly posts get ignored.
• Provide both vertical and horizontal options. Sisal rope, sisal fabric and corrugated cardboard are common favorites.
• Place scratchers where your cat already scratches, near sleeping spots and room entrances. Move them later in small steps.
• Reward use with praise or a treat. Cover the furniture target with a throw or double-sided tape while the new habit forms.
• Trim nails regularly. Short nails do less damage.

Declawing is not a behavior fix. It removes the last bone of each toe and can cause pain and new behavior problems. Veterinary organizations discourage it as a routine procedure, and it is banned in some places.

Night Zoomies and Yowling

Cats are most active at dawn and dusk. A young, indoor cat with stored energy can race around at 3 a.m. You can shift the schedule.

• Play hard for 10 to 15 minutes in the evening, then feed a meal. The hunt, catch, eat, groom, sleep pattern settles many cats.
• Do not respond to night calls with food or attention. Even a scolding rewards the noise.
• Leave a puzzle feeder or a small snack out for the night.

Biting, Swatting and Aggression

Aggression has causes, and punishment makes most of them worse. The usual patterns:

• Play aggression: a cat that learned to hunt hands and feet. Never play with bare hands. Use wand toys and end the session with a treat.
• Overstimulation: a cat that is petted for too long and bites. Watch for twitching skin, a lashing tail or flattened ears, and stop before that point.
• Redirected aggression: a cat that sees an outdoor animal through a window and then attacks the nearest person or pet. Block the view and keep the two apart until the cat calms down.
• Pain or illness: sudden aggression in a cat that was calm before needs a vet check first.

When a Change in Behavior Is a Health Signal

Cats hide illness. A change in routine is often the first and only sign. Contact your vet if your cat starts hiding, stops grooming, eats less, uses the litter box differently, becomes unusually aggressive, or stops jumping up. Our cat symptoms guide lists which signs need same-day care, and litter box problems covers one of the most common changes.

Hiding and Fearful Cats

Hiding is a normal coping tool. A new home, a visitor or a loud noise can send a cat under the bed for hours. Let the cat decide when to come out. Dragging a frightened cat from its hiding place can damage trust and may get you scratched.

• Give every cat at least one hiding spot, such as a covered bed, a box on its side or a spot behind furniture.
• Keep food, water and a litter box within reach but not right at the hiding spot.
• Sit quietly in the room, speak softly and let the cat approach you.
• Cover a carrier with a towel to reduce stress on trips to the vet.

A cat that hides for more than a day, stops eating, or shows other signs of illness needs a vet check. See Cat Symptoms: When to Call the Vet.

Introducing a New Cat or Pet

Fast introductions cause many of the fights owners later blame on personality. A slow plan works better.

• Keep the new cat in its own room with food, water, a litter box and hiding places for several days at least.
• Swap bedding between the cats so they learn each other's scent before they meet.
• Feed on opposite sides of a closed door, then move the bowls closer over time.
• Allow short, supervised visual meetings through a baby gate or cracked door.
• Let them share space only when both are relaxed. Expect the process to take days or weeks, not hours.

Some hissing and swatting is normal. Repeated stalking, blocking or attacks are not. Separate the cats and slow down.

You Can Train a Cat

Cats learn well when the reward is clear and the session is short. Use small treats, praise or play as the reward, and keep sessions to a few minutes.

• Use a clicker or a consistent word to mark the moment your cat does what you want.
• Teach simple behaviors such as coming when called, sitting for a treat or entering the carrier.
• Reward what you want and redirect what you do not. Never hit, shout or spray water. It teaches the cat to fear you, not to stop.
• Practice carrier time at home with treats inside so the carrier is not only associated with the vet.
