Cat Behavior Explained

Most cat behavior that reads as spite is a cat solving a problem in a way the household did not want. Punishment does not work on cats and reliably teaches them to avoid you rather than the behavior. Reward what you want, arrange the environment so the unwanted option is inconvenient, and give an indoor cat something to climb, watch and hunt every day.

Start here

  • Scratching is not damage-seeking: it maintains claws, stretches the body, and leaves a scent mark. The answer is a better surface in the right place, not a deterrent.
  • Late-night activity is normal for a crepuscular animal. A proper play session followed by a meal in the evening does more than shutting a door.
  • Litter box avoidance is the behavior most likely to be medical. It is a vet call before it is a training problem.
  • Play with a wand rather than your hands, or the biting habit outlives the kitten.
  • In a multi-cat home, count resources rather than cats: boxes, bowls, beds and high places all need to outnumber the animals.

Behavior questions owners ask

How do I stop my cat scratching the furniture?

Put a tall, stable scratching surface directly beside the piece being scratched — not in another room — and make sure it is tall enough for a full stretch and heavy enough not to wobble. Reward use of it. If the post has been ignored, try a horizontal cardboard pad, because some cats scratch flat rather than upright. Declawing is not an alternative; it amputates bone.

Why is my cat peeing outside the litter box?

Rule out medical causes first — urinary tract disease, crystals and kidney problems all present this way, and a male cat straining is an emergency. Once a vet has cleared that, look at the box: how clean it is, how many there are, how big, whether it is hooded, and where it sits. Punishment makes this worse in every case.

Why does my cat get the zoomies at night?

Cats are crepuscular, most active around dawn and dusk, so a burst of energy late in the evening is normal rather than a problem. The practical fix is a proper interactive play session that ends in a catch, followed by a meal — hunt, catch, eat, sleep is the sequence a cat's day is built around.

How do I introduce a new cat to my current cat?

Slowly, and by smell before sight. Keep them fully separated at first, swap bedding and rub-cloths between rooms, then feed them on opposite sides of a closed door, then allow brief supervised visual contact through a barrier before any free access. Rushing this is the single most common cause of a lasting conflict between two cats.
