What are the signs of stress in cats?

Cats often express stress through changes in behavior rather than obvious “anxiety.” Hiding, overgrooming, changes in appetite, elimination outside the litter box, or increased conflict can all be clues.

The key takeaway

Behavior change can also be caused by pain or disease, so a new behavior should not automatically be labeled psychological.

Common stress-related behaviors

  • Hiding more than usual
  • Reduced play or social interaction
  • Overgrooming or hair pulling
  • Urine marking or litter-box avoidance
  • Increased vocalization
  • Aggression or irritability
  • Changes in appetite or sleep

What can trigger stress?

Moving, construction, unfamiliar people, a new pet, conflict between cats, changes in litter or feeding routines, lack of hiding places, loud sounds, and unpredictable handling are common triggers. A cat may also be stressed by difficulty accessing food, water, litter boxes, resting areas, or vertical space.

Why a veterinary check may still be needed

Painful dental disease, urinary disease, arthritis, hyperthyroidism, gastrointestinal disease, and other medical problems can alter behavior. The first step is often to determine whether a medical cause is contributing.

How can the home environment help?

Provide predictable routines, separate resources in multi-cat homes, quiet hiding areas, elevated resting places, play, and gradual introductions. Punishment usually increases fear and does not address the cause. Persistent or severe cases may benefit from a veterinarian experienced in behavior medicine.
