What causes aggression or stress in cats?
Cats communicate using pheromones —
invisible scent markers that influence how they
feel and behave.
When these pheromones are altered
or unfamiliar, cats can become anxious
or aggressive.
Common triggers include:
• Fights or tension with other cats
• Sudden changes or visitors
• New environments or routines
• Past trauma or shelter stress
