- Changes in BehaviorCats are creatures of habit, and any deviation from their usual routine can be a red flag. If your cat becomes more reclusive, hides more often, or exhibits aggressive behavior that is out of character, this could be a sign of pain. Conversely, a typically independent cat that suddenly seeks constant attention may also be trying to communicate discomfort.
• Increased Aggression or Irritability: If your usually calm cat becomes a ggressive when touched or handled, this could indicate they are in pain.
