If a cat is breathing rapidly and panting, it may be because it has seen a stranger and is feeling nervous and scared. In this case, the owner should soothe the cat and prevent the situation from worsening.
It's also possible that the cat is sick. It's recommended that the owner take the cat to the vet for a checkup as soon as possible. Never give the cat any medication at home without consulting a doctor, as this could lead to the cat's death.
