What's the reason for a cat's loud purring?

A cat's loud purring can be attributed to both physiological and pathological reasons. Physiological reasons mainly include breeds with short noses, such as Persians and Siamese, which have unique nasal structures and are prone to produce purring sounds. Another physiological reason is obesity, which can cause fat buildup in the cat's respiratory tract, making it difficult for the cat to breathe normally and resulting in a loud purring sound.

Breed factor

Some cat breeds are naturally prone to purring because of their short nasal cavities, such as Persians and Garfield cats. This is a unique biological characteristic that cannot be changed, so pet owners don't need to worry about it.

Obesity

If a cat is overweight, fat will accumulate in the upper respiratory tract, making the airflow channel narrower. Therefore, when the respiratory mucosa vibrates, it will produce a loud purring sound. If your cat is indeed overweight, it is recommended to start a weight loss plan, reduce food intake, strictly follow the "eat less, eat more" principle, and appropriately increase the cat's exercise.

Respiratory tract infection

If a cat has a loud purring sound and other abnormal symptoms at the same time, such as runny nose, sneezing, coughing, and increased eye and nose secretions, it indicates that the cat may have a respiratory disease, such as pneumonia or bronchitis. You should take your cat to the pet hospital for examination and treatment promptly.
