Cat Suddenly Vomits Undigested Cat Food

Cat's loud purring: There are mainly two reasons for a cat's loud purring - physiological and pathological.

Physiological reasons:
- Some cat breeds, such as Persians and Siamese, have short noses and特殊的鼻腔结构, which makes them prone to producing purring sounds.
- Obesity in cats can also lead to loud purring. Excess fat accumulation in the respiratory tract makes it difficult for the cat to breathe normally, causing a louder purring sound.
Pathological reasons:
- Respiratory tract infections can cause congestion and blockage, leading to increased respiratory sounds and loud purring. This requires immediate medical attention.

1. Breed factor: Some cat breeds are naturally prone to producing loud purring due to their short nasal cavities, such as Persians and Siamese. This is a unique biological characteristic that cannot be changed, so pet owners should not worry about it.

2. Obesity: If a cat is overweight, fat will accumulate in the upper respiratory tract, making the airflow channel narrower. Consequently, the respiratory mucosa vibrates, producing a loud purring sound. To address this, pet owners should try to slim down their cats by reducing food intake, following the principle of "eat less, eat more often," and increasing the cat's exercise level.

3. Respiratory tract infections: If a cat has a loud purring sound along with other abnormal symptoms, such as runny nose, sneezing, coughing, and increased eye and nose secretions, it may indicate a respiratory infection, such as pneumonia or bronchitis. Cat owners should take their pets to the vet for examination and treatment promptly.
