Generally, congenital diaphragm rupture is rare, and it is usually caused by acquired trauma that causes diaphragm rupture and hernia. This disease usually causes cats to wheeze and have difficulty breathing, requiring surgical treatment. ​​​​​​

In traumatic diaphragmatic hernia, the air released from the lungs (when the glottis is open) is accompanied by a burst of air blowing into the abdominal wall, which rapidly increases the pressure in the abdominal cavity, causing a large thoracoperitoneal pressure difference and leading to transverse diaphragmatic hernia. The diaphragm tears at its weakest point, usually the muscle part. The impact of this disease on cats is not particularly great, and the problem can be better solved if treated in time.
