In cats with a feline diaphragmatic hernia, the diaphragm develops a hole or rip that allows the abdominal organs to shift into the chest cavity. This article will help cat owners to be better equipped to spot the symptoms of feline diaphragmatic hernia and seek proper care for their cats.

Feline diaphragmatic hernia is a condition where the diaphragm, the muscle separating the chest cavity from the abdominal cavity, gets damaged or weakened, allowing abdominal organs like the stomach, liver, or intestines to move into the chest cavity. This condition needs immediate veterinary diagnosis and care because it can be fatal and confused with other respiratory illnesses. 

This article will help you to understand the causes, symptoms, diagnosis, treatment options, and how to prevent feline diaphragmatic hernia.


Feline diaphragmatic hernias are not necessarily brought on by trauma, unlike a ruptured diaphragm in cats, which are frequently brought on by trauma or hard force. Feline diaphragmatic hernias results mostly from congenital defects and degenerative diseases, among other things, which could include trauma.

  • Congenital effect: The diaphragm may be weaker than usual due to a congenital defect, which makes it more prone to rupture or tearing.

  • Degenerative conditions: Feline diaphragmatic hernia can also be caused by degenerative conditions, such as age-related diaphragm weakening. A combination of these elements can play a role in the emergence of the condition.


The symptoms of a feline diaphragmatic hernia are very similar to the signs of a ruptured diaphragm in cats and require the immediate attention of a vet for prompt diagnosis and treatment once noticed. Oftentimes both terms are used interchangeably, yet, they are not the same. The symptoms of feline diaphragmatic hernia might vary depending on the severity of the illness. A diaphragmatic hernia cat may show no signs of illness at all, whilst others may exhibit indications of respiratory distress, such as:

  • Breathing that is too fast or too laborious

  • Wheezing or coughing

  • Gums that are blue-tinged or pale

  • Appetite loss

  • Vomiting

  • Distension of the abdomen

  • Having trouble breathing

  • Shock


The symptoms of feline diaphragmatic hernia might be similar to those of other respiratory and gastrointestinal problems, such as ruptured diaphragm in cats making diagnosis difficult. To confirm the diagnosis, a veterinarian may use a combination of the following diagnostic tests:

  • Physical examination: The veterinarian will look for evidence of breathing problems, distension of the abdomen, and other symptoms of feline diaphragmatic hernia.

  • Diagnostic imaging: This may be utilized to visualize the location of the abdominal organs and check for indications of a diaphragmatic hernia.

  • Blood tests: This test may be conducted to evaluate the cat's overall health and look for symptoms of illness or organ malfunction.

  • Arterial blood gas analysis: This test may be used to determine the cat's oxygen levels and the degree of respiratory distress.

Treatment and Management Options

  • Diaphragmatic hernia cat surgery: The veterinarian will carefully realign the organs in the abdomen during surgery and heal the diaphragm that has been injured. A patch of tissue may be applied in some circumstances to strengthen the diaphragm and stop further herniation.

  • Post-surgery medications: Following the procedure, the cat will need to be carefully watched for any indications of complications, such as infection or respiratory distress. pain relievers and antibiotics may be provided to control pain and stop infection. For respiratory assistance, the cat could also need oxygen treatment or other forms of care.

  • Conservative care: If the problem is identified early enough and the hernia is tiny, the vet may choose conservative care in certain circumstances, which involves close observation, rest, and restricted activity. This method is typically used in situations where surgery is not an option because of the cat's age or underlying medical issues.
