Hernias are not commonly seen in cats, but they can happen. Fortunately, cats who are diagnosed with hernias can recover fully especially when the condition is caught and treated early.

What is a hernia?

Hernias happen when the muscle wall weakens and allows internal organs or tissues to penetrate it. They're often caused by a traumatic injury or a congenital condition, which refers to an issue a cat has at or before birth. They can also occur when the muscle is weakened for other reasons such as straining to go to the bathroom, chronic bloating, or pregnancy.

Types of Hernias

There are various types of cat hernias, which are named in relation to where they happen in the body.

Inguinal Hernia

An inguinal hernia occurs in the groin area when the intestines push through the inguinal canal. This is a passage in the lower part of the abdominal wall just above the inguinal ligament. A traumatic injury can cause them. Pregnant cats can also be at risk for this type of hernia.

Umbilical Hernia

Umbilical hernias in cats happen when the umbilical ring does not close up all the way after birth. It generally appears as a soft swelling under the skin near the belly button. It is often more visible when the cat stands up, meows, or cries. They're not painful, and they typically close up on their own by the time the kitten is three or four months old.

Diaphragmatic Hernia

The diaphragm is a muscular wall that separates the heart and lungs from the contents of the abdomen, such as the stomach, liver, and intestines. When this muscle contracts, it helps fill the lungs with air. Diaphragmatic hernias can be caused by a serious accident like getting hit by a car. They can also occur due to a congenital condition. Signs of a diaphragmatic hernia include trouble breathing, a rapid and shallow breathing pattern, and holding the head and neck in an extended position.

Hiatal Hernia

A hiatal hernia happens when the stomach or other organs push past an opening near the diaphragm. This rare type of hernia is typically the result of a congenital condition and usually appears before a kitten is a year old. However, it may also be caused by a traumatic injury. In some cases, the symptoms of the hernia may come and go, which is referred to as a sliding hernia.

Symptoms of Hernias in Cats

One of the most obvious signs of a hernia is a small and squishy protrusion, which may occur around your cat's belly button or abdominal area, depending on the type of hernia. Inguinal hernias can also cause swelling in the groin. Other signs of cat hernias include:

It's important to visit the veterinarian if you think your cat has a hernia. Cats with hernias typically have a good prognosis, but sometimes the intestines can get trapped in the muscle wall and lose blood flow. This can be a life-threatening situation since the intestinal tissue will start to die and release toxins that are harmful to your cat.

At your veterinary clinic, the doctor will ask you about your cat's symptoms, review your cat's medical history, and do a nose to tail physical exam. This will include checking for any swelling or protrusions that might indicate a hernia.

Your veterinarian may also perform bloodwork to assess your cat's overall health and rule out any underlying illnesses. In addition, X-rays or an ultrasound may be recommended to confirm the diagnosis of a hernia and help determine the best course of treatment.

Treatment of Hernias in Cats

In some cases, your veterinarian may be able to push the tissue and organs that pushed through the weakened muscle back into place. However, your cat may still require surgery to strengthen the area and prevent the hernia from recurring.

During hernia surgery, your veterinarian will repair the muscle and cover it with mesh to help keep organs or tissues from pushing through it again in the future. They can also repair cat hernias after a spay or neuter is performed. This way, the cat only needs to undergo anesthesia and post-op recovery once rather than twice.

Surgical repair of diaphragmatic hernias is usually an emergency situation. In addition, they may be complicated by other injuries if the hernia is due to an accident, such as getting hit by a car.

Post-op Care

Your veterinarian will give you instructions on how to care for your cat after surgery. This can include:

You'll also need to take your cat back to the clinic for one or more follow up visits. During these visits, they'll make sure your cat is recovering without any complications and remove any staples or stitches.

Risk of Aspirational Pneumonia

Cats who had surgery for a hiatal hernia can be prone to aspirational pneumonia. This occurs when they inhale something foreign into their lungs, which irritates the sensitive lining. Symptoms can include deep coughing, difficulty breathing, rapid heartbeat, blowing out of the lips, and bluish lips. If you notice these signs or any other problems after surgery, contact your veterinarian right away.
