Hernias in cats are less common than in dogs, but they do occur. The most common types are umbilical (in kittens), diaphragmatic (from trauma), and peritoneopericardial (congenital — organs push into the chest cavity). Some are harmless and can be monitored; others require surgery.
The average cost of cat hernia surgery is $800, with most owners paying between $150 and $2,000 depending on the hernia type.

Frequently Asked Questions
How much does cat hernia surgery cost?
Cat hernia surgery costs $150 to $2,000 depending on the type. Simple umbilical hernia repair costs $150–$500. Diaphragmatic hernia repair costs $1,000–$3,000. The average is $800. Most umbilical hernias in kittens can be repaired during spay/neuter for $150–$300 additional.
Will my kitten's umbilical hernia close on its own?
Small umbilical hernias (under 1cm) that can be pushed back in often close by 6 months of age. If still present at 6 months or if the hernia is large, surgical repair is recommended. This can be done at the same time as spay/neuter to save on anesthesia costs.
Does pet insurance cover cat hernia surgery?
Coverage depends on the type. Congenital hernias (present at birth) may be excluded as pre-existing. Acquired hernias (from trauma) are typically covered. Reimbursement is 70–90% after your deductible for covered procedures. Check your policy details.
What causes diaphragmatic hernia in cats?
Diaphragmatic hernias in cats are usually caused by trauma — car accidents, falls (especially from balconies in apartments), or dog attacks. Some are congenital (born with a hole in the diaphragm). Symptoms include difficulty breathing, rapid breathing, and lethargy. This requires surgery to repair.
Can a cat live with a hernia?
Small umbilical hernias can be monitored without surgery. Peritoneopericardial hernias (organs in the heart sac) can sometimes be left alone if the cat is asymptomatic. However, all other hernias should be repaired to prevent complications like organ strangulation or respiratory distress.
