I mentioned last week that Cupcake had hernia surgery just before joining our family, and I got a couple questions about it afterward. So today, we’re going to talk about cat hernias.
What is a Hernia?
A hernia is a condition that affects both humans and other species of animals. It means that there is a weak spot in the abdominal muscles or in the diaphragm, and that tissue or organ is bulging through the weak spot.
Hernias very from small and nearly unnoticeable to larger, depending on how big the area is of weak muscle. In rare cases, hernias can become dangerous if the contents of the hernia are constricted where they pass through the hernia and can’t get blood flow. This is called a strangulated hernia.

Hernias have different names depending on where on the body they are found. For instance, umbilical hernias are at the site of the belly button, while diaphragmatic hernias are abnormal openings in the diaphragm.
Umbilical Hernias
Cupcake had an umbilical hernia, the most common hernia in cats. These can be hereditary, but can also be caused if the umbilical cord was pulled too hard or if the mother cat chews the umbilical cord too close to the infant kitten’s belly.
Since a cat’s belly button is actually a small opening where the umbilical blood vessels are attached before the kitten is born, it is a small opening that needs to close in every kitten after birth. This means that small umbilical hernias are not uncommon with kittens. Small hernias may close on their own while the kitten is growing for her first few months.
Umbilical Hernia Repair
Cupcake’s hernia was small enough that it wasn’t caught until after her spay surgery. But she was nearly three months old, and she was about to take an airplane flight and be adopted. Even though her hernia was small, we decided it was safest to have her hernia taken care of, so she was scheduled for hernia surgery. The surgery for a an umbilical hernia wasn’t more strenuous on her than her spay surgery, and she was able to travel the next day.
A week later, the most noticeable thing about her surgery site is that her tummy is shaved.
If you look closely, you can see some of the surgical glue left on her fur, and just above that, a pinker bulge where the absorbable stitches are holding together the layers of muscle so they can heal properly. Our vet examined her over the weekend and said she is healing well. We expect the bulge will probably become less noticeable and may even flatten out entirely once she finishes healing.
It certainly hasn’t slowed her down a bit! Kittens who go through hernia repair are just as bouncy and rambunctious as any other kittens. So if your vet tells you that your new kitten has an umbilical surgery, don’t panic. Cupcake says that getting all fixed up is a piece of cake.

As a teenager, my human had a kitten that had an umbilical hernia. The vet said it would heal on its own… and it did.
Thanks for the info! I am glad Cupcake is in good hands and just as rambunctious as any good kitten!
I am so happy for the outcome.
We’re glad to hear Cupcake breezed through that surgery and is okay now.
and normally they are caught early and just fixed at the time of spay (or neuter) surgery. poor baby showing off her bad haircut 🙂
We’re glad she’s doing well. And soon you can tickle her bellybutton! (Here, Izzy loves that.)
Good info!!! Cupcake is soooooooo cute!!

Very interesting. We’re glad everything went well for Cupcake. Purrs
that photo of her ‘standing up’ and showing her belly is freakin adorable.
I’m so glad she is doing so well
Cupcake, I just want to grab you! I had never heard of hernias in kittens and am so happy she breezed through the procedure!
We’re so glad Cupcake is healing nicely. We never knew a cat could have an umbillical hernia.
We are all sure glad that sweet Cupcake is doing okay now!
Whoa! I didn’t know we could get hernias too. Pop had to have surgery for one he got from picking up Nicky’s case to rush him to the ER vet the night he died. Great info and glad Cupcake is sweet as ever.
I am glad everything went well. She is a cutie.
We are glad Cupcake is doing well. TBT tried ta find our belleh buttons, but we wouldny let him…
I’ve heard of hernias … but not umbilical hernias. Cupcake’s was and is in the very best hands 🙂
So happy to hear Cupcake is healing nicely from her surgery.
Great graphic and cute kitten belly. It’s always a good idea to keep your innerds where they’re supposed to be!
My kitten had this surgery 4 days ago and it is near impossible to keep him from running around.
I really hope he has not ripped open his inside sutures
