What is Chest Bone Deformity?

Chest bone deformity in cats typically refers to a common deformity known as “funnel chest,” which is known by the medical term "pectus excavatum". Pectus excavatum is a condition in which the chest bone (sternum) and the ribs to which it is connected grow abnormally. The result is a chest that has a sunken or concave look; ideally it should look slightly convex.

Symptoms of Chest Bone Deformity in Cats

The definitive manifestation of pectus excavatum is the aforementioned sunken appearance of the chest bone. The deformity compresses the lungs and the heart, thus hampering their ability to function normally. As a result, the affected cat has difficulty breathing, and when it does, there’s an increased depth to the breathing. Also, it can be quite a struggle for the cat to move around, let alone do routine exercise. 

Other symptoms of chest bone deformity include:

  • Coughing
  • Failure to gain weight
  • Fatigue
  • Poor appetite
  • Regular occurrence of lung infections
  • Vomiting

Causes of Chest Bone Deformity in Cats

Currently, there is no known cause of chest bone deformity in cats. Although some researchers believe that some cat breeds are genetically predisposed to develop pectus excavatum, no cat breed is spared from the condition. Indeed, chest bone deformity can occur in cats that are less likely than others to develop it. However, researchers theorize that the deformity occurs when the costal cartilages—which constitute connective tissue that join the ribs to the chest bone—grow in an irregular fashion. This causes the chest bone to move inward. Also, chest bone deformity is linked to other conditions, such as Marfan syndrome, which is a connective tissue disorder.

Diagnosis of Chest Bone Deformity in Cats

To make a diagnosis of pectus excavatum, the veterinarian to which you take your cat needs a full and complete history of its health. Informing him or her of the cat’s breed, parentage, genetic background, and onset of signs and symptoms would be extremely helpful. The veterinarian will get x-rays of the thorax to check for any abnormalities. Usually, veterinarians stick with just x-rays. In some instances, however, he or she might be required to go further to determine a diagnosis. This includes using echocardiography to take pictures of the heart to see if it has shifted from its normal position, or whether it has any functional defects. Some questionable findings, such as a heart murmur, may warrant ultrasound. Also, there may be reason to conduct a urinalysis or a series of blood tests.

Treatment of Chest Bone Deformity in Cats

Once a diagnosis of pectus excavatum has been made, the veterinarian determines the best course of treatment for the condition. In some cases, the condition is mild enough to skip treatment altogether. Depending on the mildness of the deformity, the veterinarian will guide you in compressing the chest in a way that brings the chest bone and costal cartilages to the normal convex shape, or he or she might introduce a splint to do so. However, if the cat has symptoms or the chest is compromised based on the captured radiographs, the deformity is severe enough to deserve treatment. Currently, surgery is the only mode of treatment for chest bone deformity in cats. This usually involves one of the following:

  • Sewing a fiberglass cast around the chest bone, which is pulled away from the lungs and heart
  • Removing the affected portion of the bone and replacing it with a graft

The method of treatment that the veterinarian chooses depends on how bad the condition is and how old the cat is. During surgery, there’s always the risk of the cat succumbing to air leaking in the chest (pneumothorax) or bleeding into it due to needle penetration. The first few weeks after treatment is crucial, since there’s a strong chance of complications occurring. Sores tend to develop on the underside of the cast, so make sure you rub them when it’s time to remove them as advised by the veterinarian. 

Recovery of Chest Bone Deformity in Cats

Watch out for breathing difficulties, especially during the first two days after surgery. If you detect any issues with the cat’s behavior, breathing, or chest movement, call your veterinarian immediately. The cat is prescribed antibiotics for two weeks, in addition to a short course of painkillers. You should give it manual lateral chest compressions to help decrease the sunken appearance. If the cat gets the fiberglass cast treatment, the cast is kept in place for the next six weeks. Ensure that the cat limits exercise or moving around when the cast is on, especially considering that it may feel sore. It should be kept away from other animals, as well as active children; the best way to ensure this might be to keep it in a cage. Also, change the cat’s bandage material every two weeks.

My 7 week old kitten seems to have a narrow, pointed rib cage, rather the opposite to pectus excavatum. Does not seem to affect her at the moment, plays happily with siblings, but I can't find anything like this on the net.

Without seeing your kitten, unfortunately, I can't comment on what might be going on. If it is concerning you, it would be best to have her examined by a veterinarian, as they will be able to determine whether she has a problem or not. She is at an age where she needs preventive vaccines and deworming, so you should be able to combine those two goals with your veterinary visit.

7 yr old male cat chest depressed after exposure to solid gel room air freshener some months ago. Vet given an inhaler. After administrating this cat yawns a lot for several days. Walks and runs normally but has shortness of breath now and then. My question how can his chest come back out from this concave position and is using the inhaler not helpful as his lungs expand slightly with use not his chest.

Thank you for your email. I'm not sure from the details you have given what actually happened to Snuggles, or what condition he is suffering from with his chest. Since I can't examine him, and don't know the details of his situation, I can't comment on how his chest might heal - since you have had him seen by your veterinarian, and they know more about his health status, that would be a great question to ask them, and they will be able to give you a better idea as to what his prognosis is, and how to help him better if he isn't responding to therapy.

I have a Bengal kitten 7 months old. he just was declawed and neutered and the vet doctor told me they found Chest Bone deformity in him. He is not growing or gaining weight. After the declawing and neutering surgery he can't return to normal. sleep all the time and looks very depress, losing weight, even he is continue eating. I want to know how long he can survey without surgery. and what the other option beside the surgery you described in your post? How much a surgery can cost?

The answer to your question is that it depends; it depends on the severity of the deformity, subsequent health issues from the deformity and Caruso’s general health. As for cost of surgery; this will vary depending on (again) the severity of the deformity, your location (country, city etc…) and your Veterinarian (general or specialist). You should speak with other Veterinarian’s in your area and if you have an x-ray forward it on to them to give them a better idea so they can give you an accurate ballpark figure.
