My kitten is panting fast. Can a congenital heart defect be cured?

To me, this doesn't sound like allergies. I'm concerned there could be something wrong with Fuji's heart, but don't freak out at that because I can't say for certain without seeing him in person. I'd take him back into the vet for this behavior. Best of luck.

Your kitten will need to have an exam by your veterinarian. She could be suffering from a congenital malformation of the blood vessels near the heart or have a hole in the septum of the heart. This would often not show when the kitten is resting, but when it exercises, runs and plays there is not enough oxygen being pumped to the lungs and muscles because oxygenated and used up blood mixes. Problems often do not occur until 3-4 months of age. Please make an appointment with your vet for an exam.

Respiratory issues in kittens can be quite serious and I would definitely have a vet see your kitten. Smoking around your kitten can also be very damaging and it would be ideal if you smoked outside. Many animals develop lung cancer when they have owners who smoke and this unfortunately isn't widely known. This issue probably has more to do with an underlying condition and I would have your kitten seen ASAP. I hope Fuji feels better soon!

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. When cats pant or breathe with their mouths open, this is abnormal and concerning. Given the information you provided about the Merlin's heart murmur, I am worries that he could have significant enough heart disease to cause heart failure, which leads to the build up of fluid in the lungs. This makes it very difficult for cats to breathe, especially after exertion, and can be life-threatening. Alternatively, cats can pant when they are severely overheated, which is also very dangerous. I would recommend keeping Merlin quiet (no running or playing) until he can be seen by a veterinarian. He/she will want to do a full physical exam and take x-rays of Merlin's chest to look for heart enlargement and/or fluid in the lungs. There is a blood test available called an NT-proBNP that can detect heart failure in cats as well. I hope this information is helpful!

Thanks for using Petco Pet Education Center, formerly Petcoach! While panting and open mouth breathing can be due to nervousness to some extent, this most likely signals a respiratory condition such as asthma, heart disease, among many other possibilities. I highly recommend you consider taking Fluffy to your veterinarian for further assessment and treatment. They will likely recommend starting with an exam and chest radiographs. Hoping for the best! Good luck and have a great day!

Without seeing Mao in person, I can't do a definitive evaluation on him or say his life expectancy, etc. I would need to examine him in order to answer your questions. I recommend taking him into a vet. The vet can examine him and answer those questions. Best of luck.

I would be very concerned for cardiac disease or infectious disease (pneumonia) based on those radiographs. With a temperature of 35 C (95 F) that is absolutely an emergency situation. You can see panting with cardiac disease when pulmonary edema begins to develop, which is when fluid is present within the lung tissue and does not allow for adequate gas exchange to occur. I recognize that this was posted 3 days ago, but if Sasi has not been re-evaluated by her veterinarian she needs to be ASAP to determine a treatment plan and if further diagnostics are indicated (echocardiogram, airway wash, etc.).
