My kitten is sneezing and mouth breathing. Is it allergies or a cold?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 2 lbs

My kitten has been sneezing (opening his mouth and blowing air out of his nose) every couple of minutes for the past day. He is breathing with his mouth open even when he sleeps. He still eats like normal and for the most part acts the same. Should I take him to the vet or is this a cold? Maybe allergies?

Yes, I would definitely take Smokey into the vet, as it's not normal for a kitten to breath through their mouth. It sounds like she is quite congested, and I can give you a home remedy to try to help that. Please know that it should not replace a visit to the vet, as she may benefit from medications to help with her symptoms. I would take her into the vet in the morning. Tonight, you can try using a humidifier or bringing her into the bathroom with the door closed while you take a hot shower - the steam and humidity help to break up congestion and temporarily relieve symptoms associated with respiratory infections.

    I am very sorry that Chucky is so unwell. I am sure this is very upsetting for you both. There are a range of possible causes for these clinical signs including a lung infection, respiratory virus, a heart condition or even a worm infestation. Unfortunately the clinical sign of breathing with mouth open means that Chucky is having respiratory distress and needs to be seen by a veterinarian immediately. He could have a life threatening condition. The veterinarian will be able to stabilise him by providing oxygen and close monitoring while they diagnosis the issue and develop a treatment plan. Please post any further questions you may have about Chucky. We at Petco Pet Education Center, formerly Petcoach are here to help you both.
