Why is my asthmatic cat lethargic, not eating, and breathing hard?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 14 lbs

My FIV+ cat is 3 yrs/o, weighs about 14lbs. Despite being diagnosed with asthma and losing nearly all of his teeth, he's been a healthy and happy boy with a good appetite that we've had to limit due to his weight. The last two days I've noticed that he's been more lethargic than ever, has stopped eating and drinking his normal amount, and this morning seems to be having a harder time breathing--his nose is stuffy and he's breathing from his mouth. What can I do to help him?

Poor Potato! He needs to be examined by a vet right away if he is having a hard time breathing. He could have a problem with his asthma, infection, or fluid in/around his lungs. Your vet can take an x-ray to evaluate his lungs and then determine the best way to treat. He may just need an antibiotic, anti-inflammatory, bronchodilator, or other medications depending on the cause. Call your vet and have him examined as soon as possible.
