My 7-month cat has fever, fast breathing, noisy lungs. Is it serious?

Pet's info: Cat | Persian | Male | unneutered | 7 months and 24 days old

Hello, my cat is 7 months old. I noticed he was breathing fast, lethargic etc we brought him to the emergency care. The vet noticed very high fever and some noise in his lungs. He has being eating and drinking water. We decided to keep him overnight there but I am so worried. He is an indoor cat and we are up to date with vaccines etc... I am so worried it may be something deadly or is it normal?

Hello, I'm sorry to hear this about Douglas. I think its a good idea that he is hospitalized with these signs of fever and noisy lungs. Persian breeds are brachycephalic, meaning they have a shortened nose and anatomically altered respiratory tract. This does make them more susceptible overall to respiratory infections like pneumonia. Some pneumonias can be viral induced (and then quickly get secondary bacterial infections which is why antibiotics are needed) and if that's the case, he should have at least some virus protection from his vaccines to reduce the disease severity compared to if he was unvaccinated. Many young cats will have respiratory infections and recover to live full, happy lives. Some of these cats will have chronic respiratory signs and disease over their lifetime afterwards, but this is often manageable and treatable. I hope this is helpful. I hope Douglas makes a speedy recovery in the hospital. Best wishes to you.
