Have Cat Questions? Ask a Cat Vet Online.
I am sorry to hear you are worried about Lacy. My name is Rebecca. I am a veterinarian and will do my best to help.
Most cats with pneumonia have a fever (rectal temperature over 103), coughing, sometimes open mouth breathing and pale gum color. An Xray will confirm if there is fluid in the lungs which is usually seen with pneumonia.
Coughing can also be a sign of asthma, allergies, or an upper respiratory infection that is not in the lungs as opposed to pneumonia which is an infection in the lungs. Another cause of coughing in an older cat can be cancer. In a cat as old as Lacy, I would get a chest Xray as soon as she can see her veterinarian.
Let me know what other questions I can answer.
A meow without making a sound can be from an inflamed throat, but probably not pneumonia. She may have lost her meow from an infection, a sore throat, swollen glands, or because she is having breathing difficulty. I would need to examine her, feel her lymph nodes, take her temperature, listen with a stethoscope to tell you what her problem might be.
I am sorry, I can't make phone calls for the website. Sorry I stepped away from my computer for a few minutes. If you want me to opt out, and let another expert help you, let me know.
