If lethargy, mucus, blood, diarrhea, vomiting or loss of appetite accompany a cat’s cough or are present on their own, contact your veterinarian as soon as possible.
If you notice that your cat has developed a cough, you should not ignore it. This symptom can mean that your cat has developed a more serious condition, such as heart disease, or a minor condition, such as a hairball. If you have the expertise, you can listen to your cat's lungs with a stethoscope. If you hear any irregular sounds, you should contact your veterinarian right away.
Locate your cat's lungs. On a cat, the lungs are located just before the bottom of the final rib.
Put the earpieces of the stethoscope in your ears. Be sure the room you're in is quiet so you can hear your cat's lungs accurately.
Place the head of the stethoscope on your cat's chest. The area toward the middle of your cat's chest is the best place to listen to the lungs.
Listen to several different areas besides the middle of the chest, including both sides and the neck area. If you hear any abnormal sound, including fluid, wheezing or a crackling sound, consult your veterinarian.
