People often ask me if cats can get asthma. Unfortunately, the answer is a

can lead to wheezing, coughing, tiredness and difficulty breathing. Some cats
can also vomit or lose their appetite. A cat having an asthma attack may sit
with his head extended and breathe with an open mouth. Open mouth breathing is
abnormal in cats. If you see this, consider it a sign of emergency and contact
