What causes asthma in cats?
While there are a number of factors that contribute to asthma in cats, it is thought to develop as a result of allergic bronchitis.

Common factors that can contribute to the severity of an asthma attack include: • Allergens, including pollens, molds, dust from cat litter, cigarette smoke, perfume and certain foods • Pre-existing heart conditions or illnesses • Parasites • Extreme stress • Obesity Asthma-like symptoms in cats can also be associated with other disease, including heartworm, respiratory parasites, tumors, heart failure and pneumonia.
