Hello Welcome to health care magic Thanks for your query. I think in your case first we have to evaluate you properly before diagnosing you as an asthmatic or you had developed allergy towards your cats. First you should take a chest X-ray and consult with a pulmonologist to rule out other pulmonary conditions. A simple peak flow meter testing for peak expiratory flow rate will give an idea about you problems. Further your can stay away from your cats and see if you get better. To confirm your allergic condition you can do specific IgE tests or radioallergosorbent tests (RASTs). Treatment for your pulmonory problem might involve administration of antibiotic therapy, anti-histaminic therapy (such as citrizine), and salbutamol can be helpful for the relief of bronchospasm (Chest Tightness). Consult pulmonologist and take further suggestions Wish you a good health. Dr Kidev.S
