Hello. Thank you for asking at HCM. I went through your history and understand your question. Recurrent episodes of wheezing usually suggest asthma, be it allergic or non-allergic. There are so many types of asthma. As you have allergic reactions only related to cat exposure, it seems you are allergic to cat allergens (proteins from cat saliva, dander or urine which cause allergy). So avoiding contact with cat as well as avoiding visiting places with cat will be a way of preventing reactions. However, if it is not possible to avoid these, I would suggest you to consult an Allergist-Immunologist who may suggest allergy testing and immunotherapy which gradually trains immune-system to react differently to cat proteins. He may also suggest you spirometry with post-bronchodilatation reversibility test to see whether you have asthma and how your lungs function. Hope this will be helpful to you. Wish you best of the health. Regards.
