Has anyone told you that asthma can kill you? I know you must love your cat, but is it worth possibly giving up your life? Cat allergin is very invasive and hard to get rid of. When you get rid of your cat, you are going to have to do extensive cleaning and even get rid of a lot of things that you cannot get the allergin out of. I suffered greatly from cat allergin and it took about a year to totally get rid of all the allergin. You will improve though, as it lessens in your enviroment. If I were your doctor, I would refuse you as a patient, if you refused to get rid of the cat. Instead of helping yourself, you want someone to give you medicine so you won't have to! Ask God to give you the strength to find your cat a new home. Air cleaners are great, but get rid of the cat first. Good luck.
