I've had my cat for only 4 months but in that time I've had problems with my asthma twice. I was using a purple inhaler everyday as told (sorry i don't know all the different names!) but I began to rely on my blue was too much. On a bad day I could use it up to about 10 times. The nurse couldn't understand why they wasn't working, and prescribed me a brown one, which worked for a few weeks but now I'm back to square one. I do have a cat but surly if I was allergic to him I'd be like this constantly?
