I have asthma, and know that it's just NO FUN when you can't breathe. Prednisone is a help, but tthe funny thing is that with me, it makes me *think* I'm hungry - starving - all the time! I'm always glad when I'm back off it. Wonder if it'll do that for Josie! Yup, dust and dust mites are a common asthma trigger, and get me every time. And a cat is closer to the floor, too. Josie has my sympathy ... but I also know that it is pretty well understood, and treatable, so it's not the end of the world!
