I really hope you can find some way to keep Martha As an asthma sufferer myself virtually al my life, 50+ years, I too had a severe reaction to cats when I was very young so I know what it's like. I still have a reaction now and again but only in the summer. Maybe antihistamines can help, worth a try. Do you have inhalers?
As you may know it's not actually the cat that you are allergic too but the dander, saliva and urine and things that they can bring in with them, mould spores and the like. I read somewhere that there are some wipes you can get to help keep the dander down. I will see if I can find it again.
I really don't know what else to suggest and that you can overcome this and keep Martha
