Hi Scarlett,
I have a brother who has two cats, he has copd & short term memory loss. It drives me to distraction he has cats because of his copd & the cat dander I go and clean, when he lets me. He cleans, but not in detail. I have asthma, I'll take an antihistamine but still feel itchy & chesty when I get home. Cats get in to every single room & on every surface. I have to concede that his cats are actually good for him 'emotionally' & make him happy, but not physically. His cats try to approach me but I consistently drive them away. I'm very aware of 'hair' ... can't stand it personally.
