I too am plagued with this foul disease.
Clearly, you need to kill the cat.
This would be my first line of defense, but if this is not an option, take 25-50 mg of diphenhydramine(found in benadryl) or 10-15 mg of loratadine, I'm not sure what the generic name for this is. Both however have prooved successful in the past at subsiding my reaction. Diphenhydramine will make you sleepy, loratadine is a non-drowsy antihistamine, just something to keep in mind.
Cat is gone. I have all my clothes and stuff in another room and I am slowly washing it all to get rid of any cat hair if it got on anything. It is just the breathing part. Will it go away or should I drive to a hospital lol
Don't waste a hospital trip, trust me, once you're away from the cat it
will go away. When I stay with my brother(he has a cat) for more than a day I start to have trouble breathing, I've always assumed it was a combination of the cat allergies and all the smoking that I do. When it gets so bad that I can't even sleep because I have to focus on breathing, I take a nice long,
hot shower. I can't say entirely why, but it always helps.
I've learned from these experiences though and now when I go over I stop smoking as soon as I have trouble breathing and it usually doesn't get too bad.
