i am allergic to cats!
You are just reacting to  to one or more allergens produced by cats.
oh yea? i never had issues with them until recently
The ones that your doctor will probably tell you about  are the glycoprotein Fel d 1, secreted by the cat's sebaceous glands and Fel d 4, which is expressed in saliva.
are there meds that i could take ?
Well, ER usually need to help and very bad cases  they cause the airway to become inflamed and close up,
that explains the issues im having!
So far so good, about 5 Five cat allergens have been noted by medical journal
thats good to know
Fel d 4 is the product of the cat major urinary protein gene
