I am allergic to my roomate! I have a huge red welt on my leg where he rubbed up against it. I’ve had cats all my life but suddenly if they are on my bed like he is here, I am getting red itchy red welts all over my legs and arms. As much as I hate it I have had to keep the cats (there are two) out of my room and off my bed, except tonight when a moth got in then they worked hard to get rid of it. They are so cute and so loveable, I love playing with them, they are so affectionate. They need a lot of attention and no one seems to be around to give them TLC and I like them a lot but I am scratching all over and it is a bummer! It is wierd that this allergy started now at age 44??? has anyone ever experienced anything like this?
