Is it posslbe to have an indirect allergy to a cat? Could cholinergic urticaria be due to indirect cat allergy? I ‘m not allergic to my cat directly, but a friend told me that dandruff that I inevitably inhale from my cat is activated by heat alone.
My cat is indoors, so should seek a new home for my cat? Before my current cat, I had no cholinergic urticaria, even when I went for my cat day was sunny and there was no attack!
