Cat dander is one of the most common allergy triggers worldwide. A new therapeutic approach is now heralding an imminent breakthrough in treatment. Professor Randolf Brehler from the University Skin Clinic in Münster is involved in one of the worldwide studies on this – and explains the new approach.

Professor Brehler, just to be clear: a cat allergy is not a cat hair allergy, right? In common parlance, the term cat dander allergy has prevailed because the cat allergen is in the saliva of the cat and she spreads it on her fur when she grooms herself. From there it gets into the air and settles on textiles and other surfaces. Strictly speaking, the hair of a freshly washed cat would not cause any problems for a cat allergy sufferer.
