Cat allergy is the most common pet allergy, causing itchy eyes, rashes and sneezing. It also triggers or exacerbates asthma in up to 40 per cent of those with the condition.
The allergy is mainly caused by a protein called Fel D1,it is made by the salivary and hair root glands, and when cats wash themselves, they transfer it to their fur and skin. Microscopic flakes of cat skin, dander, are breathed in from the air, walls or clothing and cause problems when they are wrongly identified as being a threat by the ‘watch-man’ cells if the immune system.
These dendritic cells then send signals to the other immune cells to mobilise, creating the symptoms of an allergic reaction.
