Advices for cat/dog allergy

Dogs and cats cause allergy through particular proteins (allergens) secreted by their sebaceous glands and present above all on the animal’s hair and skin, but also in its saliva and urine. They are very light allergens, which remain suspended in the air for a very long time and they accumulate on fibres and fabrics (carpets, curtains, couches and armchairs, mattresses, pillows, clothes, etc.). Their concentration is highest in the houses where the dog and cat live, but significant quantities may also be found in places not frequented by the animals: as the allergens adhere to the fabrics, they can be transferred anywhere. That’s why even people who do not own a cat can still become sensitive to cat allergens.
Dog and cat allergies have increased a lot in recent years and nearly always affect people who are already allergic to mites; this is because mite sensitisation favours the onset of other allergies.
