Cats can be allergic to human dander. I think this is something which we should recognise. The problem is there is little knowledge about the actual allergen in human dander which causes an allergic reaction in a human. There is more on dogs being allergic to humans than for cats which is pretty typical because dogs are always much better represented in medical research than cats.
I'm looking at a study right now (link - don't bother clicking on it as there is nothing there 😉) about perennial indoor allergens among them house dust mites and moulds. Human dander is an important constituent of house dust and house dust is a major cause of allergic reactions in dogs and I would suggest also in cats from time to time. We don't know how often human dander in house dust causes an allergic reaction in cats.
This sort of allergic reaction would fall under the category of an environmental allergen. That's because the human dander is in the air inside the home and lying around on the floor and furnishings.
In addition to environmental allergens, there are food allergens and flea allergens. Flea allergy dermatitis can occur in cats.
The problem with cats being allergic to humans is that we don't know much about it! And when cats are allergic to humans, the human caregiver might not know about it either! That's because the symptoms or signs of the allergic reaction might be slight just as they often are for humans when they are allergic to cats.
Normally when a dog or cat is allergic to humans the reaction will be atopic dermatitis commonly known as eczema. Eczema in cats and dogs can be brought about by human dander. For the sake of clarity, human dander is dead skin cells and bits of hair which have flown off the human or humans and end up in the environment including on furnishings.
Apparently, of the one in five dogs (20%) suffering with symptoms of an allergy, half of them will be allergic to human dander.
Atopic dermatitis is not uncommon cats but little is known about how frequently it is caused by human dander.
Sometimes cats can be allergic to several allergens at the same time one of which might be human dander.
The treatment of allergies in cats is complicated. It's going to require specialist analysis by a qualified veterinarian and/or scientist. Sometimes a veterinarian will prescribe antihistamines but I don't want to get into treatments because I'm not a qualified veterinarian.
The purpose of this post is to highlight the possibility that your cat might be allergic to you!
