Just about everyone I know claims to be allergic to cats. I only know of one person who claims to be allergic dogs. Are cat allergies more common than dog allergies?

I did a guick Google search and found that yes, cat allergies ARE more common than dog. I didn't know that!

What Causes Pet Allergies?

While unattractive pet hair may cover the furniture and clothing of some pet owners, it isn't actually the hair that causes an allergic reaction. Instead, it's the tiny skin flakes, or dander, clinging to these hairs that cause the reaction. In addition to dander, things like pollen, mold, and dust can also collect in pet hair, becoming airborne or stuck to furniture as a pet moves around. Still other pet products can be allergens, such as the proteins in saliva and urine. And while cats don't generally lick those who pet them, they do clean themselves with their tongue, spreading saliva to nearly every inch of their bodies.

What Makes Cat Allergies More Common?

It's difficult to say exactly what causes cat allergies to be more common than those of dogs. It could be a combination of things, including the possibility that the allergens in cat dander and saliva are simply more potent (fewer particles needed to produce a reaction), or because cats aren't very often bathed. Also, male cats produce the allergen in dander in response to hormones. So if a male cat remains non-neutered, it is capable of producing larger amounts of allergen. Cat dander is also incredibly small and sticky, allowing it to stick to clothing and be efficiently transferred. So even if you don't have cats, you could very well have cat dander floating around the air in your home.

I am allergic to dogs, not cats but I too know many more people allergic to cats. I can be around a cat and have no problems at all but you throw a dog in the room and my throat itches and swells and my eyes start running.

Both cat and dog allergen are microscopic. You cannot see it with a naked eye. Cat allergen is many times smaller and lighter than dog allergen, so it remains in the air longer than dog allergen and, thus, is more susceptible to reach the lungs and cause symptoms.
