An estimated ten percent of the US population is allergic to animals. Ten percent of all US households have a pet dog/cat. The AAFA has observed that 15% to 30% of people suffer from dog/cat allergies, the latter allergies being twice the former. The fluids and dander from old skin tissues of pets (and not pet hair) cause pet allergies. These manifest as runny nose/eyes, sneezing, rashes, and other discomforts. Pet dander can also collect dust and pollen. Additionally, rodent or rabbit hair and faeces breed mold, fungi, and bacteria. Pets can also emit unpleasant odors in homes.
