Cats get seasonal allergies to pollen and grass, and some have year-round allergies to fleas and dust mites. Sandy Willis, a veterinary internist who advises the American Veterinary Medical Association, says that when cats interact with an allergen, their body sends immunoglobulin E antibodies to link with it, triggering the release of histamine and other chemicals that cause itchy eyes, runny noses, sneezing, hives and rashes.
As part of the cosmetic industry's attempt to shift away from animal testing for makeup, L'Oreal and the Hurel Corporation have designed a new chip that simulates the behavior of skin cells, eliminating the need to test the allergic response of lab animals to cosmetics.

The incidence of asthma and allergies are on the rise. In the United States alone, asthma rates have doubled since the 1980s. And, according to a recent article by the BBC, doctors once estimated 15 percent of the population had some type of allergy, but now believe the figure is closer to 40. More patients are also suffering from multiple allergies than ever before. The reason for this trend has been widely disputed, but a new study points the finger at a surprising culprit: lice.
