Some animals can produce allergic reactions in people - in particular cats. Cats glandular secretion is embedded in their fur when grooming and subsequently it is released into the air. Insufficient air circulation can cause breathing and touch allergic reactions. The World Health Organization refers to bee sting allergy as a common global problem which makes sense considering there are 20,000 different bee species worldwide. Our Bee and Insect Sting emergency warning card is available in many languages.
