Although attributing "bad luck" to coming across a black cat is only the result of superstition, a study by scientists from Long Island College Hospital in New York (USA) recently revealed that these felines can adversely affect allergy sufferers .
According to a study published in the Annals of Allergy, Asthma and Immunology , researchers observed that dark-haired cats caused more sneezing and respiratory problems in allergy patients than light-colored cats. According to the authors, it is because they produce more of a substance in your skin, saliva and sebaceous glands, the protein fel d1, that causes allergy symptoms.
