No, short haired tabbies are not hypoallergenic. However, they may be less likely to trigger allergies in some people than other cats with longer hair. Allergies are caused by a protein called Fel d 1, which is found in cat saliva and skin. This protein can be transferred to a cat's fur when they groom themselves. Short haired cats have less surface area for this protein to cling to, which may make them slightly more tolerable for people with allergies. If you're allergic to cats but still want to adopt one, consider choosing a short haired variety.
