Cats may eat hair for several reasons. One common explanation is that they’re grooming you, much like they groom themselves or other cats. Your hair might carry your scent, and licking or nibbling it could be a way for your cat to bond with you. Another possibility is that your cat is attracted to the texture or movement of your hair, especially if it’s long or dangling. While occasional hair nibbling isn’t usually harmful, swallowing large amounts could lead to hairballs or digestive issues. If your cat seems obsessed with eating hair, it’s worth consulting a vet to rule out nutritional deficiencies or compulsive behaviors.
