Excessive shedding in cats can be caused by a variety of factors, including diet, stress, allergies, and age. Diet deficiencies, such as lack of essential fatty acids, can cause a cat's coat to become dry and brittle, leading to excessive shedding. Stress can also cause cats to shed more than usual. Allergies can also lead to excessive shedding, as cats may scratch and lick themselves excessively due to an allergic reaction. Finally, age can also be a factor, as older cats tend to shed more than younger cats. Keywords: Excessive Shedding, Cats, Diet, Stress, Allergies, Age, Essential Fatty Acids, Dry Coat, Brittle Coat.
