For cats with medical needs, a wash every two weeks will help keep their coat healthy. Bathtime won’t hurt a cat, so if your cat loves water, and will easily allow you to bathe him, Proietto notes that you can give even a healthy cat a gentle scrub every month, if you so choose.
Giving your cat a bath every now and then can also be beneficial to owners with animal allergies. “Baths can help with dander and shedding, which can help to cut down on allergens,” Proietto says, “but most cats hate it and brushing once a day (with a Furminator) can help accomplish the same thing.”
While bathing can help both cats and their owners, excessive bathing can have unintended health consequences, such as dulling a cat’s coat, or causing dry, flaky, itchy skin.
