It may sound like a stupid question. Cats spend up to 50 percent of their waking time grooming themselves, so would they ever really need a bath?
Do Cats Need Baths?
The good news is this: under most circumstances, most shorthaired cats do not require regular baths. Because of their advanced grooming skills, domestic cats (at least, the shorthaired variety) don't generally require baths with any regularity.
Additionally, certain types of cats may need regular or semi-regular baths. For example, longhaired cats may not be able to groom themselves as much as is needed to keep their coats clean. These cats may require more frequent bathing than their shorthaired counterparts. Certain health issues can also contribute to a greasier or matted coat, which can mean more regular bathing is needed.
Be aware that excessive bathing is not only stressful for cats, it can also cause their skin to become dry, flaky and itchy. So don't give your cat a bath unless you're sure it's necessary.
If you're not sure how often your cat needs to be bathed, it's always a good idea to check with your veterinarian. They'll help you determine your cat's bathing needs based on coat type, health issues, and any other considerations you may have.
