Do Cats Need Baths? Vets Settle the Debate

Cats are famously meticulous groomers—which you already know if you've ever admired one methodically licking every inch of their fur, charmingly using a paw to get to the areas they can't reach on their faces. (Too cute!) With all that fastidiousness, you’ve probably wondered whether they ever need a proper, human-administered bath.

The short answer: usually not, vets say.

Like many pet-parenting questions though (for example: should cats sleep in bed?), the answer isn’t entirely black and white. While healthy cats are generally well-equipped to keep themselves clean, veterinarians say there are a handful of situations where bathing them isn't just helpful—it’s important.

For most healthy cats, regular baths simply aren’t necessary.

“Healthy cats normally do not need baths,” says Amanda Nascimento, D.V.M., veterinarian at NHV Natural Pet. “They groom themselves very effectively, and bathing can remove the natural oils that protect their skin and coat.”

Those natural oils help keep skin healthy and fur in good condition, so washing them away more frequently than necessary can leave cats with dry, irritated skin. On top of that, baths are stressful for many felines, making the experience unpleasant for both the pet and the pet parent. (You might have the scars to prove it after a run-in with some sharp claws on a displeased feline.)

Instead, routine brushing is usually all that’s needed, particularly for cats that shed heavily or have longer coats. Brushing helps remove loose fur, minimizes mats, and supports the grooming your cat is already doing on their own.

Another reason to think twice before reaching for the shampoo: A bath temporarily changes your cat’s scent.

“Cats rely heavily on their scent to recognize one another,” Nascimento explains. “After a bath, other cats in the household may not recognize them, which can sometimes lead to hissing, avoidance, or mild territorial behavior until their normal scent returns.”

That doesn’t mean cats should never be bathed under any circumstances.

Veterinarians say bathing is appropriate when a cat gets into something they shouldn’t lick off, such as grease, paint, chemicals, or another potentially toxic substance. In those cases, a prompt bath can prevent your cat from ingesting something dangerous during grooming.

Baths may also be recommended if your veterinarian prescribes a medicated shampoo to treat a skin condition.

Some cats simply need a little extra help staying clean, too. Older cats, overweight cats, or those with arthritis or other medical conditions may have trouble grooming themselves effectively. Likewise, cats with diarrhea or lots of grime may occasionally need assistance getting clean.

Long-haired cats are another exception. While they don’t necessarily need frequent baths, they do require consistent coat maintenance.

“Even if they don’t need a bath, they do need regular—and I mean daily—brushing and combing to maintain their coats and prevent matting,” says Helle Brandrup, a veterinarian with Neurogan Health.

If you do find yourself bathing your cat, the goal is to make the experience as quick and low-stress as possible.

Nascimento recommends using lukewarm water and a shampoo specifically formulated for cats. Never substitute dog shampoo, she says, since some ingredients found in canine products may not be safe for feline skin.

Keep the bath brief, avoid getting water in your cat’s eyes or ears, and reward them afterward with treats or praise to help establish a more positive association with the experience.

For smaller messes, however, you may not need a full bath at all. Brandrup says grooming wipes or a damp cloth are often enough to clean dirty paws or small soiled areas, especially for cats that become extremely anxious around water.

If your healthy indoor cat has never had a bath, that’s probably a sign you’re both doing just fine.

Unlike dogs, cats evolved to be expert self-groomers, and for the vast majority, that’s more than enough to keep their coats clean and healthy. Unless your cat gets into something hazardous, develops a medical condition that requires medicated shampoo, or can no longer groom effectively on their own, veterinarians agree that it’s usually best to let them handle bath time themselves.
