How to Wash a Cat at Home, and How to Wash Their Bedding

By the SHENHE ZHONGKE R&D and compliance teamReviewed by our compliance team

Two separate questions usually get searched as one: how do you bathe a cat, and how do you clean the things the cat sleeps on. They have almost nothing in common in practice, and the second one solves a smell that the first one cannot.

This page covers both, including the case where the answer to the first is that you should not bathe the cat at all.

When a cat actually needs a bath

A healthy adult cat that grooms itself does not need bathing. This is not a preference; a cat's own grooming removes loose hair and distributes the oils that keep the coat conditioned, and washing that off leaves the coat dull and the skin more prone to irritation. Cats that are bathed on a schedule tend to need it more.

A bath is warranted in a short list of situations:

After a flea or topical treatment, because the product has to reach the skin rather than sit on the coat. After an episode that soiled the coat, particularly diarrhoea, where the coat is genuinely contaminated. When a long-haired or show cat cannot groom an area itself — mats behind the ears and in the armpits are the places a cat physically cannot reach.

Everything else on the list of reasons to bathe a cat is usually a grooming problem or a dirt problem, and both are better solved without water.

Doing it without a fight

The resistance is about the process, not the product. Four things change the outcome more than any shampoo:

Brush first. A matted coat cannot be washed — the mats hold water against the skin and dry slowly, which causes the exact skin problems the bath was meant to prevent. Remove mats before water goes anywhere near the cat. Use lukewarm water and a non-slip surface. A cat that loses its footing panics, and a cat in a laundry sink is not gripping. Keep it short. A five-minute wash is enough. A long one is what turns a bath into a memory. Dry properly, all the way through. This is the step most often skipped and it is the step that matters most.

The drying step is the one that actually prevents the smell

A cat that smells a day or two after a bath is almost always damp rather than dirty. Moisture trapped at the skin creates conditions for bacterial growth, and the result is an unpleasant smell that no product applied to the coat will fix, because the problem is under the coat rather than in it.

Towel-drying lifts the surface water and does little else. The coat underneath stays wet. Drying has to reach the skin: a hairdryer on a low setting, kept moving, until the coat feels dry all the way through rather than just to the hand on top. For a long-haired cat this takes longer than most people expect.

The product, and the one mistake to avoid

Use a product formulated for cats and dogs — a mild coconut-derived surfactant base, and nothing heavily fragranced. The mistake is using a dog shampoo on a cat. Dog products are frequently more heavily scented, and cats are the animals most likely to react to strong fragrance and to essential oils such as tea tree and citrus.

For a cat that cannot tolerate a bath, a no-rinse foam removes most of the objection: no tub, no rinsing, minimal drying. It is a spot clean rather than a full bath, so it suits a dirty patch, a matted area a cat cannot reach, or a cat too stressed for the full procedure.

Now the other half: the bedding

A room where the cat is clean can still smell of cat, and the reason is usually the blanket, the towel or the cat bed rather than the animal. Bedding holds the residue that a coat sheds over time, and ordinary laundry detergent is built for fabric and general soil rather than for organic residue.

A detergent formulated with biological enzymes does a different job. Enzymes break down the specific organic compounds that produce the smell, rather than merely suspending them in water and leaving them in the fabric. This is the same principle as the litter deodorizer, applied to textiles instead of to litter.

The practical habit is to wash cat bedding hot and to wash it more often than feels necessary. A blanket that is washed monthly can hold a build-up that a single wash does not clear, because the residue has had a month to accumulate.

What to keep on hand

Three things cover most of it, and none of them needs to be used on a schedule:

A mild wash for the rare real bath. A no-rinse foam for spot cleaning and for cats that will not tolerate a bath. And a detergent formulated for pet bedding and clothing for the things the cat sleeps on, which is the item most households do not buy and then notice the absence of.

Minimum order, price and production time for any of these are confirmed against a specific enquiry once the destination and quantity are known.

Frequently asked

How often should I bathe a cat?
Rarely. A healthy adult cat that groomes itself does not need bathing — repeated washing strips the coat of its natural oils and can make the coat dull and the skin prone to irritation. A bath is warranted after a flea treatment, after a diarrhoea episode that soiled the coat, or when a long-haired or show cat cannot groom a matted area itself.
Should I use dog shampoo on a cat?
No. Dog shampoos are frequently more heavily scented, and cats are the animals most likely to react to strong fragrance and to essential oils such as tea tree and citrus. Use a product formulated for both, or specifically for cats.
Why does my cat smell after a bath?
Most often because the coat is not fully dry. A damp coat traps moisture at the skin, which encourages a bacterial smell within a day or two. Drying the coat properly — not just towel-drying the surface — prevents this as much as any product does.
Can I use a no-rinse foam on a cat?
Yes, and it is one of the better options, because the objection to bathing a cat is usually the tub and the drying rather than the product. Avoid the eyes and ears, and never use it on broken skin.
Why do I need a separate detergent for cat bedding?
Because ordinary laundry detergent is built for fabric and general soil, not for organic residue. A detergent with biological enzymes breaks down the urine and faecal residue that settles into bedding and towels, which is what produces a persistent smell in a room where the cat itself is clean.
