Your cat’s bed looks fine. It doesn’t smell fine. Learning how to wash a cat bed the right way protects your cat from parasites, bacteria, and skin irritation — while keeping the bed intact. Here’s exactly what to do, and what most guides get wrong.
How Often Should You Wash a Cat Bed?
The answer depends on your cat’s routine, not the calendar.
- Indoor-only cats: every 2-3 weeks
- Cats with allergic owners: weekly
- Outdoor or semi-outdoor cats: weekly, sometimes twice
- Multi-cat households: every 1-2 weeks
Cats groom constantly, so their beds stay cleaner than you’d expect. But grooming doesn’t remove everything. Saliva, dander, and loose fur build up under the surface, even when the bed looks spotless.
Signs Your Cat’s Bed Needs Washing Now
Skip the schedule if you notice any of these:
- A sour or ammonia-like smell
- Visible fur clumps or shed skin
- Your cat suddenly avoiding the bed
- Damp or sticky patches
That last one matters. A cat avoiding its own bed is often the clearest signal something’s wrong with it — long before you can smell it yourself.

Why Washing a Cat Bed Matters More Than People Think
This isn’t just about smell. Untreated cat bedding can harbor flea eggs, dust mites, and bacteria that survive for weeks in soft fabric. Flea eggs, in particular, can remain dormant in bedding fibers until conditions are right to hatch — which is why a bed that “looks clean” can still be a problem.
Dander buildup is the other issue. It’s a leading trigger for pet allergies in humans, and unwashed bedding is one of the biggest reservoirs of it in a home. If anyone in your household has asthma or allergies, bed hygiene isn’t optional — it’s part of managing the condition.

Before You Wash: Prep the Bed Properly
Skipping prep is how beds end up damaged or washers end up clogged.
Remove loose fur first. Shake the bed outside or run a lint roller over it. This step alone prevents most washing-machine drain issues.
Spot-treat stains before the wash cycle, not during. Wet the area, apply a pet-safe stain remover, and let it sit 10 minutes.
Read the care label. Some beds are machine-washable only after removing internal padding or heating elements. Others are hand-wash only, full stop. Fifteen seconds of label-reading saves you a ruined bed.
Is It Safe to Wash a Cat Bed in the Washing Machine?
Usually, yes — if you follow the label and use the right settings.
Machine Washing: Step by Step
- Remove the cover from the padding, if separable
- Wash on a gentle or delicate cycle
- Use cold or lukewarm water, not hot
- Add a pet-safe detergent (more on this below)
- Skip fabric softener and dryer sheets entirely
When Not to Machine Wash
Beds with foam bolsters, non-removable heating elements, or memory foam cores often can’t handle a washer, even on delicate. Forcing them through anyway breaks down the internal structure and voids most warranties.
How to Hand Wash a Cat Bed
For bulky or delicate beds, the bathtub is your washing machine.
- Vacuum the bed to remove loose debris
- Fill the tub with warm water and pet-safe detergent
- Submerge and press the bed to work water into the padding
- Let it soak 10-15 minutes
- Rinse until the water runs clear
- Press out excess water — don’t wring or twist
Hand washing takes longer, but it’s gentler on foam and bolster construction than most washers.
How to Get Cat Urine Smell Out of a Cat Bed
Regular detergent often fails here because urine odor isn’t just surface-level — it’s chemical.
Uric acid crystals bond to fabric fibers and reactivate with humidity, which is why a bed can smell fine dry and awful the moment it gets damp again. Standard detergent breaks down some compounds but leaves the uric acid behind.
Enzymatic cleaners work differently. They contain bacterial enzymes that digest the uric acid itself, not just mask it. That’s why they outperform vinegar or baking soda on old or repeat stains — those two help with fresh odor, but they don’t touch set-in uric acid the same way.
One rule that matters more than any product choice: never mix bleach with cat urine. The reaction releases chloramine gas, which is toxic to breathe. Stick to enzymatic cleaners or a vinegar-water rinse instead.
Choosing a Safe Detergent for Cat Bedding
This is where most guides stop short — and where cats actually get hurt.
Fragrance-Free Usually Wins
Cats have a sense of smell far more sensitive than ours. A heavily scented detergent can make a freshly washed bed feel foreign enough that your cat refuses to use it.
Ingredients to Avoid
Some common detergent additives are genuinely unsafe for cats, not just unpleasant:
| Avoid | Why |
|---|---|
| Essential oils (tea tree, citrus) | Toxic to cats even in trace amounts |
| Optical brighteners | Can irritate skin on contact |
| Heavy synthetic fragrance | Respiratory irritant for sensitive cats |
| Fabric softener | Coats fibers, can cause skin reactions |

Pet-specific, fragrance-free detergents cost more, but they remove the guesswork. Read the label the same way you’d read one for a baby product.
How to Get Fleas Out of a Cat Bed
If your cat has had fleas recently, washing alone isn’t enough.
Water needs to hit at least 140°F (60°C) to reliably kill flea eggs and larvae in fabric. Most gentle or cold-water cycles won’t reach that, so for a flea-exposed bed, check the label for hot-water tolerance first.
After washing, tumble dry on high heat if the label allows it — heat is more effective than washing alone at killing anything that survived. Combine this with vacuuming the surrounding floor and furniture, since flea eggs don’t stay confined to the bed itself.
Drying a Cat Bed the Right Way
Air-drying is safest for shape and filling. It takes longer, but it prevents the shrinkage and lumping that high heat causes in foam and polyfill.
If you use a dryer, choose low or no-heat settings, and skip dryer sheets — the residue they leave behind can irritate a cat’s skin on contact.
When to Replace a Cat Bed Instead of Washing It
Some beds are past saving. Replace instead of wash if you see:
- Persistent odor after two full wash cycles
- Flattened or lumpy foam that no longer holds shape
- Torn seams exposing internal padding
- Mold or mildew spots (these often return even after washing)
Foam breaks down faster than fabric. A bolster bed with collapsed padding won’t support your cat’s joints properly, even if it still looks okay from the outside.
FAQ: Common Cat Bed Washing Questions
Can I wash a cat bed in the dishwasher?
No. Dishwasher detergent and heat cycles aren’t formulated for fabric or foam, and residue left behind can irritate your cat’s skin.
Can I use a dryer sheet on my cat’s bed?
Skip it. Dryer sheets leave a chemical residue that can cause skin reactions in sensitive cats.
Why does my cat avoid the bed after I wash it?
Usually it’s the scent. Strong detergent or fabric softener can make a familiar bed smell unrecognizable. Switch to fragrance-free detergent and let the bed air out fully before offering it back.
How often should I wash a heated cat bed?
Every 2-3 weeks for the removable cover, following the same schedule as a standard indoor bed. Never submerge the heating element — hand-wash the cover separately and wipe the base with a damp cloth.
