Holiday guests are on the way. You walk in from the cold, and the first thing you notice is cat. You live with it, so you can't tell where it starts. Your guests will smell it at the door.
Here is the honest answer. A healthy cat and a clean litter box shouldn't make a home smell. So the smell has a source, and you can find it. Work through the ten fixes below in order. Clean each source, then let fresh air in. Don't just cover it up.
One thing first. Has your cat started peeing outside the litter box? Call your vet before you start cleaning. A cat who strains in the box and passes little or no pee is an emergency, especially a male cat.
Start at the Litter Box
Look here first, even if you scoop every day. Then give the box a real reset.
1. Keep the Box Truly Clean
The Feline Veterinary Medical Association says to remove waste at least once a day. It also says to wash the whole box every one to four weeks. Use soap and hot water only. The ASPCA suggests a weekly rinse with baking soda or unscented soap.
Then check the setup:
🧺 Litter box setup check
- One box per cat, plus one extra
- A box that isn't cracked and doesn't smell after a wash (the Cornell Feline Health Center says to replace old boxes that smell or are cracked)
- Unscented, clumping litter, which most cats prefer
- No scented litter, litter deodorizers or box liners, which the Feline VMA says many cats dislike
Plastic gets scratched after years of scooping. If an old box still smells after a good wash, follow Cornell's advice and replace it.
Clean Where the Pee Went
Old pee can hold a strong smell, and it often hides. Find it, then soak it.
2. Find the Spots You Can't See
Dried pee is hard to see, and your nose gets used to your own home. So search low, at cat height, one room at a time. A black light in a dark room helps a lot. Our guide to finding cat pee you can smell but can't see walks you through it, room by room. Mark each spot with tape as you go.
3. Soak Soft Things, Don't Spritz
Pee on a rug, a cushion or a mattress soaks in deep. A light mist only wets the top, so the smell comes back. Soak each spot as deep as the pee went. Wait 10 to 15 minutes, blot hard and let it air-dry. Old spots often need a second round.
Use an enzyme cleaner made for pet urine. Our vinegar vs. enzyme cleaner guide explains why vinegar often falls short. Cornell says to avoid cleaners with ammonia or vinegar, since they smell like urine. Humane World for Animals warns against steam cleaners, too. Their heat can set the stain and the smell for good. For cushions and cleaning codes, see how to get cat pee smell out of a couch.
LitterBond's Urine Odor Eliminator is one option for the soak step. It's a bio-enzyme spray that breaks down cat pee odor at the source instead of masking it. The 400 ml trigger bottle suits rugs and bigger patches. The 100 ml Mist is handy for small spots, like the floor around the litter box. Here is its honest limit. It only works where it reaches, and set-in spots need more than one round.
Spot-test a hidden patch first. It has a light, fresh scent, so open a window and keep your cat away until the spot is dry. Cats are sensitive to essential oils and strong scents. Never spray it on your cat, and never use it with bleach or ammonia.
Freshen the Soft Stuff
Anything soft she sleeps on picks up her smell. Fabric and fur are the next two fixes.
4. Wash Her Bedding and Throws
Wash her bed, the blanket on the couch and any throws she naps on. Unzip cushion covers and wash them too, if the care tag allows it. Humane World has a tip for pet-soiled washables. Add a one-pound box of baking soda to your usual detergent. Air-dry them if you can. Skip strongly scented detergent and dryer sheets on her things.
5. Vacuum the Fur Every Week
Shed fur builds up in rugs, along couch seams and on cat trees. Vacuum those spots once or twice a week while guests are on the way. Use the crevice tool along cushions and baseboards. A damp rubber glove pulls fur off fabric fast. Empty the canister outside when it's full.
Clear the Kitchen Corners
Old food and grimy bowls add their own smell. Both fixes take minutes a day.
6. Scrub Bowls and the Fountain
The US Food and Drug Administration says to wash pet food bowls and scoops after each use. Use soap and hot water. Start with the wet food bowl. A water fountain needs care, too. Take it apart, clean each piece on its maker's schedule and change the filter on time.
That slippery film inside a bowl can be hard to shift with a sponge. LitterBond's Bowl Cleaner Mousse is a foam pump with a silicone brush head. It loosens slimy film and grease, and it rinses clean with no soapy residue. Rinse each bowl until the foam is gone. Plain dish soap and hot water work, too.
7. Seal Food Cans and Take Out the Trash
An open can of cat food on the counter starts to smell fast. The FDA says to promptly refrigerate or throw out leftover canned food. Cover it tightly in the fridge. Toss old food in a tied plastic bag, in a trash can with a lid. The week guests come, take the kitchen trash out every day.
Let the Air Move
Fresh air works best once the sources are gone. It finishes the job. It can't do the job alone.
8. Open Windows, Then Consider a Purifier
Open windows on two sides of the room for a few minutes, even on a cold day. Keep the screens in, or shut your cat in another room first.
An air purifier can help, but it comes last. The EPA names the two best ways to improve indoor air. Remove the sources, and bring in outdoor air. It says filtration can add to those steps.
Check In With Your Cat
Sometimes the smell is your cat, and that's a vet question. Cats groom a lot, so a smelly cat is worth a closer look.
9. Sniff Her Breath, Coat and Rear End
Check these four things during a cuddle.
👄 Breath
The Cornell Feline Health Center says a healthy cat's breath should not be offensive.
🐾 Rear end
VCA Animal Hospitals lists scooting and licking at the rear or tail as early signs of anal sac trouble.
🧶 Coat
A greasy or matted coat can mean she has stopped grooming. CatWatch, a newsletter made with the Cornell Feline Health Center, says this usually comes with other signs of illness, like not eating, hiding or seeming tired.
🚽 Pee outside the box
The Feline VMA says every cat that starts doing this needs a full exam and a urine test.
A cat who tries to pee and passes little or none needs a vet right away. The Cornell Feline Health Center calls a blocked urethra an absolute emergency. Male cats are at greater risk. Don't wait until morning.
Skip the Cover-Up Scents
A plug-in or a candle hides the smell from you. It doesn't remove the source. That's why the last fix is a thing not to do.
10. Don't Mask It With Plug-Ins or Candles
Cornell says odors must be neutralized, not just deodorized, to escape a cat's keen sense of smell. A sweet scent on top only hides an old spot from you. Strong scents can bother your cat, too.
Cats are sensitive to essential oils and strong scents. Already use an oil diffuser? Keep each run short, in a room your cat can't enter. The ASPCA says that's not likely to be a problem. Skip it altogether if she has breathing problems. And never spray scent on your cat to freshen her up.
Plan the Week Before Guests
Spread the work out, and the day before stays easy.
A week before:
- Wash every litter box and refill it with fresh, unscented litter.
- Find old pee spots and soak each one. Use the Urine Odor Eliminator or another enzyme cleaner, then let each spot dry fully.
- Wash her bedding, throws and cushion covers.
- Book a vet visit if anything in fix 9 worried you.
The day before:
- Scoop every box and wipe the floor around it.
- Wash every bowl and take out the trash.
- Vacuum rugs, couch seams and the cat tree.
- Open the windows for a few minutes.

If you do one thing tonight, make it the box. Scoop it, wash it with soap and hot water, and refill it with plain, unscented litter. Then step outside for a minute, walk back in and sniff again. Whatever smell is left will point you to the next fix.

Does a covered litter box keep the smell in?
It may hide the smell from you, but many cats don't like it. The ASPCA says most cats don't like box liners or lids on their boxes, and suggests taking them off.
How deep should the litter be?
About one to two inches. The Cornell Feline Health Center says most cats prefer finer-textured litter at about that depth. The ASPCA adds that most cats like a shallow bed of litter.
How big should a litter box be?
About one and a half times your cat's length. The Feline VMA says a box should be 1.5 times the length of the cat, measured from her nose to the base of her tail.
What if my cat licks or breathes in essential oil?
Move her into fresh air and call your vet. The Pet Poison Helpline lists signs such as drooling, vomiting, wobbliness and trouble breathing. It says a cat whose signs don't quickly clear in fresh air needs emergency vet care. The ASPCA Animal Poison Control Center is at (888) 426-4435.
