How to get rid of cat poop smell naturally

No one likes the smell of a dirty litter box. But can you imagine if you were the one that had to use that box? No wonder studies have found that at least 10% of cats stop using their litter boxes reliably at some point. Of course there can be medical or behavioral reasons for the problems. But not using the litter box often is traced to nothing more than a dirty litter box.

Here’s how to avoid litter box odor and keep your house smelling fresh, which should make you and kitty happier.

The No. 1 rule, and the only thing that will keep litter box odor at bay, is constant cleaning. That means scooping the box out at least twice a day, removing the solids and liquid clumps if you use clumping litter.

For those who don’t use clumping litter, use a large, solid metal spoon (such as a large kitchen spoon) to lift out the most urine-soaked areas each time you clean. Add litter as needed to replace what is removed.

Also wash the box weekly, or every other week if you are using clumping litter. Use a mild, unscented dish detergent or a mild bleach spray (20 parts water to one part bleach) and rinse well. Clean your scooper also.

When dry, add 2 to 3 inches of litter. Cats don’t like a deep tray of litter and this allows you to add litter as you scoop.

Some litters have perfumes or other additives that claim to help cover litter smell. But to a cat these can smell overwhelming and make the box unwelcoming. Most veterinarians advise against using these products.

Many believe that clumping litters, which allow for the easy removal of solids and liquids, keep boxes smelling fresher. But cats can be very particular about which litters they will use. So experiment to find the litter your cat likes best, then stick with it.

Almost any easily cleaned plastic container can be used as a litter box, but buy the largest box your home can accommodate. A rule of thumb is to get a box that is at least twice as long as your adult cat and as wide as the cat is long.

Cats are fastidious, and don’t want to step or dig in already soiled areas. Many people cut down one side of a large, plastic storage tub to get a larger box.

And avoid covered boxes. Most cats don’t like them, and they can trap odors inside, making it unpleasant for your pet to enter.

Many cats also don’t like plastic liners, which can snare cat’s claws when they dig. This also allows urine to seep under the liner, where it won’t be absorbed by the litter and can cause odors.

As for self-cleaning litter boxes, it depends. Some cats, especially skittish and large cats, may dislike them. But if your cat doesn’t mind, it’s an option for people who are gone for long periods.

The rule is one litter box per cat, plus one. So if you have one cat, you need two boxes. If you have four cats, you need five boxes.

Keep the boxes in different locations in your home. If a cat is on the third floor, and the box is in the basement, they may decide not to make the long trek.

Also, choose the right spots for your litter boxes. Don’t put a box in a small, enclosed area, like a tiny bathroom or closet, which will concentrate litter box odors. A larger, well-ventilated area is best. But it needs to be in a quiet, low-traffic area, away from your cat’s food, other pets, and anything that can startle or scare your cat while they are using the box.

Yes, it takes a daily effort on your part to keep litter box odors at bay. But the result will be a happier cat and a better-smelling home.

Sometimes we cat lovers just have to "get down dirty" when the subject of cleaning up messes arises, namely the pee, poop, and barf accidents that occasionally plague a house with cats. We'll address these separately, as they each require a bit different treatment.

Cat owners should always look for the causes of inappropriate elimination first to eliminate urinary tract disorders and to effectively eliminate the problem.

The most important thing to remember about cat urine is "get it while it's fresh." Urine goes through a decaying process as it "ages" in your carpet, caused by bacteria feeding on the organic wastes, and at the same time, converting it to gasses, primarily that strong ammonia smell.

Aside from the developing odor, the longer you allow urine to remain, the more likely its chances of seeping through the carpet into the pad and/or the wood floor beneath.

Fresh urine can often be cleaned up with the first two steps below, but you'll sometimes need the third:

  1. Blot: Use an old, thick, bath towel and blot up as much liquid as you can with it. Continue with paper towels until no moisture is seen.
  2. Dilute and blot again: Heavily spray the area with clear water or a mild solution of white vinegar and water, then blot again, as above.
  3. Neutralize: If the odor still exists after the carpet is completely dry, it's time to break out the big guns: urine odor removers, based on chemicals, enzymes or bacteria/enzymes, all designed to neutralize the odor by eating the bacteria causing it.

In the case of dried urine, the bacterial process is well underway, and you'll need the help of the odor removal products. Follow the manufacturer's directions for best results. Be aware that if the urine-soaked all the way through to the wood floor underlying, you may need to remove the carpet and padding, and treat the wood directly. You'll have to make the decision whether to attempt to save your existing carpet or re-carpet entirely.

If you are surrounded by the scent of cat urine but can't find any stains, consider investing in a black light, which will illuminate the cat pee, as if by magic. They are readily available in the larger pet stores, as well as online.

If it's firm, you're in luck. Pick up with a paper towel, and then, using a small stiff-bristled brush, clean the area with a mild detergent and water mixture. Follow with steps one and two above. If your cat has diarrhea, clean up as much as you can with paper towels, then clean with detergent and water. Rinse and blot, then follow with a neutralizing product, such as one of the enzymatic cleaners mentioned previously.

Treat vomit stains on the carpet as you would treat feces with diarrhea. If your cat eats canned food containing red dyes, you will probably have to call in a professional, as these dyes are extremely difficult to remove.

Cat owners should try not to take their cats' "accidents" personally, as they are truly accidents, and not done to be stubborn, to punish the owner, nor for any of the other human-type reasons people often assume. Cats are fastidious creatures and will use their litter boxes faithfully if everything else is right in their world. When they suddenly start making mistakes, it's up to us humans to investigate and correct the cause.

If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
