How Often to Scoop the Poop. The Ins and Outs of Cleaning Cat Litter Boxes


Keeping a cat’s litter box clean is extremely important for maintaining feline health and preventing foul odors in the home. A dirty litter box can harbor dangerous parasites and bacteria that can lead to illness in cats. Regular cleaning reduces odor and waste buildup, providing a more sanitary environment for cats.

Cats are very fastidious creatures and prefer a pristine litter box. If the litter box becomes too dirty, a cat may refuse to use it altogether and opt to go elsewhere in the home. This can create unsanitary conditions and damage carpets or floors.

By scooping waste daily, disinfecting regularly, and changing out old litter frequently, cat owners can promote good health in their cats and maintain a pleasant smelling home. Establishing a regular cleaning routine tailored to your cat’s needs and preferences helps ensure your feline companion has a sanitary place to take care of business.

Daily Scooping

It’s recommended to scoop your cat’s litter box at least once per day to remove solid waste and clumps. For multi-cat households, aim to scoop the litter box after each use to prevent odor and keep the cats happy. According to veterinarians, litter boxes should be scooped a minimum of once per day, though some recommend scooping after every use (

Scooping daily keeps the litter box cleaner for your cat and prevents smells. Allowing waste to accumulate could deter your cat from using the litter box. For one cat, once daily is usually sufficient. But for multiple cats, scoop after each use to avoid excessive odor and dirtiness.

Weekly Cleaning

It is generally recommended to do a full cleaning and change of the litter box once a week[1]. This involves completely emptying out all of the old litter and washing the box with soap and water. Here is the process for weekly litter box cleaning:

  1. Remove the cat from the litter box area to avoid stressing them during cleaning.
  2. Dump out all of the used litter into a trash bag for disposal. Make sure to empty out any solid waste as well.
  3. Use soap and warm water to scrub down the inside and outside of the litter box, rinsing thoroughly. This helps remove sticky residue and any odors.
  4. Allow the box to completely dry before refilling with fresh litter.
  5. Once dry, pour new litter back in, filling 1-2 inches deep for cats.
  6. Replace the litter box back in its normal spot.

Doing a thorough wash-out weekly helps control odors and gives your cat a clean slate with fresh litter. It’s an important part of maintaining good litter box hygiene.

Monthly Disinfecting

It is recommended to disinfect your cat’s litter box once per month to kill bacteria and prevent the spread of disease. According to veterinarians, disinfecting the litter box monthly helps remove “film that builds up with urine and feces that you can’t see.”

Bacteria from cat feces and urine can accumulate in the litter box and on the surfaces around it over time. Disinfecting the litter box monthly helps sanitize these areas and reduce the spread of potentially harmful bacteria. This is especially important if you have multiple cats sharing a litter box.

To disinfect the litter box, empty all litter and wash the box with soap and hot water. An antibacterial cleaner or diluted bleach solution can also be used monthly to kill bacteria. Make sure to rinse thoroughly after using any cleaning products. Allowing the litter box to dry completely before refilling with fresh litter will help eliminate bacteria.

Monthly disinfecting maintains good hygiene and reduces odor. It provides a deeper clean compared to weekly scrubbing. Disinfecting the litter box regularly can prevent the spread of diseases between cats, ensuring your feline companions remain happy and healthy.

Litter Replacement

Proper litter box hygiene is critical for the health of your cat. The ASPCA recommends replacing all the litter in the box every 1-2 months, depending on the number of cats in the household and frequency of litter box use (1). This helps control the spread of bacteria and remove solid waste material that clumps at the bottom of the box over time.

For homes with multiple cats, err on the side of caution and replace the litter every 4-6 weeks. The more cats using the litter box, the quicker it will become dirty. Some experts suggest replacing 25% of the litter each week if you have 2 or more cats (2).

When changing the litter, dump all the contents into a trash bag for disposal. Wash the litter box with soap and hot water. Rinse thoroughly before refilling with fresh litter. This full cleaning is important to remove urine and fecal matter that can build up.

Replacing the litter regularly helps minimize odors and gives your cat a clean box to use every time. Follow the 1-2 month timeline for litter replacement as a key part of your cat’s health routine.

Spot Cleaning

In addition to regular scooping and full cleanings, it’s important to spot clean the litter box between full cleanings. Urine clumps and any soiled or dirty areas should be scooped out whenever noticed, as leaving them in the box can lead to unpleasant odors. Ideally, check the litter box a couple times per day to spot clean as needed. This helps keep the litter box fresher between full cleanings and prevents smells from building up. According to Reddit users on r/CatAdvice, spot cleaning urine clumps and dirty areas daily is an important habit for keeping the litter box clean.

Litter Box Replacement

Plastic litter boxes should generally be replaced every 6 months. The porous plastic can trap odors and bacteria over time, even with regular cleaning. Scratches in the plastic can also make it more difficult to keep clean. Replacing plastic litter boxes frequently helps maintain good hygiene and odor control.

Clay or ceramic litter boxes are more durable, so these only need replaced every 2 years or so. The glazed surface makes them easier to keep clean long-term. Look for cracks or deep scratches in clay litter boxes as signs it may be time for a replacement. Some wear and tear is normal, butexcessive damage can allow bacteria growth.

You can extend a litter box’s lifespan by providing excellent care between replacements. Daily scooping and weekly scrubbing helps plastic boxes stay fresher for the 6 month mark. Always use mild, pet-safe cleaners on any litter box type to avoid damaging the surface over time.

According to PrettyLitter, the ideal time to replace a plastic litter box is every 6 months, while a ceramic or clay litter box can typically last around 2 years before needing replaced [1]. Replacing on this schedule helps ensure good hygiene for both your cat and your home.

Special Circumstances

There are some special circumstances where you may need to replace the litter box more frequently than the general recommendations. Litter box aversion is one such case where a cat stops wanting to use their litter box. This can happen for a variety of reasons including stress, illness, dislike of litter type, or association of pain or fear with the box. If a cat develops litter box aversion, it’s recommended to replace the litter box itself along with the litter in order to give the cat a fresh start. The new litter box should be in a different location. Other cases where more frequent litter box replacement may be warranted include litter tracking issues, odor problems that persist after cleaning, or if the plastic becomes cracked or warped over time.

According to cat experts, in cases of litter box aversion, replacing the actual litter box can help give the cat a “fresh start” and resolve the aversion ( This approach along with relocation of the litter box and switching litter types can convince the cat to resume regular litter box use.

Signs It’s Time

There are several signs that indicate it’s time to completely replace your cat’s litter box. The most obvious is a strong odor coming from the box, even right after cleaning. Cats have a keen sense of smell and will avoid using a box that reeks of ammonia. Excessive caking and staining on the bottom and sides that can’t be scrubbed away are also good indicators according to FrontPageMeews. If the plastic is warped, cracked, or discolored from years of use, these imperfections can harbor bacteria and make thorough disinfecting difficult.

Clumping litter that doesn’t clump well anymore and instead turns to powder or pieces is another sign as reported by Armand & Hammer. Non-clumping litters that feel more like mud or saturated sawdust also indicate an excess of urine and need replacing. Scratches inside the box from your cat trying to cover waste or urine leaks outside the box are cues your cat is unsatisfied with the cleanliness. Lastly, a box with tears, bite marks, or cracks means it’s worn out and needs replacing according to CatTime.


Keeping your cat’s litter box clean is one of the most important things you can do as a cat owner. By scooping daily, doing a thorough cleaning weekly, disinfecting monthly, and regularly replacing litter, you’ll keep the box inviting for your cat and odor-free for your home. Don’t forget to also spot clean as needed between full cleanings. Replacing the litter box itself every year or two ensures your cat has a sanitary place to do their business.

While the frequency of litter box cleaning depends on factors like number of cats and litter type used, following these general guidelines will help minimize odor and messes. A clean litter box means a happy, healthy cat who feels comfortable and inclined to use their proper facilities. Proper litter box maintenance is essential for containing waste, mitigating risks of illness, and strengthening the bond between you and your furry companion.
