Best Way to Clean a Litter Box

Quick answer. Remove clumps and waste every day if you use clumping litter, change the litter often enough that it looks and smells dry and clean, and scrub the box with a gentle detergent. Do not clean with products that contain ammonia or vinegar. Cornell’s guidance gives no number of days for a full litter change, so use the look-and-smell test. You may not need a new tool: the daily routine works with the scoop you already have. The three products below help, if you want one.
The daily routine
Cornell Feline Health Center’s house-soiling guidance says, “If you use clumping litter, remove feces and clumps daily and add clean litter as needed.” It does not give a schedule for non-clumping litter, so for that type, check the litter maker’s directions.
When to change the litter
The same guidance says, “Litter should be changed often enough so that it looks and smells dry and clean.” It does not give a fixed number of days. Change it when it stops looking and smelling dry and clean.
Washing the box
Cornell advises that the box be scrubbed “with a gentle detergent.” It also warns, “Avoid cleaning products containing ammonia or vinegar as they smell like urine and can be irritating.”
Terms used in this guide
- Clumping litter. Litter that forms solid clumps when wet, so the wet part can be lifted out. Cornell’s daily instruction applies to this type.
- Clumps and solids. The clumps are the wet litter with urine in it. Solids are the stool, which Cornell calls feces. Both come out in the daily scoop.
- Full change. Emptying the box and putting in fresh litter. Topping up is different: Cornell says to “add clean litter as needed” between changes.
- Gentle detergent. Cornell gives no brand or strength. It only says to use a gentle one and to avoid ammonia and vinegar products.
- Open-top, hooded and enclosed. Open-top boxes have no lid. Hooded and enclosed boxes have a cover. The PetLovers scoop listing says it is not for hooded or enclosed boxes.
A checklist for the routine
- Each day: remove clumps and solids from every box, if you use clumping litter. Add clean litter as needed.
- Each day when you scoop: look at the litter and smell it. If it does not look and smell dry and clean, plan a full change.
- Each day when you use a mat: pour collected litter back into the box, then vacuum or roll the mat, as the Drymate listing describes.
- At each full change: scrub the box with a gentle detergent, dry it, and refill it. Do not use ammonia or vinegar products.
- Before you buy a scoop: check that your box is open-top or high-sided and at least 14 inches wide if you plan to use the PetLovers scoop.
Worked example: how many scoops in a week
Take a home with two cats and three boxes, which is Cornell’s count of cats plus one. If you remove clumps daily, as Cornell advises for clumping litter, that is 7 removals per box per week, or 21 across three boxes. The number of removals does not change with the litter brand, but the time each one takes does. The PetLovers listing says its scoop can be used to “scoop, seal and toss with one hand”. The listing does not give a time per scoop, so test the routine in your own home.
Our rule of thumb for other households: multiply the boxes by 7 when you scoop each box once a day. One cat needs two boxes under the cats-plus-one count, so 2 x 7 = 14 removals a week. Three cats need four boxes, so 4 x 7 = 28 removals a week. The counts assume one removal per box per day, which the guidance sets for clumping litter.

When you may not need a mat
The Drymate listing describes its job as containing litter that is kicked out of the box and stuck to paws. If little litter reaches the floor near your box, a mat adds a wash step without a clear gain. We have no measurement of how much litter any mat catches, so decide from what reaches your floor, not from the listing’s claim.
Mistakes to avoid
- Skipping the daily scoop with clumping litter. The guidance is daily.
- Cleaning with ammonia or vinegar products. Cornell warns against them.
- Leaving a mat unwashed. A mat collects litter, and the listing for the Drymate says to wash or vacuum it.
- Buying a scoop that does not fit the box. The PetLovers listing needs a box at least 14 inches wide, and its scoop head is 12.4 inches long and 6.1 inches wide.
- Choosing a mat by its title alone. The Drymate listing’s 28 x 36 inch size is one of several it lists, including 20 x 28 inches, so check the size you buy.
- Leaving collected litter on the mat. The Drymate listing says to pour it back into the box, so the mat is not a place to keep it.
Who should skip this guide
If you use a self-cleaning box, the routine changes, and our self-cleaning guide covers those boxes. If a cat’s urine or stool looks unusual, ask your vet. This guide does not give health advice.
