Litter is scattered across the floor. Urine splashed on the wall. A box that somehow never keeps the mess contained.
These problems usually happen when the sides of the litter box are simply too low.
A high sided litter box solves this by adding taller walls, usually between 8 and 16 inches high, which help keep litter and urine inside the box instead of on the floor.
For energetic diggers and cats that stand while peeing, that extra wall height can make a dramatic difference in how clean the litter area stays.
Cats that dig aggressively can easily kick litter out of shallow litter boxes.
Why a High Sided Litter Box Helps
Regular litter pans are designed with relatively shallow walls. That works for calm cats, but it doesn’t contain much mess.
A high sided litter box solves this by adding taller walls usually between 8 and 16 inches high which helps keep litter and urine inside the box instead of on the floor.
The design still keeps the top open, so cats don’t feel trapped the way they sometimes do with covered litter boxes.
For cats that kick litter, dig aggressively, or stand while urinating, those extra inches of wall height can make daily cleanup much easier.
What Is a High Sided Litter Box?
High sided litter boxes use taller walls to keep litter and urine contained.
A high sided litter box is a litter pan with taller walls than a standard litter box.
Most regular litter pans have sides around 4 to 8 inches tall. High sided designs increase the wall height so litter and urine stay contained inside the box.
Many models include a lower entry section so the cat can step inside comfortably.
You may also see these described as:
high sided cat litter box
litter box with high sides
high wall litter box
Some covered and top entry litter boxes technically have tall walls as well. However, when people search for this term they are usually looking for an open litter box with taller sides that still allows airflow and visibility.
Why Regular Litter Boxes Create So Much Mess
Cats that dig aggressively can easily kick litter out of shallow litter boxes.
Low sided litter boxes work well for calm cats that dig gently and squat low when they urinate.
The problem appears when a cat has more energetic bathroom habits.
Aggressive digging
Some cats dig with enthusiasm when covering waste. Litter gets kicked backward and easily clears the edge of a shallow pan.
Standing while urinating
Certain cats stand instead of squatting while they pee. When the wall of the box is too low, urine can hit the rim and run down the outside of the box.
Large cats and cramped boxes
Bigger cats often end up standing close to the edge simply because they need more room. When the sides are short, even normal urination can spill over the edge.
A high sided litter box addresses these situations by increasing the wall height around the litter area.
Benefits of a High Sided Litter Box
Less litter scatter
Tall walls keep kicked litter inside the box instead of on the floor.
Cats that dig vigorously still move the litter around, but it stays contained inside the pan.
Better containment for high sprayers
Cats that urinate while standing benefit significantly from taller sides.
The higher walls help prevent urine from reaching nearby floors, baseboards, or walls.
A cleaner litter area
When the mess stays inside the box, the surrounding area stays cleaner.
That means less sweeping, fewer lingering smells around the litter station, and less time spent cleaning.
Partial privacy without a lid
Covered litter boxes can trap odor and make some cats hesitant to enter.
High sided boxes create a sense of privacy while keeping the top open and well ventilated.
When a High Sided Litter Box Might Not Be the Best Fit
High sided litter boxes work well for many cats, but there are situations where the design needs a little adjustment.
Entry height
Very tall walls can be difficult for kittens, older cats, or cats with joint problems.
Look for a box with a lower entrance cutout so the cat can step inside comfortably.
Interior space
If the litter box footprint is too small, tall walls can make the interior feel cramped.
Cats should still have enough space to turn around and dig normally.
Choosing a larger litter box usually solves this issue.
High Sided vs Covered vs Standard Litter Boxes
| Type | Mess Control | Cat Comfort |
|---|---|---|
| Standard litter box | Low containment | Very open and accessible |
| High sided litter box | Good containment for litter and urine | Open top with added privacy |
| Covered litter box | Strong containment | Some cats dislike the enclosed space |
A high sided litter box often works well as a middle option. It provides more containment than a shallow pan while staying more open and ventilated than a covered litter box.
How High Should the Sides Be?
Standard litter pans are usually between 4 and 8 inches tall.
High sided litter boxes typically range from 8 to 16 inches tall depending on the design.
Cats that kick litter aggressively or urinate while standing benefit from taller walls.
At the same time, the entrance should remain lower so the cat can step into the box easily. An entry height of about 2 to 5 inches works well for most cats.
How to Choose the Right High Sided Litter Box
A few design details determine whether a high sided litter box actually solves the mess problem.
Size and interior space
The litter box should allow the cat to turn around easily.
A common guideline is to choose a box that is about one and a half times the length of the cat’s body.
Large cats especially benefit from oversized litter boxes.
Entry design
Different entry styles suit different cats.
Common designs include:
low front entry
side entry
top entry
Most households do best with a low front entrance because it keeps the tall walls while remaining easy for cats to enter.
Material
Most high sided litter boxes are plastic.
Plastic works well, but scratches can eventually hold odor.
A high sided stainless steel litter box avoids that issue and is usually easier to clean.
Cleaning and maintenance
Look for designs with smooth interior surfaces and rounded corners.
Boxes without complicated seams or ridges are easier to wash during litter changes.
Types of High Sided Litter Boxes
High sided litter boxes come in several different designs. The right style depends on how your cat behaves around the litter box.
Open high sided litter boxes
This is the most common design.
The box has tall walls with a lower entry area in the front. Cats can easily step in while the taller sides help contain litter and urine.
These work well for cats that dig aggressively or stand while urinating.
IRIS open top litter box with high sided walls designed to reduce litter scatter.
One example is the IRIS USA open top litter box with high sided walls, which uses tall side panels to reduce litter scatter while keeping a lower front entrance for easy access.
High sided stainless steel litter boxes
Some high sided litter boxes are made from stainless steel instead of plastic.
Stainless steel does not absorb odor the way plastic can. It also resists scratching, which helps keep the surface easier to clean.
These models are often a good choice for homes dealing with persistent litter box odor.
One example is the Tevila stainless steel litter box with high sides, which uses a metal litter pan combined with a removable splash guard. The guard raises the walls to help contain urine spray while the stainless steel base stays smooth and easy to wash.
The open top design also gives cats plenty of room to move while keeping the litter area well ventilated.
Top entry litter boxes
Top entry litter boxes also have tall walls, but the cat enters through an opening on the lid.
This design helps contain litter scatter because cats step out onto the lid before jumping down.
However, top entry boxes are not ideal for kittens or senior cats that have trouble climbing.
One example is the IRIS USA large top entry litter box, which uses a covered design with an opening in the lid. The textured lid helps remove litter from a cat’s paws as they step out, reducing tracking around the litter area.
The tall walls and enclosed sides also help keep kicked litter inside the box.
Situations Where a High Sided Litter Box Works Best
High sided litter boxes are especially helpful for certain cat behaviors and household setups.
Cats that kick litter everywhere
Some cats dig aggressively when burying waste. Litter gets pushed toward the edge of the box and quickly ends up on the floor.
Taller walls help keep that litter contained inside the box instead of spreading across the surrounding area.
Cats that urinate high
Some cats stand while urinating rather than squatting. When the sides of the box are too low, urine can reach the rim and spill over.
Higher walls provide extra containment that helps prevent urine from reaching the floor or nearby walls.
Large cats
Big cats often feel cramped in smaller litter boxes and may position themselves close to the edge.
A larger high sided litter box gives them more room while still keeping the litter and urine contained. Cats that need extra space may also do better with extra large litter boxes for big cats.
Multi cat households
When several cats share litter boxes, some cats dig more aggressively than others.
Taller sides help keep the litter area cleaner between scoopings, even when multiple cats are using the same box.
You can also improve litter box success by setting up multiple boxes in different areas of the home. A good rule is one litter box per cat, plus one extra.
Maintenance Tips for High Sided Litter Boxes
A high sided litter box helps contain the mess, but regular cleaning still makes a big difference.
Scooping the box daily keeps the litter fresher and encourages cats to continue using it.
During full litter changes, washing the box with warm water and mild soap helps remove residue that can build up along the sides.
Placing a litter mat outside the entrance can also catch small amounts of litter that stick to a cat’s paws when leaving the box.

Final Thoughts
Switching to a high sided litter box is a simple change that can reduce a surprising amount of mess around the litter area.
The taller walls help contain litter kicked during digging and prevent urine from reaching nearby floors or walls.
For cats that dig energetically, stand while urinating, or regularly push litter over the edge of the box, switching to a high sided litter box can make daily cleanup much easier.
