Buying Guide
Size and capacity
With two cats, size matters. A larger pan gives both animals room to move and reduces the chance of one cat waiting outside while the other uses the box. Look for an extra-large, deep pan with high sides to contain litter and reduce splashing; multi-pack options also make it easy to put a second box in another room.
- Tip: If your cats are large or one of them is older, choose an XL pan with roomy interior and a low enough entry for older cats to access comfortably.
- Example: For a roomy metal option, consider the 2PACK Stainless Steel XL Litter Boxes which come in a two-pack suitable for multi-cat homes.
Style and access: open vs covered vs automatic
The litter box style affects privacy, odor control and ease of use. Open pans are simple, familiar and often preferred by cats; high-sided open boxes help contain scatter. Covered boxes hide mess and odors but can trap smells and deter some cats. Automatic self-cleaning boxes reduce daily scooping but add cost and occasional maintenance.
- Open/high-sided: Best for cats that dislike enclosed spaces and for easy monitoring of elimination habits.
- Covered: Useful when odor and aesthetics are a priority, but test your cats’ comfort first.
- Automatic: Great for busy households—if you prefer less scooping, an automatic model such as the PETKIT PuraMax 2 automatic litter box can keep the box cleaner between manual scoops. For households wanting to minimize daily cleanup beyond the box itself, consider a complementary cleaning solution like the best robot vacuum for pet hair to pick up tracked litter and fur.
Material and durability
Material affects cleaning, longevity and odor retention. Plastic boxes are lightweight and inexpensive but can stain or retain smells over time. Stainless steel pans resist scratches, don’t absorb odors and are easy to sanitize, making them a strong choice for multi-cat households.
- Plastic: Look for thick, stain-resistant plastic and replace when odors persist despite cleaning.
- Stainless steel: More durable and hygienic for heavy use—many multi-cat owners prefer metal pans for longevity and odor control.
- Consider construction: Smooth interiors, rounded corners and tight-fitting lids (if covered) make cleaning easier and reduce trapped waste.
Cleaning, maintenance and supplies
Ease of cleaning determines how consistently you’ll maintain the boxes. For two cats, plan to scoop at least once or twice daily and replace litter more often than for a single cat. For cleaning tracked litter, consider a robot vacuum such as the best robot vacuum for pet owners. Features that help: removable liners, included scoops, washable mats and self-clean mechanisms in automatic units.
- Have at least two boxes: one per cat plus one extra is a common recommendation—placing them in different rooms reduces crowding.
- Look for accessories: non-stick surfaces, a scooper and a mat to catch tracked litter make daily upkeep simpler—budget-friendly two-packs like the IRIS USA Large 2-Pack high-sided pans include scoops and are easy to clean. For routine floor cleanup around boxes, a specialized unit such as the best robot vacuum for cat hair can save time.
- Automatic units: they cut down on daily scooping but still require periodic deep cleaning and replacement parts or waste bags.
Odor control and litter choices
Odor becomes more noticeable with multiple cats. The box design and your choice of litter both matter. Deeper pans let you keep more litter, which can improve clumping and odor absorption. Consider clumping litters that make scooping easier and non-scented, low-dust formulas if your cats have respiratory sensitivities.
- Routine: Scoop daily, change litter fully on a regular schedule, and wash pans with mild detergent to remove residue.
- Placement: Keep boxes in well-ventilated, low-traffic areas to help odors dissipate and to give cats privacy.
- Test litter types: Some cats prefer fine clumping clay, others do better with natural or crystal litters—try small changes to find what both cats accept. Keeping the area tidy can be easier if you choose cleaning tools suited to your floors—see our best robot vacuum for mixed floors recommendations.
FAQ
How many litter boxes do I need for two cats?
Most behaviorists recommend one litter box per cat plus one extra, so plan for three boxes for two cats. That extra box reduces competition and gives a backup if one is dirty or occupied. Place boxes in different, quiet locations to avoid territorial disputes and accommodate preferences. Scoop daily and deep-clean regularly to keep all boxes inviting.
What’s the best type of litter box for households with two cats?
Durable, easy-to-clean pans with higher sides are often the best choice because they resist odor, scratches, and leakage when used by multiple cats. Stainless steel boxes are non-porous and hygienic — for example, the 2-pack stainless steel litter box is a common pick for multi-cat homes. Open-top high-sided pans reduce scattering and are simple to scoop, while adding one enclosed option can satisfy privacy-preferring cats. Mixing styles and sizes helps prevent avoidance and keeps both cats using their boxes.
Can two cats share an automatic self-cleaning litter box?
They can in some cases, but it depends on the box’s cycle time, capacity, and whether both cats feel comfortable using the machine. Many owners still keep at least one manual box in addition to an automatic model to avoid access issues during cycles. If you want an automatic option, the PETKIT PuraMax 2 is a user-friendly example with safety sensors and app control suitable for smaller multi-cat setups. Monitor your cats for avoidance and keep a conventional box available while they adjust.
How do I stop one cat from hogging the litter box?
Put boxes in separate rooms rather than all together so less dominant cats have private options and easier access. Offer boxes of different shapes or sizes—some cats prefer open roomy pans while others like a covered nook—and keep every box very clean to reduce guarding behavior. Add an extra box if one cat continues to dominate and place it where the shy cat spends time. If space is tight, consider compact solutions and cleaning tools designed for close quarters; our best robot vacuum for small spaces guide is useful for tidy, small-area maintenance. If guarding persists or you see changes in litter habits, consult your vet to rule out medical or stress issues.
What size litter box is best for large or multiple cats?
Choose extra-large, roomy pans so cats can turn comfortably and avoid stepping outside the box, and look for high sides to contain urine and reduce scatter. Open-top XXL-style boxes are usually easiest for multiple cats to share and for you to scoop, while very tall sides help prevent leaks when a cat backs into a corner. Avoid cramped, compact boxes for large cats since lack of space can lead to accidents or avoidance. When in doubt, pick the largest box your space allows and provide multiple options around the home.
Final Verdict
Strong performers stood out by offering true multi-cat capacity, reliable odor control, and low-maintenance cleaning. The best boxes combined roomy interiors or effective self-cleaning mechanisms with high sides or sealed construction to prevent leaks and scatter. For two-cat homes prioritize size, leak prevention, material durability (stainless or sturdy plastic), and how much daily maintenance you’ll accept—automatic units cut work, while high-sided pans offer simplicity and long-term value. Top picks all delivered roomy layouts, easy cleaning, and consistent odor containment. Pairing a low-maintenance litter solution with a robust floor-cleaning unit—see our best robot vacuum with large dustbin picks—can make maintenance even easier.
