Before You Buy
Key Buying Factors
01
Height of sides
Taller sides (8 inches or more) reduce urine splash and litter scatter. We measured effective height including any shields.
02
Material durability
Stainless steel resists odors and scratches, while high-impact plastic is lighter. We evaluated resistance to cracking and staining.
03
Cleaning ease
Non-stick surfaces and smooth corners make scooping and washing simpler. We considered how easily the box can be fully cleaned.
04
Size for multiple cats
An extra-large box (over 25 inches long) accommodates multiple cats or large breeds. We measured interior dimensions.
05
Odor control
Material and design affect odor retention. Stainless steel and open tops minimize trapped smells compared to plastic.
06
Value for the feature set
We balanced cost against long-term durability and features like high sides or multi-pack options.
Living With It
Care, Cost and Maintenance
Daily scooping
Remove clumps and solid waste at least once daily to control odors and extend box life.
Weekly deep cleaning
Empty all litter, wash with mild soap and warm water, dry thoroughly before refilling. Avoid harsh chemicals that may absorb into plastic.
Replace when worn
Plastic boxes may develop scratches that harbor bacteria; replace every 1-2 years. Stainless steel lasts indefinitely but check for dents.
Pro tip
If you have a cat that kicks litter, place a large mat under the box and choose sides at least 8 inches high to significantly reduce scatter.
Frequently asked questions
What size litter box do I need for a large cat?
A box at least 24 inches long and 18 inches wide, with 8-inch sides, works well for most large cats. Measure your cat's length from nose to tail base and add a few inches.
Is stainless steel better than plastic for odor control?
Yes, stainless steel is non-porous and does not absorb odors like plastic can. It also resists scratches that trap bacteria and smell.
How often should I replace a plastic litter box?
We recommend replacing plastic boxes every 1 to 2 years, or sooner if you notice deep scratches or lingering odors that cannot be washed out.
Do high sides make it hard for older cats to enter?
If your cat has mobility issues, look for a box with a lower cutout or ramp. Many high-sided boxes have one low side for easy entry.
Can I use a large litter box for multiple cats?
Yes, the rule of thumb is one box per cat plus one extra. An extra-large box can serve two cats if scooped daily, but it is best to have multiple boxes.
