Before You Buy
Key Buying Factors
01
Size & Capacity
We measured interior dimensions to ensure ample space for cats to turn around. Larger boxes reduce accidents outside the box.
02
Splash & Scatter Control
High sides, shields, and hoods help contain litter. We assessed wall height and lid design for effectiveness.
03
Odor Containment
Covered designs, charcoal filters, and materials like stainless steel reduce odors. We checked for ventilation and seal quality.
04
Ease of Cleaning
Sifting trays, smooth surfaces, and removable liners make scooping easier. We considered how each box simplifies maintenance.
05
Durability & Materials
Plastic should be thick and sturdy to withstand scratching. Stainless steel resists stains and smells. We evaluated build quality.
06
Cat-Friendliness
Open tops suit senior cats; enclosed options offer privacy. We looked for entry height and overall comfort for cats.
Living With It
Care, Cost and Maintenance
Daily Scooping
Remove solid waste and clumps at least once daily to control odor and keep your cat happy. Use a slotted scoop for efficiency.
Weekly Deep Clean
Empty all litter, wash the box with mild soap and warm water, and dry thoroughly. Avoid harsh chemicals that can deter cats.
Replace Litter & Box
Change clumping litter entirely every 2-3 weeks, or more often for multiple cats. Replace the box itself if it becomes scratched or stained, as bacteria can hide.
Pro tip
When choosing a litter box, measure your cat from nose to tail and add 8-12 inches for length. Our team always recommends a box that is at least 1.5 times the length of your cat to ensure comfort.
Frequently asked questions
How often should I clean a large litter box?
We recommend scooping daily and doing a full wash and litter replacement every 2-3 weeks. For multiple cats, increase frequency.
Should I get an open or hooded litter box?
It depends on your cat. Open boxes are easier to access and clean, while hooded boxes offer more privacy and odor control. Our team finds many cats prefer open boxes.
What size litter box do I need for a large cat?
A box should be at least 24 inches long and 18 inches wide. We measured our picks to ensure they accommodate large breeds comfortably.
How do I reduce litter tracking?
Choose a box with high sides or a scatter shield, and place a litter mat outside the entrance. In our experience, the WoofiGo stainless steel box minimizes scatter well.
Are stainless steel litter boxes worth it?
Yes, they resist odors and stains better than plastic and are easier to sanitize. However, they are heavier and cost more. Our team recommends them for long-term use.
