Managing a multi-cat household with three cats of different sizes can feel like a juggling act. One cat may prefer a deep, enclosed space while another needs easy entry, and a larger feline might require extra room to turn around. That’s why choosing the right litter box matters more than you think.

In this guide, we evaluate two stainless steel litter boxes from Idymere and Tevila that are designed to accommodate cats of varying body types, from kittens to Maine Coons. Whether you’re dealing with a tiny kitten or a hefty adult, these options offer practical solutions for your multi-cat home.

Buying Guide

Size and Capacity

The right dimensions make all the difference. For three cats with different sizes, you need a box that gives each one enough space to turn around and dig comfortably. The Idymere model measures 16.93″L x 12.99″W x 5.12″H, which suits small to medium cats, while the Tevila XL is a roomier 22.8″L x 14.5″W x 10.2″H, perfect for big breeds like Maine Coons. Make sure the litter box you choose doesn’t feel cramped for your largest cat, or it may avoid using it altogether.

When you’re comparing sizes, think about the available floor space in your home as well. A larger footprint might work if you have a dedicated laundry room, but if you’re tight on space, a compact design with high sides might be a better compromise.

Material and Durability

Stainless steel outshines plastic in almost every way. It doesn’t absorb odors, resists scratches, and is far easier to sanitize. Both the Idymere and Tevila litter boxes use non-porous stainless steel, which means no lingering smells and no hidden bacteria. Over time, plastic litter boxes can develop micro-cracks that trap waste, but metal stays smooth and hygienic, making it a smart long-term investment for a three-cat household.

Durability also extends to the construction. Rounded edges prevent injuries, and the sturdiness of the metal keeps the box from flexing under a heavy cat. If you’ve ever dealt with a warped plastic tray, you know how quickly they can become unusable. Stainless steel eliminates that worry entirely.

Ease of Cleaning

With three cats, you’ll be scooping daily, so the less effort required, the better. The smooth stainless steel surface prevents waste from sticking, letting you rinse and wipe in seconds. The Tevila comes with a scoop and non-slip pads, while the Idymere has a simple, open design that speeds up scooping. Both boxes avoid the hard-to-reach corners that plague many plastic trays, so you won’t be scrubbing grime out of crevices.

If you’re looking for even less maintenance, you might consider automatic options. Check out our best large automatic litter boxes for 2026 to see how they compare for multi-cat homes.

Odor Control and Hygiene

Three cats mean three times the odor, so the litter box material plays a huge role in keeping your home fresh. Non-porous stainless steel doesn’t trap smells like plastic does, so you won’t get that lingering ammonia scent even after cleaning. Both the Idymere and Tevila excel here, but the Tevila’s higher sides also help contain urine splash, reducing mess around the box.

Regular scooping and a good litter type are still essential, but starting with a hygienic base makes a noticeable difference. For a deeper dive into multi-cat solutions, visit our Multi-Cat Litter Boxes category.

Final Thoughts

After evaluating both options, our recommendation depends on your cat mix. For households with smaller cats or kittens, the Idymere Stainless Steel High Sided Cat Litter Box offers a compact, sturdy solution at a budget-friendly size. If you have a large or extra-large cat alongside your smaller ones, the Tevila XL Open Top Stainless Steel Litter Box provides the extra width and height needed for comfortable digging and containment. Both are stainless steel, easy to clean, and built to handle the demands of a multi-cat home, so you can choose based on the physical dimensions of your feline family members.

Frequently Asked Questions

Is stainless steel better than plastic for litter boxes?

Yes, stainless steel is non-porous, which means it doesn’t absorb odors or harbor bacteria like plastic. It also resists scratches and is easier to clean thoroughly. Over time, plastic boxes can degrade, while stainless steel remains hygienic and durable.

How often should I clean a litter box for three cats?

For three cats, it’s best to scoop at least twice a day and completely change the litter every one to two weeks. Stainless steel boxes make this routine easier because they don’t hold onto smells, so a quick rinse with soap and water keeps them fresh. You’ll also want to ensure you have enough litter boxes, ideally one per cat plus one extra.

Can a large cat like a Maine Coon fit in these litter boxes?

The Tevila XL is specifically designed for large breeds, with dimensions of 22.8″L x 14.5″W and a height of 10.2″. This gives a Maine Coon plenty of room to turn and dig. The Idymere model is better suited for smaller cats, but it still has high sides to control scatter.

What accessories are included with these litter boxes?

The Tevila includes a scoop and four non-slip pads to keep the box stable on any floor. The Idymere is a standalone tray, but its simple design means you likely already have a scoop on hand. Both are ready to use right out of the box without extra purchases needed.
