1. The Best Overall Pick: Catit Hooded Cat Litter Pan Kit

While the Catit Hooded Cat Litter Pan isn't a good option if you're short on space, it's the all-around best for pet parents looking for something that can make short work of stinky odors and gives cats plenty of room to do their business in peace. It's equipped with a large hood, which lifts up quickly and easily for cleaning, plus a carbon filter that removes odors as cats use it repeatedly throughout the day.

At 15 inches wide and 22 inches long, it's especially great for multi-cat households or bigger cats. This box gets tons of love from Amazon reviewers, who love its size, cost, durability, and functionality: "My cat and I live in a single bedroom and his litter box is only a couple feet away... but now I don't even remember it's there!" It even comes with a scoop.

2. The Best Top-Entry Litter Box: Modkat Litter Box

This top-entry litter box from Modkat is a great option if you're trying to minimize messes and reduce odors. Since cats have to get out of it vertically, more litter is dropped back into the box and not on your floors, saving you a lot of tidying up time. Other smart design features also go the distance to make cleaning up less of a job for you like a locking swivel lid, which will also help keep litter in the box instead of scattered on your floors. While it's a pricier pick, it's won quite the cult following for its innovative features and sleek, modern design, which is a bonus it your litter box is pretty visible. One reviewer raved: "This litterbox sits discreetly in the corner of my bedroom. MY BEDROOM. Imagine that. There's no smell whatsoever. There might be a hint of a smell right after the kitties go but it doesn't linger very long - if it's even there. The cats took a couple of days to get used to it. One of my cats is very picky and will usually help herself to a giant dump on my bed if I make any changes to her litter box, litter, or food. Surprisingly enough, she didn't!"

To use this, you'll likely want to grab reusable liners from Modkat, since they're tailored to fit it directly and also last for up to three months at a time.

3. The Best Disposable Litter Box: Nature's Miracle Disposable Litter Box

You're probably thinking that these cheap disposable litter boxes from Nature's Miracle would be terrible at containing odors. After all, it's so open and exposed, right? Except the thing is, it's a total game-changer when it comes reducing and preventing odors from forming because of the added baking soda, which provides extra protection against tough litter- and ammonia-related smells.

It's made of recycle paper that doesn't shred or leak (and designed to be landfill-safe), which helps counteract the disposable nature of it. Reviewers say that each box is good for about a month at a time and they come in packs of three. Compatible with all types of litter, these are also a great pick for liners or for trips. "The very best cat litter pan I have ever owned," one reviewer wrote. "Reduces odor. Does not leak. Regular scooping keeps it in long lived shape."

4. The Best Budget Self-Cleaning Litter Box: Omega Paw Self-Cleaning Litter Box

There's a lot to love about this self-cleaning litter box from Omega Paw. One of the biggest reasons? It scoops itself. Just tilt the box and say goodbye to soiled litter — it's that easy. It comes equipped with a grill inside that separates waste and deposits it into a pull-out tray. While it doesn't have the ridiculous convenience of a fully automatic litter box, it's significantly cheaper and definitely a great mid-way point in terms of price if you're looking to up your litter box game without dishing out a fortune in the process.

Amazon reviewers also say that it helps to conserve litter and reduce odor saturation into the air, in part because of its unique self-cleaning method. "Keeping the litter box clean has never been easier," one reviewer raved.

On the plus side, this litter, which won't stick to your cat's paws, is 99 percent dust-free and up to five times more effective at absorbing odors than ordinary litter. To prevent the buildup of smells eventually, reviewers recommend stirring the crystals on a semi-regular or weekly basis. "Size and smell are really critical in my tiny studio. I've been using the Scoop Free for several days and even with 3 cats it doesn't smell. The unit is somewhat large but significantly smaller than two separate boxes. The lidded Ultra version is large enough for my two big males (13 and 15lbs)," one reviewer noted.
