Covered vs Open Cat Litter Boxes: Complete Guide

One of the first decisions every cat owner faces is whether to go covered or open with the litter box. It seems like a minor choice, but it shapes how your cat feels about using the tray, how much odour and mess escapes into the room, and how often you reach for the scoop. There is no universal winner here: the right answer depends on your cat's temperament and your home. This guide breaks down both sides so you can choose with confidence.

We have been helping Australian cat owners since 2018, and the covered versus open question is one we field constantly. Here is how the two designs really compare.

Covered (enclosed) litter boxes

A covered cat litter box, also called an enclosed or hooded litter box, has a removable hood that encloses the tray and usually a charcoal filter in the roof.

The upsides:

• Privacy for shy or anxious cats that like to do their business unseen.
• Better odour containment for the room, especially with a charcoal filter.
• Contains litter scatter and stops cats that pee high up the side from hitting the wall.
• Hides waste from view, which keeps living spaces tidier.
• A barrier against curious dogs and toddlers.

The trade-offs:

• Odour builds up inside the hood, which is unpleasant for your cat if you do not scoop often.
• Some cats feel trapped or cornered and will avoid an enclosed box.
• Large cats can struggle to turn around inside a standard hood.
• Out of sight can mean out of mind, so it is easy to forget to clean it.

Best for: nervous cats that want privacy, odour-sensitive households, and homes with dogs. Our pick is the Moderna Flip Cat Enclosed Litter Box, whose flip-up hood makes scooping easy and lifts off completely for cleaning, making it our most popular hooded litter box.

Open litter boxes

An open tray is exactly what it sounds like: a simple box with no lid, available in standard and high-walled versions.

The upsides:

• Better ventilation, so ammonia does not build up the way it can under a hood.
• Cats feel safe with clear sightlines and an easy escape route, which matters in multi-cat homes.
• Easy access for kittens, seniors and cats with mobility issues.
• You can see at a glance when it needs scooping.
• Generally easier and quicker to clean.

The trade-offs:

• Less odour containment, so placement and daily scooping matter more.
• The tray and its contents are on show.
• More litter scatter, though high walls solve most of this.

Best for: cats that dislike being enclosed, multi-cat households where ambush points are a problem, and kittens or older cats. Our pick is the Moderna Casetta Camelia High Wall Cat Litter Box, whose tall sides contain scatter while keeping the open, airy feel many cats prefer.

Which should you choose?

• Anxious or privacy-loving cat:go covered.
• Large cat, or one that dislikes enclosure:go open with high walls.
• Multi-cat home:open or top-entry trays avoid the cornered feeling that causes standoffs.
• Odour or aesthetics are your priority: a covered box or a litter cabinet wins.
• Genuinely unsure: offer one of each and let your cat vote with their paws.

The golden rule is that cats are individuals. Many behaviourists note that cats, given the choice, often favour a large, open, well-ventilated tray, but plenty of cats love the privacy of a hood. Offering both for a week is the fastest way to learn what yours actually prefers.
