Nature's Miracle High-Sided Litter Box Review (2026)

The Nature's Miracle High-Sided Litter Box is an open, lidless box with tall back and side walls and a lower entry. It solves the two classic open-box complaints — kicked litter and cats who spray over the edge — without the hood that some cats refuse and that holds odor in with them.

The full review

We analyzed 12 owner comments across 4 YouTube reviews. The set mixes models — one of the four videos covers the brand's hooded corner box and another reviews its litter boxes generally — and the comment set is small, so we don't draw an owner-sentiment verdict from it. This review is built on the published product design and on well-established litter box guidance. The most-liked comment we read simply thanked a reviewer for showing how the cat actually fit inside — which is the right instinct: size is the first thing to check.

Why high sides and no lid

Most litter box mess comes from two things: cats who dig enthusiastically and fling litter over a low rim, and cats who stand up to urinate and hit the wall — or go straight over it. Tall walls fix both. A lower entry keeps it easy to step into, which matters for kittens and older cats.

The alternative fix is a hood, and hoods have trade-offs. An enclosed box concentrates odor inside, right where the cat's nose is, and some cats don't like having only one exit — particularly in multi-cat homes where another cat can wait by the door. An open high-sided box keeps the mess in while leaving the cat able to see around it and leave in any direction. It also means you see the dirty litter, which is a feature: you scoop more often when you can't ignore it.

Sizing: bigger is almost always better

A commonly cited rule of thumb is that a litter box should be about one and a half times the length of your cat, nose to base of tail. Many standard boxes are too small for adult cats, and a cramped box is one of the common reasons cats start going elsewhere. Before you buy, measure your cat and compare it to the dimensions on the current listing.

How many boxes you actually need

The standard guidance from vets and feline behaviour organisations is one box per cat, plus one — so two cats means three boxes, placed in different locations rather than side by side. A single great box doesn't replace that. If you're replacing one box in a multi-cat home, this is a good model to standardise on, but keep the count right.

Whatever box you choose, it only stays pleasant if you scoop daily and fully empty and wash it on a regular schedule. Open boxes make that easier to remember, not optional.

Quick verdict

What we love
  • ✓Tall back and side walls keep kicked litter and high spray inside
  • ✓Open top — no hood trapping odor around the cat
  • ✓Lower entry keeps it easy to step into
  • ✓Nothing to assemble; easy to see when it needs scooping
Heads up
  • ✕Open design means you'll smell it if you skip scooping
  • ✕Check the dimensions against your cat — size matters more than brand
  • ✕Not a fix for a cat avoiding the box for a medical reason
✓ Buy it if…

your cat kicks litter everywhere or sprays over the rim of a standard box, or has refused a hooded box — and you want a simple, open design.

✕ Skip it if…

you specifically need a covered box to hide the view of the litter, or you're looking for a self-cleaning unit.

A note on your pet's health

A cat that suddenly stops using its box, strains, goes frequently in small amounts, or has blood in its urine needs a veterinarian, not a new litter box — urinary problems can become emergencies, especially in male cats. A new box helps with preference and mess; it can't fix a medical cause. Consult your veterinarian for individual pet health decisions.

Tucker's bottom line

If litter on the floor or spray over the rim is your problem, taller walls are the fix — and an open high-sided box gets you there without the hood that some cats refuse. Measure your cat, keep one box per cat plus one, and scoop every day.

Common questions

Is an open or covered litter box better?
It depends on the cat. Covered boxes hide the view but hold odor inside with the cat and leave one exit; some cats refuse them. Open high-sided boxes keep litter in while leaving the cat free to see and leave. If your cat has ever avoided a hooded box, try open first.
How big should a litter box be?
A commonly cited rule of thumb is about one and a half times your cat's length from nose to base of tail. Measure your cat and compare it with the dimensions on the current listing.
How many litter boxes do I need?
The standard guidance is one per cat, plus one, placed in different locations.
