PetSnowy SNOW+ Review: The Odour Control One
A PetSnowy SNOW+ review covering the TiO2 odour control, automatic waste sealing, the litter control walkway and the ongoing cost of consumable liners.
A photocatalyst odour system, waste sealed into liners, and a walkway that catches tracked litter.
The verdict: The SNOW+ attacks odour harder than any other automatic box, sealing waste into disposable liners and running a titanium dioxide photocatalyst system on top. Buy it if smell is your actual complaint, which it usually is in a flat or a house where the box lives near living space. Skip it if you resent consumables, because the sealed liners and the fragrance cartridges are a recurring cost that a scoop and a bin bag are not.

What it does well
- Sealing waste into a liner rather than dropping it into an open drawer is the single most effective odour measure among automatic boxes.
- The integrated walkway catches tracked litter, which is the second most common complaint about litter boxes and is rarely designed for.
- A modular design makes the deep clean, which every litter box eventually needs, much less unpleasant than dismantling a sealed unit.
- Odour reduction is worth more for a senior cat household than people expect, because a cat with kidney disease produces more urine and it is more concentrated.
Where it falls short
- Liners are a consumable and so are the fragrance cartridges. Over a year that is a real running cost, and it is the thing to price before buying rather than after.
- Fragrance systems mask odour rather than removing its cause, and a sudden change in smell from an older cat's urine is a reason to see the vet, not to add a cartridge.
- Like every enclosed automatic box, the entry is a step up and an arthritic cat may refuse it.
- Sealed waste means you see less of it, which for a senior cat is a genuine loss of information.
What owners report
Published owner reports are strongly positive about odour, which is what the product is designed around, and about the walkway reducing tracked litter through the house. App control and cleaning cycles are described as reliable.
The recurring complaint is the ongoing cost of liners and cartridges, and occasionally the availability of them. Reports from senior cat owners again split on entry height rather than on the machine, which is the constant across this whole category.
Who it suits
- Flats and homes where the litter box is close to living space.
- Households with a cat producing more or stronger smelling urine, alongside a vet visit.
- Owners frustrated by litter tracked through the house.
Who should skip it
- Anyone unwilling to buy consumable liners indefinitely.
- Arthritic cats who need a low open pan.
- Owners who want to see and assess what the cat produced.

A Stainless Steel Fountain for a Senior Cat
Chronic kidney disease is the most common serious diagnosis in older cats, and moving water is the easiest way to raise daily intake. Stainless steel stays cleaner than plastic, which matters on a bowl that runs all day.
Frequently Asked Questions
Do automatic litter boxes really reduce odour?
Yes, because waste is separated from the litter after every use rather than sitting there until you scoop. Sealing it into a liner, as this one does, goes further. What no box does is address the cause, and a sudden change in an older cat's urine odour is a medical sign worth investigating.
What does the TiO2 system actually do?
Titanium dioxide photocatalysis uses light to break down odour molecules on a coated surface. It is a real mechanism used in air treatment, and in a small sealed enclosure it has a reasonable chance of doing something useful. Treat it as a helpful addition to waste sealing rather than the main event.
How much do the liners cost over a year?
That depends on your cat count and how often the box cycles, and it is worth working out before purchase. Any product with a proprietary consumable ties you to the manufacturer's pricing and availability for the life of the appliance, which is a fair thing to weigh against a box that takes a supermarket bin bag.
Is it suitable for a cat with kidney disease?
It handles the increased urine volume well, which is a genuine benefit. The trade is that you see less of what your cat produced, and clump size and frequency are useful information in chronic kidney disease. If you use a sealed box, keep monitoring water intake instead. Our cat water intake chart gives the numbers to compare against.
Will my old cat use it?
That depends almost entirely on the entry height and whether she is comfortable in an enclosed space. Introduce it slowly alongside the existing box, over weeks. If she avoids it, that is information rather than stubbornness, and a low entry pan is the reliable answer for a stiff cat.
