Best litter for rats
A rat will use a corner tray if you give it one. The litter that goes in it is a respiratory decision, not a tidiness one.
Buy Fresh News Original paper pellets: pelleted recycled paper is the format that stays put in a tray instead of being kicked across the cage, it states low dust, and at 25 lb it is the cheapest per use of anything here. The budget pick is the same product, which is unusual and worth saying plainly — the cheapest litter on this page is also the one we rank first. Buy Small Pet Select recycled paper pellets instead if you want a smaller bag from a brand that publishes more about its own processing. Use Kaytee Clean & Cozy White or Oxbow Pure Comfort in the tray only if you are already buying one of them as bedding and want a single product for both jobs; neither is a pellet, so both travel. Every price is live from each listing with its as-of date under the button.
Rat cage floor, bars and bedding · no figure published
a solid floor rather than wire mesh; bar spacing small enough to stop a rat poking its head through; wood chips (non-aspen), cellulose-based chips or shredded filter paper
Two facts about rats make this a smaller question than it looks and a more important one. They are among the easiest small mammals to litter train, because they already choose a latrine corner without being asked. And they have a documented respiratory vulnerability, which means the material in that corner is the material whose dust they will breathe most concentrated.
So the litter is not a convenience purchase. Best bedding for rats handles the floor of the cage; this page handles the tray, where the ammonia is.
What the published guidance rules in and out
- 1.A solid floor rather than wire. The RSPCA publishes this for rats directly, and it is the figure that makes a tray possible at all: a wire floor has nowhere to put one.
- 2.Dust-free bedding. Published as a requirement without a threshold, by every body we have read. Nobody states a particle count, so every dust claim on this page is the manufacturer's.
- 3.No cedar, and pine only with care. The phenol argument, which the Rat Guide states for rats specifically and the House Rabbit Society sets out in the most detail. This rules out the cheapest pet-shop litters outright.
- 4.No clumping cat litter, ever. Not in any published guidance we have found, because it is not sold for rats — but it is what people reach for, and a clumping clay litter is an ingestion and dust problem in one bag.
- 5.Nobody publishes a tray size or a change frequency for rats. Which is why the cadence below is ours and is labeled as ours.
Pine and cedar bedding for rats · recommendation
phenols in cedar and pine may adversely affect the liver and can compromise the immune system, making a rat more prone to respiratory problems resulting from mycoplasma
Why pellets and not shavings in the tray
A tray is a small, concentrated area that gets wet in one place. Loose shavings in that situation do two unhelpful things: they wick the urine sideways until the whole tray is damp, and they get kicked out as the rat turns around, which puts the wet material back on the cage floor you were trying to keep dry.
A pellet is heavier than its own displacement of urine, so it absorbs downward and stays in the tray. It also collapses visibly when it is spent, which turns the change schedule into something you can see rather than smell. That is the entire case for pellets, and it applies to ferret pans for the same reason — best ferret litter boxes covers the pan itself.

Format, dust claim and what each one costs to run
| Product | Format | Stated size | Dust claim | Right job for it |
|---|---|---|---|---|
| Fresh News Original | Pelleted recycled paper | 25 lb | Low dust claimed | The corner tray, in any size cage |
| Small Pet Select paper pellets | Pelleted recycled paper | 20 lb | Dust-extracted claimed | The corner tray, where a smaller bag suits the storage |
| Kaytee Clean & Cozy White | Loose crimped paper | Expanded volume stated on pack | 99.9% dust-free claimed | Cage floor first, tray only as a single-product compromise |
| Oxbow Pure Comfort | Loose crimped paper | Expanded volume stated on pack | Dust-free claimed | Cage floor first; the softest of the four underfoot |
Formats and sizes are each maker's own published figures, read from the listings cited on the cards below. No body publishes a dust threshold for small-animal litter, so every dust claim here is the manufacturer's own and is reproduced rather than verified.
One honest limitation: two of these four are beddings we rank elsewhere and are on this page because people use them in the tray. We have said which job each is actually for rather than pretending all four are litters.
How much, and how often
- Depth in the tray: about an inch. Enough for a pellet layer to absorb downward, not enough to tempt a rat to dig it out. Deeper does not last longer; it just gets kicked further.
- Change: every two to three days for two rats. Our figure, not a published one. The signal is the pellets collapsing, which you can see.
- One tray per level, in the corner they already chose. Rats pick the corner; you are agreeing with them, not training them. Moving the tray to where you would prefer it is the most common reason litter training appears to fail.
- Never scent it. Not the litter, not the tray, not the cleaner. Cage cleaning safely covers the products.
- Keep the floor substrate separate. Different material, different job. The tray wants pellets; the floor wants something a rat can push around and sleep in.
Our pick · Multiple ferrets, or two pans cleaned daily
Fresh News Original Paper Pellet Litter, 25 lb
The cheapest route to the material VCA names, because it is sold as a cat litter: 100 percent recycled paper, non-clumping and unscented, in a 25 lb bag.
- Dimensions
- 25 lb bag (manufacturer-listed)
- Continuous floor
- Not applicable
- Bar spacing
- Not applicable
- Material
- Manufacturer states 100 percent post-consumer recycled paper, unscented, non-clumping, 99 percent dust free
- Why a cat litter is on a ferret page
- VCA's warning is about cat litter a ferret may eat, which in practice means clay and clumping products. This is non-clumping recycled paper — the same material as the small-pet pellets, sold in a cat-sized bag
What it gets right
- Same material as the small-pet paper pellets at a much lower cost per pound
- Non-clumping and unscented, both stated by the manufacturer
- 99 percent dust free by the manufacturer's claim
- 25 lb lasts, which matters when the published routine is daily
What it gets wrong
- Labelled as cat litter, which puts the burden on you to read the material and not the shelf
- Pellet size is set for cats and is slightly larger than the small-pet grades
- No ferret-specific guidance on the bag
- Heavy bag with no handle, and nowhere convenient to store the rest
Who should buy something else
Not for anyone who would rather not have to check a cat-litter label. If any doubt about clay or clumping remains, buy the small-pet paper pellets and pay the difference.

Number 2 · The litter to put in whichever pan you buy
Small Pet Select Recycled Paper Pellet Litter, 20 lb
The litter type VCA names, in the quantity a daily-cleaned pan actually consumes, from a brand whose other products we already rate.
- Dimensions
- 20 lb box (manufacturer-listed)
- Continuous floor
- Not applicable
- Bar spacing
- Not applicable
- Material
- Recycled paper pellets; manufacturer states low dust
- Why pellets
- VCA names a recycled paper pelleted litter for ferrets and warns against cat litter, which ferrets may eat. Pellets are the named format, not a preference of ours
What it gets right
- Recycled paper pellets, which is the format VCA names for ferrets by name
- Pellets do not cling to feet and fur the way loose paper bedding does
- 20 lb box is sized for the daily cleaning routine VCA asks for
- Low dust by the manufacturer's claim, and no added scent
What it gets wrong
- More expensive per pound than a paper-pellet cat litter of the same material
- Pellets are heavy, and a full pan is a weight you notice when emptying it
- Does not control odor as aggressively as a clay litter, which is the trade you are making deliberately
- No published absorbency figure for this product specifically
Who should buy something else
Not a cage-wide substrate for a ferret. Pellets belong in the pan; use fleece or washable liners on the levels.

Number 3 · Reaching a 10 in burrow depth without buying six bags
Kaytee Clean & Cozy White Paper Bedding
Paper, dust-controlled and sold in a volume large enough to actually reach 10 in of depth, which is the spec that matters and the one most bedding bags fail on.
- Dimensions
- Sold in sizes up to 85 L (5,184 cu in) expanded; the 85 L pack is the one we price
- Continuous floor
- One 85 L bag fills roughly 10 in deep over a 500 sq in footprint
- Bar spacing
- Not applicable
- Material
- Virgin kraft paper; manufacturer states 99 percent dust-free
- Absorbency
- Manufacturer states it absorbs up to six times its weight
What it gets right
- Paper, so none of the softwood phenol question applies
- 99 percent dust-free by the manufacturer's own claim
- 85 L pack is one of the few that fills a large enclosure in a single bag
- Holds a burrow shape well once slightly damped
What it gets wrong
- Paper is more expensive per liter than aspen
- The white version shows soiling immediately, which some owners dislike
- Scented variants exist in the range and we would avoid all of them
Who should buy something else
Not for anyone who wants the cheapest possible substrate by volume. Aspen costs less; the trade-off is dust and a less stable tunnel structure.

Number 4 · The toilet corner of a deep-bedded enclosure
Oxbow Pure Comfort Bedding
A paper bedding with better odor behavior than most, which matters in the one corner of the enclosure that always needs it.
- Dimensions
- Sold in 28 L, 36 L, 56 L, 72 L and 178 L packs; the 72 L white pack is the one we price
- Continuous floor
- Not applicable
- Bar spacing
- Not applicable
- Material
- Paper fiber, unbleached options available
- Odor handling
- Marketed on odor control; performs well in a urine corner
What it gets right
- Paper, so no softwood question
- Handles a concentrated urine corner better than aspen
- Unbleached versions avoid the optical brighteners in white paper beddings
What it gets wrong
- Premium price per liter
- Compacts more than kraft paper, so it is not the best deep-burrow substrate
Who should buy something else
Not the whole-enclosure substrate at this price. Buy it for the wet corner and something cheaper for the other nine inches.

What not to put in a rat's tray
Clumping clay cat litter, crystal or silica litter, cedar shavings, pine shavings that are not kiln dried, corn cob, and anything scented. The first two are ingestion risks in an animal that will taste a new substrate. Cedar and untreated pine are the phenol argument. Corn cob grows mold when wet and a tray is wet by design. And scent is a residue in a confined space at nose height.
That list leaves paper pellets and kiln-dried aspen as the defensible options for a rat tray, and of those two, pellets stay where you put them. Best rat cages and rat cage size cover the enclosure the tray goes in.
What we have not done
We have not measured dust, weighed absorbency, or run an ammonia test. The dust and absorbency claims above are each manufacturer's own, cited on the card, and the depth and change-frequency figures are ours because no welfare body publishes them for rats. The only published figures on this page are the RSPCA's solid-floor and dust-free requirements and the phenol argument from the Rat Guide and the House Rabbit Society.
