Pile fresh hay directly over the litter

Rabbits eat and toilet at the same time, so a tray with no hay in it is just an empty box competing against every corner of the room that smells more interesting. Wild rabbits graze and drop pellets in the same spot without a second thought, and a bare tray simply doesn't trigger that instinct. The moment fresh hay goes into the tray itself rather than a rack across the room, most rabbits start parking there for the long, boring munch-and-go sessions, which is when the bulk of daytime droppings happen anyway. Skip this and you're asking a grazing animal to interrupt eating, hop over, then hop back — most won't bother.

Try it
Heap a thick layer of fresh hay into one end of the tray every morning and evening, not a token handful
Clip the hay rack directly above or to the side of the tray if your rabbit flicks it out, rather than placing it elsewhere in the enclosure
Stop offering hay anywhere else in the room so the tray is the only serious grazing spot
2

Get them neutered before you troubleshoot anything else

Unneutered rabbits scent-mark with urine and droppings as a matter of hormonal instinct, and no amount of tray placement will out-compete that drive. This kicks in hard from around four to six months old — does can spray and scatter-drop, bucks will mark furniture, doorframes, your ankle, all as a deliberate territorial statement rather than an accident. I fostered a lop doe who was spotless as a baby and started leaving piles on the sofa arm the week she hit five months; within a fortnight of being spayed she went back to the tray with zero retraining from me. It's the single biggest lever there is, bigger than any tray or litter you'll buy.

Try it
Book with a vet who specifically lists rabbit spay/neuter experience — it's a different anaesthetic and surgical risk profile to cats and dogs
Expect a settling window of two to six weeks post-op before toileting habits actually improve, not overnight
Keep the tray set-up exactly the same through recovery so you're only changing one variable at a time
3

Put the tray where they already chose, not where you'd like

Rabbits pick a toilet corner within the first few days in a space and it's almost always the same spot, usually the one with the best sightlines for watching the room, so fighting that by placing the tray somewhere tidier for you is the single most common reason litter training stalls. Watch for a day or two before you do anything else: droppings will start building up in one or two corners. Move the tray to that exact spot, even if it's awkward — behind the sofa, under the hutch ramp — and only shift it gradually, a few inches every couple of days, once they're reliably using it.

Try it
Spend a day watching, or check droppings each morning, to spot their chosen corner before buying or placing anything
Put a tray there first, even a cheap temporary one, before investing in a nicer setup
Add a second tray in any other spot they keep using rather than fighting them back to a single tray
4

Switch to paper-based litter, never clumping or clay

Clumping and clay cat litters can cause serious internal blockages if a rabbit ingests any while grooming or nosing through the tray, and rabbits will do exactly that, since digging and mouthing the litter is part of normal toileting behaviour. Paper-based pellets, the kind sold for small animals rather than cat litter, control odour without the dust that puts rabbits off a tray, and unlike wood shavings they won't catch in fur or irritate sensitive feet and airways. A tray that doesn't smell wrong or feel wrong underfoot gets used; one that doesn't, gets abandoned for the carpet.

Try it
Buy paper-pellet small-animal litter, not clumping cat litter or softwood shavings, and line the tray about an inch deep
Layer the hay on top of the litter rather than beside it
Switch gradually over a few days if changing from an existing litter — rabbits can be funny about sudden texture changes
5

Spot-clean daily, strip it down only once a week

A tray that's scrubbed spotless too often actually undoes training, because rabbits toilet by smell as much as memory, and a totally neutral-smelling tray reads as unclaimed territory rather than their spot. Scoop droppings and soaked litter out daily to keep ammonia down, but leave a faint trace of used litter behind rather than rinsing it clean, and save the full wash with mild soap for once a week. Rabbits are genuinely fastidious about a soiled tray in a way some owners don't expect given the mess they're capable of elsewhere, so both extremes, too dirty or too clean, will get a tray rejected.

Try it
Scoop wet patches and droppings out once a day, ideally when you top up hay
Do a full strip-and-rewash with mild, unscented soap once a week, then reintroduce a little of the old litter on top rather than rinsing it spotless
If you foster or keep multiple rabbits, give each their own tray — a shared tray dominated by someone else's scent is a common reason one rabbit stops using it

What didn't make the list

Fancy covered or hooded litter boxes

Marketed hard for odour control and tidiness, but most rabbits find them claustrophobic or awkward to reverse out of, and a nervous rabbit backing out fast tends to miss the edge. A plain open corner tray with high sides on the back two edges beats a hood nearly every time.

Training sprays and scent attractants

Sold as a shortcut for both drawing rabbits to the tray and repelling them from the wrong corners, but in my experience they do almost nothing once a rabbit has picked its own preferred spot — hormones and habit outweigh a squirt of scented spray. Save the money and spend the ten minutes moving the tray instead.

Questions people ask

My rabbit was reliably litter-trained for months and has suddenly stopped. Is this still a behaviour fix?

No — a sudden change in a previously trained rabbit is a vet visit, not a checklist. Rabbits hide illness extremely well and can go downhill fast, so unexplained regression, especially with soft droppings, straining, reduced droppings, or a rabbit that seems quiet in itself, needs a vet's eyes first.

Is it normal for a trained rabbit to still leave the odd dropping outside the tray?

A scatter of dry, round droppings around the house is normal territorial behaviour, especially in a new or shared space, and usually settles down on its own. Wet patches, diarrhoea-like droppings, or a sudden strong new smell are different and worth a vet check rather than more tray-training.

How long should I give this before trying something else?

Give any single change two full weeks before judging it, since rabbits need repetition to build the habit. If nothing has shifted after combining hay placement, the right litter and the right corner, that's the point to loop in your vet to rule out a medical cause rather than trying yet another tray.
