Most kittens train themselves if the tray is the right size, filled with plain sand-like litter, and kept clean in a quiet spot — give one tray per cat plus a spare, away from food, and most cats use it within days1. If a cat that was reliable suddenly stops, check for a medical cause first rather than assuming it's a behaviour problem24.

If your cat stops using the tray

Rule out a medical cause first: a urinary tract problem, feline cystitis, arthritis in an older cat, or another illness can all make a cat avoid the tray, and these need a vet, not training .

How many trays
One tray per cat in the home, plus one extra, in separate quiet spots134
Tray size
About 1.5 times your cat's length, nose to tail base; low sides for kittens or older cats1
Litter
Fine, unscented, sand-like litter, about 3cm deep — most cats dislike scented litter or covered liners1
Placement
Quiet, private spot away from food, water and busy doorways; never right next to a washing machine or a cat flap13
Suddenly stopped using it?
See a vet first — pain, a urinary problem, arthritis or stress can look exactly like a behaviour problem24

Setting up the tray

  1. Pick a tray about 1.5 times your cat's length from nose to tail base — most trays sold as "cat size" are smaller than that1.
  2. Fill it about 3cm deep with a plain, fine, unscented litter. A clumping, sand-like texture is what most cats prefer1.
  3. Put out one tray per cat, plus one spare, in separate quiet spots around the home — not lined up next to each other13.
  4. Keep every tray well away from food, water bowls and busy doorways, and somewhere your cat can get to any time13.
  5. Scoop at least once or twice a day, and wash the tray with hot water (no strong disinfectant) every one to a few weeks1.

Settling a new kitten or cat in

Show your kitten or cat where the tray is as soon as it arrives, before it's had the chance to go anywhere else. If it came from a shelter or another home, ask what litter it was already using — kittens especially tend to prefer whatever litter they first learned on1.

In a small flat, the tray often has to share a bathroom, utility area or balcony corner. That's fine, as long as it's away from food and water and isn't squeezed next to something loud like a washing machine13.

A note for Indian flats

Space is the main constraint in most Indian homes, not the method. If you can't fit one tray per cat plus a spare, put the trays you do have as far apart as possible, and prioritise keeping at least one away from food, water and noise over adding more trays.
