Litter trays and toilet habits

Most litter problems are setup problems, not "spite." Get the basics right and you prevent a lot of carpet disasters.

How many trays?

A common rule: one tray per cat, plus one extra. Two cats → three trays. They don't all need to be in the same room - spreading them reduces guarding and queueing.

Size and type

• Bigger is better; many cats dislike cramped covered trays.
• High-sided trays help messy diggers; easy-entry helps kittens and seniors.
• Covered trays can trap smell and make some cats uneasy - fine if your cat accepts them, not mandatory.
• Liners are optional; some cats shred them.

Where to put them

• Quiet, accessible places - not beside roaring washing machines if you can avoid it.
• Away from food and water.
• On each floor of a multi-storey home if the cat uses those floors.
• Don't hide the only tray behind a constantly closed door.

Litter

Clumping, non-clumping, wood, recycled paper, silica - cats care more about consistency and cleanliness than your preference. Stick to what they know when they first arrive; change type gradually if needed.

Avoid strong scents if your cat is fussy. Depth: enough to dig (a few centimetres for many litters), not a token sprinkle.

Cleaning routine

• Scoop solids and clumps daily.
• Top up litter as needed.
• Full empty, wash tray, and refill on a regular schedule (weekly is a common rhythm; adjust to smell and use).
• Use hot water and mild detergent; rinse well. Heavy disinfectant smells can put cats off.

Accidents - what to check

If a previously reliable cat toilets outside the tray:

1. Medical first - urinary issues, constipation, arthritis (hard to climb in) need a vet, especially with straining, blood, or frequent trips.
2. Cleanliness - would you use it?
3. Competition - another pet blocking access?
4. Change - new litter, new location, new baby gate, quieter before?
5. Type/size - try a larger open tray in a calmer spot.

Clean accidents with an enzymatic cleaner. Don't punish; it increases anxiety and makes things worse.

Kittens

Expect training time. Put them in the tray after meals and naps. Keep them close to the tray in early days. Praise use; clean misses without drama.

Quick checklist

• [ ] Enough trays (n + 1)
• [ ] Scoop daily
• [ ] Quiet locations, away from food
• [ ] Vet check if habits suddenly change
• [ ] Same litter as previous home when a new cat arrives, if known
