What does a cat actually need?

Litter tray management, resources, play and the health signs that matter, most of which are about environment rather than attention.

Short answer

Cats need choice and control more than attention: multiple resources spread around, a clean litter tray, high places to retreat to, and daily play. Most behaviour problems trace back to resources or stress rather than the cat.

Cats are often described as low maintenance, which leads to their environmental needs being overlooked. Most behaviour problems — spraying, aggression, over-grooming — are stress responses to an environment that does not suit them.

Safety

Lilies are severely toxic to cats — even pollen on the fur can cause kidney failure. Never give a cat paracetamol or other human medication, which can be fatal. A cat straining to urinate, particularly a male, is a genuine emergency and needs a vet immediately.

What you'll need

Litter trays (optional)
High perches (optional)
Interactive toys (optional)

Step by step

Provide one litter tray per cat plus one spare.In separate locations, away from food and away from busy areas. Insufficient or badly placed trays is the most common cause of toileting outside them.
Keep litter trays scrupulously clean.Scooped daily and fully changed regularly. Cats are fastidious and a dirty tray is a common reason they go elsewhere.
Spread resources around the house.Food, water, litter, beds and scratching posts in multiple locations. It prevents competition in multi-cat households and gives choice.
Put water away from food.Cats naturally avoid drinking near where they eat. Separate bowls, and a wide shallow bowl or a fountain, noticeably increases how much they drink.
Provide high places and hiding places.Shelves, cat trees, the top of a wardrobe. Height and the ability to retreat are genuine needs rather than luxuries.
Provide scratching posts, tall and sturdy.Tall enough to stretch fully and stable enough not to wobble. Scratching is a need, and providing for it is what protects furniture.
Play daily with an interactive toy.Ten to fifteen minutes of wand-toy play that mimics hunting. It meets a genuine need and prevents a lot of problem behaviour.
Watch for the health signs that matter.Changes in drinking, appetite, weight, grooming or litter tray use. Cats hide illness well, so these subtle changes are often the only warning.

Tips

A male cat straining in the litter tray without producing urine is a medical emergency. It can be fatal within hours and needs immediate veterinary attention.
Cats drink more from wide shallow bowls or moving water. Increased water intake is genuinely protective against urinary problems.
Sudden behaviour changes, including aggression or house soiling, are frequently pain or illness rather than behaviour. A vet check comes before a behaviourist.

Common mistakes

Having one litter tray for two cats — It causes competition and stress, and toileting outside the tray. The rule is one per cat plus one spare, in separate places.
Putting food and water next to each other — Cats naturally avoid drinking near food. Separating them increases water intake, which matters for urinary health.
Assuming behaviour problems are behavioural — House soiling, aggression and over-grooming are frequently pain or illness. A veterinary check should come first.

Questions people ask

How many litter trays does a cat need?

One per cat plus one spare, in separate locations away from food and busy areas. Insufficient or poorly placed trays is the most common cause of toileting elsewhere.

Why is my cat weeing outside the litter tray?

Common causes are a dirty tray, too few trays, a poor location, stress, or a medical problem. A veterinary check should come first, since urinary conditions are common and painful.
