Quick answer: the most widely used rule is one litter tray per cat plus one, spread across different areas. The same goes for food bowls, water stations, scratching posts and beds: several of each, kept apart, so no cat has to walk past another to reach what it needs. High spots and hiding places greatly reduce tension.
Cats can live together very well, but they do not always like to share. Many conflicts between cats do not look like open fights, but rather like subtle blocking: one cat sitting in the hallway leading to the litter tray, or guarding the food bowl. Organising resources well prevents most of these problems.
How many resources you need
| Resource | With 2 cats | With 3 cats |
|---|---|---|
| Litter trays | 3 | 4 |
| Food bowls | 2, kept apart | 3, kept apart |
| Water stations | 2–3 | 3–4 |
| Scratching posts | 2–3 | 3–4 |
| Beds and hiding places | At least 1 per cat | At least 1 per cat |
Litter trays: how to spread them out
- In different rooms, not all together in the same corner.
- With more than one visible exit, so no cat feels cornered.
- Away from food, water and noisy areas.
- Scoop daily: with several cats they get dirty faster.
Food and water without competition
- Each cat with its own bowl, at some distance from the others.
- If one needs a special diet, feed it in a different room.
- Several cat water fountains or bowls around the home, away from the food bowls.
Vertical space
Cats also share out space by height. A cat tree, shelves or secure ledges multiply the places where they can rest and watch without crossing paths. Hiding places (boxes, caves, igloo beds) let them retreat when they need to.
Signs of tension between cats
- One cat blocks hallways, doors or access to the litter tray.
- Hissing, chasing or staring.
- One cat hides much more than usual.
- Urine or faeces outside the litter tray.
- Excessive grooming or loss of appetite.
If you notice these signs, review how resources are laid out and talk to your vet to rule out health problems.

Frequently asked questions
Can two cats share a litter tray?
Some do, but problems often arise. Having three litter trays for two cats greatly reduces the risk.
How do I introduce a new cat?
Gradually: first in a separate room with its own resources, swapping scents, then short, supervised meetings.
