Sharing a home between two or more cats

Cats share best when they do not have to compete

Cats Protection’s guidance on cats and fighting explains that cats like their own space and do not usually need a companion to be happy. They can live together well if they see themselves as part of the same social group, and it helps when they do not feel they have to compete for food, water and comfortable places.

That makes the layout of the home important. This guide uses Cats Protection’s advice to plan where essentials go, and ends with an original resource map you can draw for your own rooms.

Count the essentials: one per cat, plus one

Cats Protection’s home-preparation guidance describes a simple rule: each cat should have one of each essential item, plus a spare for the household. Two cats need three of everything, so one cat cannot block another’s access.

• Food bowls and water bowls.
• Litter trays.
• Beds.
• Scratching posts.

The fighting guidance adds a place to sleep or hide for each cat. Counting is the easy part; where you put each item matters just as much.

Spread resources out of busy areas

Cats Protection recommends keeping essential items out of communal and busy areas and not too close to other cats. It says this matters most for litter trays, because a cat that does not feel safe may have accidents in the home. Its home-preparation guidance suggests placing trays in quiet areas, away from windows, doors and food or water, with space around them to get in and out easily.

• Separate the trays. Three trays side by side in one room work like one large tray. Put them in different places.
• Separate food and water. Cats Protection suggests placing food and water bowls away from each other.
• Avoid windows and cat flaps for essentials. Cats Protection notes that bowls or trays near windows and cat flaps can make a cat anxious if it feels it has to watch for a neighbour’s cat.
• Use more than one level. In a home with stairs, put some resources upstairs and some downstairs.

Add height and hiding places

Cats Protection recommends hiding and climbing places such as boxes and cat trees, so a cat that feels threatened can get away or up high. It specifically suggests adding vertical space in narrow areas like hallways, where cats have less room to avoid one another.

Look at the routes between rooms. A hallway with no shelf, chair or cat tree may be the place where cats meet head-on most often. Our indoor cat enrichment guide covers perches and resting choices in more detail.

Draw a resource map

This is an original Housemates exercise for any home with two or more cats.

1. Sketch the rooms the cats use. Include doors, stairs, windows, any cat flap and the main walkways.
2. Mark every resource. Use a letter for each: F for food, W for water, L for litter tray, B for bed, S for scratching post, H for hiding place, P for a high perch.
3. Count each letter. Compare the totals with the number of cats plus one.
4. Circle the clusters. Where several of the same letter sit together, or a resource sits in a busy route, circle it as a candidate to move.
5. Mark where each cat usually rests. Check that every cat can reach food, water and a tray without passing the other cat’s favourite spot.

Change one thing at a time and keep the old option in place while the cats find the new one. Cats Protection’s home-preparation guidance suggests changing litter type gradually, which is a good general principle for resource changes too.

Watch the household for a week

After you move anything, give the cats time to find the new arrangement. An original way to do this is a simple week of notes. Each evening, jot down where each cat chose to rest, whether any resource seemed unused, and whether one cat often waited or sat near a doorway, tray or bowl while another cat used it.

These are observations about the home, not a verdict on the cats’ relationship. A resource that is never used may simply be in the wrong place; try moving it to a quieter spot or a different level. A doorway where one cat often sits may be a route that needs a second way through, or a perch nearby.

Keep the notes short and factual. They are useful if you later speak to your vet about a change in behaviour or toileting.

Spend time with each cat

Cats Protection recommends playing with each cat individually, for example with a fishing-rod toy, to encourage natural behaviour and reduce stress. Short, separate sessions also let a quieter cat play without competition.

Cats Protection also mentions pheromone diffusers as an option some owners use. Housemates does not test or recommend specific products; ask your veterinary team if you are considering one.

When to get help

Cats Protection advises checking with your vet if a normally calm cat starts showing aggressive behaviour, because there may be an underlying medical cause. Changes in toileting are also a reason to call. A resource map can help you describe the home clearly during that conversation, but it cannot explain why a cat’s behaviour has changed.

If you are bringing a new cat into a home that already has one, start with our first-room guide and introduce them gradually.
