Cats are complex creatures with their own ways of showing affection and dislike. Unlike dogs, cats don’t wear their hearts on their sleeves. You need to watch their body language carefully to understand how they feel about each other. Many people think cats are solitary animals, but this isn’t completely true. While they don’t form packs like dogs, cats can develop strong social bonds. Some cats become best friends, while others merely tolerate each other. A few may never get along. Learning to read cat behavior helps you create a peaceful home. It prevents stress for both you and your pets. When cats get along, they’re happier and healthier. They eat better, play more, and have fewer behavior problems.
Signs That Cats Like Each Other
1. Mutual Grooming
When cats lick each other, it’s called allogrooming. This is one of the clearest signs cats are friends. Mother cats groom their kittens, and friendly adult cats continue this behavior. Grooming serves several purposes. It helps cats bond and shows trust. They can’t reach all spots themselves, so grooming partners help keep each other clean. The act releases feel-good hormones that strengthen their relationship. Watch how they groom. Happy grooming looks relaxed. Both cats take turns being the groomer and groomee. Their eyes may be half-closed, showing contentment. Ears point forward, not flattened. Bodies appear loose, not tense.
2. Sleeping Together
Cats only sleep near those they trust. In the wild, sleeping makes them vulnerable. Choosing to sleep together means they feel safe with each other.
Look for these sleeping positions:
- Curled up together in a ball
- Lying back-to-back
- One cat’s head resting on another
- Sleeping close enough to touch
The closer they sleep, the stronger their bond. Cats that merely tolerate each other might nap in the same room but keep distance between them.
3. Playing Together
Play is serious business for cats. They only play with those they like and trust. Friendly play has these characteristics:
- Taking turns being the chaser and chasee
- Gentle biting with no hissing or yelping
- Brief pauses to rest
- Relaxed body language
Watch their tails during play. A slightly twitching tail shows excitement, not anger. Ears stay forward, not flattened. Their claws stay in most of the time.
4. Rubbing Against Each Other
Cats have scent glands on their cheeks, heads, and bodies. When they rub against each other, they mix their scents. This creates a “group smell” that identifies them as part of the same social unit.
You might see:
- Head-butting (called bunting)
- Cheek rubbing
- Full-body rubs along each other’s sides
- Tail wrapping around another cat
This behavior says, “You’re part of my family.” Cats that do this regularly have a strong bond.
5. Sharing Resources
In nature, cats guard their resources carefully. When cats share without conflict, it shows trust. Look for:
- Eating from the same bowl at the same time
- Drinking together
- Using the same litter box (though having multiple is still best)
- Sharing sleeping spots
- Taking turns with toys
This doesn’t mean forcing sharing is good. Happy sharing happens naturally between cats that like each other.
Signs Cats Tolerate Each Other (But Aren’t Friends)
Not all cats in the same home become best friends. Many simply learn to coexist peacefully. These signs show tolerance, not friendship:
- Passing each other without reacting
- Sitting in the same room several feet apart
- Eating near each other but not together
- Occasional brief grooming sessions
- No fighting, but no play either
This is a neutral relationship. The cats don’t dislike each other, but they’re not close. Many multi-cat homes reach this balance, which is perfectly fine.
Warning Signs: Cats That Don’t Get Along
It’s equally important to recognize when cats dislike each other. Early detection prevents serious fights. Watch for these red flags:
1. Staring With Dilated Pupils
Cats use staring as a threat. Combined with wide pupils, it signals fear or aggression. You might see:
- One cat staring while the other looks away
- Both cats locked in a stare
- Crouched body posture
- Twitching tail tip
2. Hissing and Growling
These vocalizations clearly say, “Stay away!” Hissing is a warning, while growling shows deeper displeasure. Other sounds to watch for:
- Yowling (long, drawn-out meows)
- Spitting (a sharp burst of sound)
- Screaming (during fights)
3. Swatting and Fighting
Playful swats are gentle with claws in. Aggressive swats involve:
- Extended claws
- Ears flattened against the head
- Arched back
- Puffed-up fur
Real fights look and sound scary. Cats may roll together biting and kicking. Fur flies, and loud screams happen. Always break up fights carefully to prevent injury.
4. Blocking Access
One cat may guard:
- Food bowls
- Litter boxes
- Doorways
- Favorite sleeping spots
This shows dominance and creates stress. The bullied cat may stop using resources, leading to health problems.
5. Spraying or House Soiling
When cats feel threatened, they may mark territory with urine. Look for:
- Spraying vertical surfaces
- Urinating outside the litter box
- Defecating in noticeable areas
This signals extreme stress about territory and relationships.
How to Improve Cat Relationships
If your cats don’t get along, don’t despair. You can help build better relationships with patience. Here’s how:
1. Provide Enough Resources
The rule is one per cat plus one extra. This means:
- Food and water bowls
- Litter boxes
- Sleeping areas
- Scratching posts
- Hiding spots
Place resources in different areas so no cat can guard them all.
2. Create Vertical Space
Cats feel safer when they can climb. Install:
- Cat trees
- Wall shelves
- Window perches
Height gives timid cats escape routes and confidence.
3. Use Pheromone Products
Synthetic pheromones mimic natural calming scents. Try:
- Plug-in diffusers
- Sprays
- Collars
These reduce stress and aggression.
4. Try Gradual Reintroduction
For serious conflicts, separate the cats completely. Then reintroduce them slowly:
- Keep in separate rooms
- Swap bedding so they smell each other
- Feed on opposite sides of a closed door
- Use baby gates for visual contact
- Supervise short meetings
- Gradually increase time together
This process can take weeks or months. Patience is key.
5. Play With Them Together
Interactive play builds positive associations. Use:
- Wand toys
- Laser pointers
- Catnip toys
Play sessions should end before they get tired or frustrated.
When to Seek Professional Help
Sometimes cat conflicts need expert intervention. Consult your vet or a cat behaviorist if you see:
- Injuries from fighting
- One cat stops eating or using the litter box
- Constant hiding or stress
- No improvement after months of effort
Medical issues can sometimes cause behavior changes. Always rule out health problems first.
Understanding Different Cat Personalities
Just like people, cats have different social needs. Some types include:
The Social Butterfly
- Loves other cats
- Seeks physical contact
- Plays often
- Adjusts easily to new cats
The Independent Cat
- Tolerates others
- Prefers alone time
- Doesn’t seek interaction
- Needs personal space
The Timid Cat
- Fears other cats
- Hides often
- May be bullied
- Needs safe spaces
The Bossy Cat
- Controls resources
- Stares at others
- Blocks access
- May start fights
Knowing your cats’ personalities helps manage expectations. Not every cat will become best friends with others, and that’s okay.
The Role of Early Socialization
Kittens who grow up with other cats usually adapt better to multi-cat homes. The prime socialization period is 2-7 weeks old. Well-socialized kittens learn:
- Proper play behavior
- Communication signals
- Bite inhibition
- Sharing resources
However, adult cats can still learn to get along. It just takes more time and patience.
Special Cases: Introducing a New Cat
Bringing a new cat home requires careful planning. Follow these steps:
- Prepare a separate room with all necessities
- Let the new cat adjust alone for a few days
- Exchange bedding between cats
- Start feeding on opposite sides of a closed door
- Allow visual contact through a barrier
- Supervise short meetings
- Gradually increase time together
The entire process might take 2-4 weeks. Rushing can create long-term problems.
Final Thoughts
Understanding cat relationships takes time and observation. Look for the positive signs we’ve discussed: grooming, playing, sleeping close, and sharing space peacefully. These show your cats have bonded. Remember that some cats will never be best friends, and that’s normal. The goal is peaceful coexistence, not necessarily friendship. With patience and proper care, most cats can learn to live together without stress. Always respect each cat’s personality and needs. Provide enough resources, space, and attention for all. When in doubt, consult a professional. Your efforts will create a happier home for both your feline friends and your human family.
